Answer
As a greenhouse gas, carbon dioxide traps heat in the earth's atmosphere, contributing to global warming. In contrast, renewable energy sources like solar and wind power don't produce carbon emissions as part of the electricity generation process. Instead they harness the natural energy from the sun and the weather. Keep your temperature system on a moderate setting while you're in the room. Use your windows wisely! If your climate control system is on, shut them…if you need a little fresh air, turn off the heat or AC. Cut down the number of appliances you are running and you will save big on energy.On a life-cycle basis, the carbon footprint of renewable energy ranges anywhere from 11 to 740 grams of CO2 equivalent per kWh (gCO2 equivalent per KWh) of electricity produced.Renewable energy has a long-term negative impact on the EF, and for every 1% increase in renewable energy consumption, the energy EF will decrease by 2.91%. The contribution of renewable energy consumption to reducing the EF is 1.34% on average. Most of our energy comes from fossil fuels today. When we burn fossil fuels for energy, carbon dioxide is released, leading to accumulation of greenhouse gasses in the atmosphere and climate change. By switching to renewable energy, we can reduce our carbon footprint by up to 2.5 tons annually. Wind, nuclear, tidal, hydropower, geothermal, solar, and wave energy have the lowest carbon footprint. Per kWh produced, the energy sources emit between 11 and 48 gCO2 on a life-cycle basis. Generating renewable energy creates far lower emissions than burning fossil fuels. Transitioning from fossil fuels, which currently account for the lion's share of emissions, to renewable energy is key to addressing the climate crisis. However, using renewable energy sources will not eliminate all environmental concerns. Although renewable energy sources produce relatively low levels of GHG emissions and conventional air pollution, manufacturing and transporting them will produce some emissions and pollutants.Renewable energy is a critical solution in combating climate change. By transitioning to a low-carbon energy mix, we can reduce greenhouse gas emissions, improve energy security, and provide millions of people access to clean, reliable, and affordable energy. Climate technologies that help us reduce greenhouse gas emissions include renewable energies such as wind energy, solar power and hydropower. To adapt to the adverse effects of climate change, we use climate technologies such as drought-resistant crops, early warning systems and sea walls. CCU technologies are direct air capture (DAC), which extracts CO2 from the air using chemical or physical methods, and electrochemical CO2 reduction, which uses electricity to transform CO2 into carbon-based compounds. CDR encompasses a wide array of approaches, including direct air capture (DAC) coupled to durable storage, soil carbon sequestration, biomass carbon removal and storage, enhanced mineralization, ocean-based CDR, and afforestation/reforestation.

Why renewable energy is important for the future and role of renewable energy in reducing greenhouse gas buildup?
Relevant answer
  • Sep 26, 2023
Answer
Yes, Renewable energy first of all, it is never going to end, we can use them for a long time and various purposes. Also, they generate energy in a large amount and efficiently. The most important benefit of renewable energy is that it is eco-friendly and don't contribute to environmental pollution. Renewable energy differs from fossil fuels principally in their diversity, abundance and potential for use anywhere on the planet, but above all in that they produce neither greenhouse gases which cause climate change nor polluting emissions. Renewable energy in the future is predicted that by 2024, solar capacity in the world will grow by 600 gigawatts (GW), almost double the installed total electricity capacity of Japan. Overall, renewable electricity is predicted to grow by 1200 GW by 2024, the equivalent of the total electricity capacity of the US. Generating renewable energy creates far lower emissions than burning fossil fuels. Transitioning from fossil fuels, which currently account for the lion's share of emissions, to renewable energy is key to addressing the climate crisis. New resources that are being researched or developed include hydrogen, nuclear fusion, ocean thermal energy conversion, and tidal and wave energy. (Solar, wind, and geothermal energy are dealt with in separate fact sheets). One fuel that has the potential of being widely used in the future is hydrogen gas (H2). RNG is often touted as a "fuel of the future" due to its low-to-negative carbon intensity and its interchangeability with fossil natural gas. For example, the average annual carbon intensity of bio-CNG under the California Low Carbon Fuel Standard in 2022 was -92.26 gCO2e/MJ.India aims for 500 GW of renewable energy installed capacity by 2030. India aims to produce five million tonnes of green hydrogen by 2030. This will be supported by 125 GW of renewable energy capacity. 57 solar parks with an aggregate capacity of 39.28 GW have been approved in India. Transmission of electricity from areas where solar and wind energy are plentiful to other parts of the country, storage of energy from intermittent sources such as wind and solar, and a more flexible and efficient electrical grid, or “smart grid,” are all ways to expand the adoption of renewable electricity. Renewable energy sources which are available in abundance all around us, provided by the sun, wind, water, waste, and heat from the Earth are replenished by nature and emit little to no greenhouse gases or pollutants into the air. That's because renewable energy sources such as solar and wind doesn’t emit carbon dioxide and other greenhouse gases that contribute to global warming. Renewable energy is a critical solution in combating climate change. By transitioning to a low-carbon energy mix, we can reduce greenhouse gas emissions, improve energy security, and provide millions of people access to clean, reliable, and affordable energy.

How can we reduce greenhouse gas emissions in energy production and which renewable energy produces greenhouse gases?
Relevant answer
  • Sep 26, 2023
Answer
Climate technologies that help us reduce greenhouse gas emissions include renewable energies such as wind energy, solar power and hydropower. To adapt to the adverse effects of climate change, we use climate technologies such as drought-resistant crops, early warning systems and sea walls. Greenhouse gas emissions can be reduced by making power on-site with renewable and other climate-friendly energy resources. Examples include rooftop solar panels, solar water heating, and small-scale wind generation, fuel cells powered by natural gas or renewable hydrogen, and geothermal energy. Now, more ambitious goals are set that include a net 55% or greater reduction below 1990 levels by 2030 and a climate-neutrality objective by 2050. Reaching these goals will require even higher emission cuts through transitioning from fossil fuels to clean, renewable energy. This in turn leads to impacts such as shifting seasons, rising sea-levels, disappearing Arctic sea-ice and more intense heat waves. By rapidly cutting emissions of greenhouse gases we can lessen the risks of dangerous climate change. Carbon dioxide is widely reported as the most important anthropogenic greenhouse gas because it currently accounts for the greatest portion of the warming associated with human activities. This official said a substantial increase in forest cover and schemes promoting non-fossil generation and targeting emissions in industrial, automotive and energy sectors has led to the sharp reduction in India's emissions intensity. As of 2019, forests and trees covered 24.56%, or 80.73 million hectares, of India. Modern biomass systems include dedicated crops or trees, residues from agriculture and forestry, and various organic waste streams. Energy created by burning biomass creates greenhouse gas emissions, but at lower levels than burning fossil fuels like coal, oil or gas. Passive solar heating presents the most cost, effective means of providing heat to greenhouses. Generally, the amount of solar energy that falls on the roof of a greenhouse is more than the total energy consumed within the greenhouse. Geothermal is commonly considered to be a clean, green energy source but it does produce some greenhouse gas emissions, particularly CO2. The amount of CO2 is usually measured as an emission intensity of kg of CO2 emitted per MWh of electricity produced.Solar energy technologies and power plants do not produce air pollution or greenhouse gases when operating. Using solar energy can have a positive, indirect effect on the environment when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment. Based on the literature reviewed, we find that hydropower development does emit greenhouse gases (GHGs), but the rate of emissions per unit of electric generation from hydropower (excluding tropical reservoirs) is much lower than for fossil fuel technologies. A solar energy greenhouse is a structure that has solar panels installed. They collect the light from the sun and transform it into heat. It provides the right environment for the growth of plants even in unfavourable climatic conditions. Renewable energy sources include solar energy, geothermal energy, wind turbines, ocean wave and tidal energy, waste and biomass energy, and hydropower. Because they do not burn fossil fuels, these renewable energy sources do not release greenhouse gases into the atmosphere as they generate electricity. Most kinds of renewable energy are also “carbon-free”: they do not emit CO2 or other greenhouse gases into the atmosphere. Because of this, and because renewable like wind and solar power are so popular in climate activism, the terms “renewable energy” and “carbon-free energy” are sometimes confused.Using renewable energy sources rather than fossil fuel to generate electricity. Increasing the share of total electricity generated from wind, solar, hydro, and geothermal sources, as well as certain biofuel sources, through the addition of new renewable energy generating capacity. Generating electricity and heat by burning fossil fuels – coal, oil, or gas – causes a large chunk of the greenhouse gases, such as carbon dioxide and nitrous oxide that blanket the Earth and trap the sun's heat.

What is the best renewable energy source in the world and which renewable energy is the best source to provide electricity in India?
Relevant answer
  • Sep 26, 2023
Answer
Hydropower is the world's largest source of renewable energy and produces negligible amounts of greenhouse gases and played an important role in world's dependency on fossil fuels. At present, wind power is the most efficient method of sustainable energy production. One fuel that has the potential of being widely used in the future is hydrogen gas (H2). Like natural gas, hydrogen can be burned to heat buildings, cook food, and produce electricity in power plants. Should hydrogen replace natural gas, the existing natural gas pipeline network could be modified to transport hydrogen. Fossil fuels are the dirtiest and most dangerous energy sources, while nuclear and modern renewable energy sources are vastly safer and cleaner. Renewable are the cheapest form of power today confirms a new report from the International Renewable Energy Agency. Amid climbing fossil fuel prices, investments in renewables in 2021 save US$55 billion in global energy generation costs in 2022.Concentrated solar power (CSP): This resource is the most expensive renewable, costing an average of $182 a megawatt-hour. Despite this high cost, it competes well with fossil fuels in some cases, as it is more consistently reliable than other renewable. Onshore wind is now one of the most competitive sources of electricity available. Technology improvements, occurring at the same time as installed costs have continued to decline, mean that the cost of onshore wind is now within the same cost range, or even lower, than for fossil fuels. Thermal power is the "largest" source of power in India. There are different types of thermal power plants based on the fuel used to generate the steam such as coal, gas, and Diesel, natural gas. About 71% of electricity consumed in India is generated by thermal power plants. Wind is now the cheapest source of renewable energy in India. Solar Power: 67.07 GW. Biomass/Co-generation: 10.2 GW. Small Hydro Power: 4.94 GW. Solar power is much cheaper than produced by any other sources. India has surpassed its renewable energy target of 175GW by 2022 and is expected to reach 174GW by 2023, according to a report by the International Energy Agency. The country's renewable energy capacity is projected to grow to 280 GW by 2025, accounting for 37% of the total energy supply. Renewable energy technologies can support rural development by providing access to energy to rural communities, which can help to improve quality of life, increase agricultural productivity and stimulate economic growth. Coal is the most important and abundant fossil fuel in India. It accounts for 55% of the country's energy need. The country's industrial heritage was built upon indigenous coal. Commercial primary energy consumption in India has grown by about 700% in the last four decades. The country boasts one of the largest manufacturing ecosystems for wind energy and is experiencing rapid growth in solar capacity, propelling India to be the global leader in renewable energy.

Relevant answer
  • Sep 24, 2023
Answer
According to statista.com and hydropower.org, hydropower plays a significant role in Nigeria’s energy sector and contributes to the economy in several ways:
  1. Energy Production: As of 2022, hydropower accounted for about 27% of Nigeria’s power production. The total installed capacity is 12,522 MW, of which 2,062 MW is hydropower.
  2. Economic Growth: The government has set hydropower development targets of 12,801 MW for 2030 to support its ambitious economic growth target.
  3. Job Creation: Developing and maintaining hydropower plants create jobs and stimulate economic activity.
  4. Rural Electrification: Hydropower projects help extend electricity to rural and remote areas, improving living standards and promoting economic development.
In terms of competitiveness, hydropower in Nigeria has several advantages:
  1. Abundant Resources: Nigeria has large rivers and natural falls that provide rich hydropower potential.
  2. Untapped Potential: The total exploitable potential of hydropower is estimated at over 14,120 MW, amounting to more than 50,800 GWh of electricity annually. This indicates a significant opportunity for further development.
  3. Government Support: The Nigerian government prioritizes fully harnessing the country’s hydropower potential and promotes private sector participation in its development.
However, despite these advantages, the competitiveness of hydropower in Nigeria is affected by several challenges:
  1. Investment and Management: Nigeria is ranked economically water-scarce due to a lack of investment and management to meet demand.
  2. Infrastructure Development: The development of hydropower infrastructure requires significant capital investment and time.
  3. Environmental Impact: Hydropower projects can have environmental impacts that must be managed carefully to ensure sustainability.
While hydropower significantly contributes to the Nigerian economy and possesses competitive advantages, its full potential is yet to be realized.

Which renewable energy has the highest capacity factor and role of renewable energy resources in order to maintain the environment sustainability?
Relevant answer
  • Sep 20, 2023
Answer
Nuclear has the highest capacity factor of any other energy source producing reliable, carbon-free power more than 92% of the time in 2021. That's nearly twice as reliable as a coal (49.3%) or natural gas (54.4%) plant and almost 3 times more often than wind (34.6%) and solar (24.6%) plants. Solar energy has the greatest potential among all the given sources of renewable energy. Photovoltaic technology has the highest power density of all renewable energy sources. It is also the only renewable source that has experienced a positive relationship in power density over time. Capacity factor is a measure of how much energy is produced by a plant compared with its maximum output. It is measured as a percentage, generally by dividing the total energy produced during some period of time by the amount of energy the plant would have produced if it ran at full output during that time. In terms of installed capacity, solar and hydropower are currently the leading sources of renewable energy in India. With an installed capacity of more than 52 gigawatts, India is among the world leaders in cumulative hydropower capacity. Meanwhile, solar power capacity surpassed 63 gigawatts in 2022. The highest energy density fuel is hydrogen, the simplest chemical component. Gasoline, which is derived from refining crude oil, contains much more energy than coal (twice the lower grade bituminous) or wood (three times). For instance, when compared to coal-fired power plants, electricity from renewable energy sources emits between 90 and 99% less greenhouse gases (GHGs) and produces 70 to 90% less pollutants. These technologies also create jobs and stimulate economic growth, which is essential for sustainable development.The use of renewable energy can significantly reduce the amount of carbon emissions released into the atmosphere and help combat the negative impacts of climate change. By transitioning to a low-carbon energy mix, we can also reduce the risk of extreme weather events. Renewable sources are environmentally friendly and low-carbon energy sources. Solar, wind, geothermal, and hydroelectric power do not produce greenhouse gases (GHGs). In recent years, many countries have adopted renewable energy technologies to protect the environment. Renewable energy is good for both humans and the environment. Non-renewable energy like fossil fuels causes pollution and environmental hazards like acid rain, global warming, etc. The amount of carbon emissions from renewable energy is much low than those of non-renewable energy. Renewable energy projects sometimes raise significant sustainability concerns, such as risks to biodiversity when areas of high ecological value are converted to bioenergy production or wind or solar farms. Hydropower is the largest source of renewable electricity while solar and wind energy are growing rapidly. For instance, when compared to coal-fired power plants, electricity from renewable energy sources emits between 90 and 99% less greenhouse gases (GHGs) and produces 70 to 90% less pollutants. These technologies also create jobs and stimulate economic growth, which is essential for sustainable development.

Question
3 answers
  • Sep 18, 2023
What are the effects of providing energy on ecosystems and the environment and impacts of renewable energy generation on environment?
Relevant answer
  • Sep 19, 2023
Answer
The effects of providing energy on ecosystems and the environment can vary significantly depending on the energy source and how it is extracted or generated.
Here are some key considerations for different energy sources and the impacts of renewable energy generation on the environment:
Conventional Energy Sources (Fossil Fuels and Nuclear):
  1. Greenhouse Gas Emissions: The combustion of fossil fuels (coal, oil, natural gas) releases carbon dioxide (CO2), methane (CH4), and other greenhouse gases, contributing to global warming and climate change. Nuclear power generation does not produce greenhouse gas emissions during operation, but it has other environmental concerns related to uranium mining and radioactive waste disposal.
  2. Air Pollution: Fossil fuel combustion emits pollutants such as sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter, leading to air quality issues, respiratory problems, and acid rain.
  3. Habitat Disruption: Extracting fossil fuels through mining and drilling can disrupt ecosystems and lead to habitat destruction.
  4. Water Use: Many conventional power plants, including nuclear and fossil fuel-based ones, require significant amounts of water for cooling, which can affect aquatic ecosystems.
Renewable Energy Sources:
  1. Solar Energy:Land Use: Solar panels require land or roof space, which may compete with natural habitats. However, this impact is generally lower than that of fossil fuel extraction or large-scale agriculture. Manufacturing: The production of solar panels involves the use of materials and energy, but the environmental impact is typically lower compared to fossil fuels. No Greenhouse Gas Emissions: Solar power generation does not produce greenhouse gas emissions during operation.
  2. Wind Energy:Bird and Bat Collisions: Wind turbines can pose a risk to birds and bats if located in migration paths. Proper site selection and mitigation measures are essential to minimize these impacts. Land Use: Wind farms require land, but this land can often still be used for agriculture or other purposes. Low Greenhouse Gas Emissions: Wind power generation has minimal greenhouse gas emissions during operation.
  3. Hydropower:Habitat Disruption: Large-scale dams can disrupt river ecosystems, alter water flow, and affect fish populations. Methane Emissions: Decomposing organic matter in reservoirs can produce methane, a potent greenhouse gas. Low Greenhouse Gas Emissions: Generally, hydropower has low greenhouse gas emissions compared to fossil fuels.
  4. Biomass Energy:Air Pollution: Burning biomass can release pollutants and contribute to air quality issues. Sustainable Sourcing: Sustainable forestry and agriculture practices are needed to minimize habitat destruction. Carbon Neutrality: Biomass energy can be carbon-neutral if managed sustainably.
  5. Geothermal Energy:Minimal Environmental Impact: Geothermal power generation has low environmental impact and greenhouse gas emissions compared to fossil fuels. Localized Ecosystem Effects: Local ecosystems may be affected by drilling for geothermal reservoirs.
In summary, renewable energy sources generally have lower environmental impacts compared to conventional sources like fossil fuels and nuclear energy. However, renewable energy generation is not entirely without environmental consequences, and its impacts can vary depending on factors such as site selection, technology used, and sustainability practices. Careful planning and mitigation measures are essential to minimize the environmental footprint of renewable energy projects. Transitioning to renewable energy sources is seen as a critical step in mitigating climate change and reducing the overall environmental impact of energy production.

  • Sep 18, 2023
How wind is power a clean and renewable energy source and does the use of solar and wind energy over other energy sources help our environment?
Relevant answer
  • Sep 19, 2023
Answer
Not only is wind an abundant and inexhaustible resource, but it also provides electricity without burning any fuel or polluting the air. Wind continues to be the largest source of renewable power in the United States, which helps reduce our reliance on fossil fuels. The use of clean energy sources, such as water, wind, sunlight and nuclear, to generate electricity helps to reduce greenhouse gas emissions and mitigate climate change. This is because clean energy sources don't emit any greenhouse gases, such as carbon dioxide, during the electricity generating process. Wind power is a clean and renewable energy source. Wind turbines use blades to collect the wind's kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity. The wind is a more efficient power source than solar. Wind turbines release less CO2 to the atmosphere. A wind turbine produces 4.64 grams of CO2/1kWh while the solar panel produces 70 grams of CO2/1kWh. Wind power consumes less energy and produces more energy compared to solar panels. Wind and solar power were emerging technologies with a minimal market share back in 2000, but they are now the fastest-growing electricity sources in the US. According to the Solar Energy Industries Association (SEIA), solar power accounts 43% of the capacity added in 2020, while wind power accounts for 38%. Wind is a renewable energy source. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind turbines do not release emissions that can pollute the air or water and they do not require water for cooling. Wind, solar, and hydroelectric systems generate electricity with no associated air pollution emissions. Geothermal and biomass systems emit some air pollutants, though total air emissions are generally much lower than those of coal- and natural gas-fired power plants. Renewable energy is energy that comes from a source that won't run out. They are natural and self-replenishing, and usually have a low- or zero-carbon footprint. Examples of renewable energy sources include wind power, solar power, bioenergy (organic matter burned as a fuel) and hydroelectric, including tidal energy. Wind and solar energy provide air-quality, public health, and greenhouse gas emission benefits as they reduce reliance on combustion-based electricity generation. In the United States, these benefits vary dramatically by region and over time. Clean energy is the generation of energy that does not produce greenhouse gas emissions. Renewable energy is the generation of energy from sources that can be replenished naturally over time. The differences between the two have different implications for reducing global greenhouse gas emissions. It is possible to supply about 75-80% of US electrical needs. If the system were designed with excess capacity (the 150% case), the US could meet about 90% of its needs with wind and solar power. It all comes down to cost and infrastructure. Ultimately, the biggest hindrance to the development of renewable energy is its cost and logistical barriers. Once the infrastructure for renewable energy sources grows, we will see it take off in popularity and use. Solar energy does not generate waste or contaminate water—an extremely important factor given the scarcity of water. Unlike fossil fuels and nuclear power plants, wind energy has one of the lowest water-consumption footprints, which makes it a key for conserving hydrological resources.

Can clean energy replace fossil fuels and what are the economic impacts of renewable energy?
Relevant answer
  • Sep 18, 2023
Answer
Yes, clean energy has the potential to replace fossil fuels. According to the World Economic Forum, studies show that renewable energy sources like wind, solar, and hydropower could replace fossil fuels by 2050. However, this transition would require significant initial costs and full support from policymakers, investors, and other relevant organizations. For these reasons and other technical and financial considerations, perhaps fossil fuels will remain part of the energy mix in several countries in 2050.
The economic impacts of renewable energy are quite positive. According to IRENA, doubling the share of renewables in the energy mix by 2030 could increase global GDP by up to 1.1% and improve welfare by up to 3.7%. This transition would also create significant employment opportunities across various sectors, such as construction and manufacturing. According to IRENA, it’s estimated that over 24 million jobs could be supported in the renewable energy sector. Therefore, while the transition to renewable energy requires substantial investments, it leads to long-term savings and positively affects global Gross Domestic Product (GDP), according to UNDP.

Answer
Solar energy technologies and power plants do not produce air pollution or greenhouse gases when operating. Using solar energy can have a positive, indirect effect on the environment when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment. For setting up a solar power plant requires a large expanse of land, which is completely cleared, leading to soil erosion. Also, improper disposal of chemicals used during manufacturing can lead to water, air, and soil pollution. As a renewable source of power, solar energy has an important role in reducing greenhouse gas emissions and mitigating climate change, which is critical to protecting humans, wildlife, and ecosystems. Solar energy can also improve air quality and reduce water use from energy production. There has been a visible impact of solar energy in the Indian energy scenario during the last few years. Solar energy based decentralized and distributed applications have benefited millions of people in Indian villages by meeting their cooking, lighting and other energy needs in an environment friendly manner. Although renewable energy sources produce relatively low levels of GHG emissions and conventional air pollution, manufacturing and transporting them will produce some emissions and pollutants. The production of some photovoltaic (PV) cells, for instance, generates toxic substances that may contaminate water resources.The environmental impacts associated with solar power can include land use and habitat loss, water use, and the use of hazardous materials in manufacturing, though the types of impacts vary greatly depending on the scale of the system and the technology used—photovoltaic (PV) solar cells or concentrating solar thermal. Hydroelectric has the greatest impact on the aquatic environment, while geothermal plants and biomass have the least. Table 5 Environmental effects of different renewable energy sources. Hydroelectric power plants are the most damaging to the environment compared to other renewable energy sources. The environmental problems directly related to energy production and consumption includes air pollution, climate change, water pollution, thermal pollution, and solid waste disposal. The emission of air pollutants from fossil fuel combustion is the major cause of urban air pollution. Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed.

Answer
The emission of air pollutants from fossil fuel combustion is the major cause of urban air pollution. Burning fossil fuels is also the main contributor to the emission of greenhouse gases. Diverse water pollution problems are associated with energy usage. One problem is oil spills. Non-renewable energy resources release harmful greenhouse gases into the atmosphere, creating the greenhouse effect which causes global warming. Non-renewable energy sources are also harmful pollutants and lead to habitat destruction. The production of some photovoltaic (PV) cells, for instance, generates toxic substances that may contaminate water resources. Renewable energy installations can also disrupt land use and wildlife habitat, and some technologies consume significant quantities of water. Despite the negative impact on wildlife, renewable energy still positively impacts the climate and the air. It fosters a stronger ecosystem because it is clean. The production of this electricity also has no impact on the environment. Unlike fossil fuels, renewable energy creation doesn't harm the ecosystem. Renewable resources are jeopardized by unregulated industrial expansion and growth. They must be carefully controlled to safeguard them beyond the capacity of the natural world to replenish them. A life cycle evaluation is a strategy for methodically analysing renewability. Using renewable energy can lead to several social impacts, including poverty elimination, climate change mitigation, and improving health by reducing pollution associated with gas emissions. The costs include: infrastructure investment, day-to-day operations, market costs of supply and the environmental costs of the different energy sources. The International Renewable Energy Agency's 2021 Renewable Energy and Jobs annual review projects that global renewable energy jobs will increase from 12 million in 2020 to 38 million by 2030 and 43 million by 2050. Although India has made progress in developing its renewable energy sector, it still faces obstacles. Off-taker risk, lack of infrastructure, lack of financial intermediaries, and lack of investor understanding are the top four challenges to overcome. One of the main environmental risks of renewable energy is the impact on land use and habitat loss. Wind and solar farms require large areas of land to generate enough electricity, which can displace wildlife, reduce biodiversity, and affect ecosystem services. The environmental impacts related to energy production include climate change, acidification, impacts on waterways, and waste production. Some common environmental and energy efficiency issues include global warming, air pollution, waste disposal, water pollution, climate change, deforestation, over population and a lot more . The direct environmental impacts of resource use include the degradation of fertile land, water shortages, waste generation, toxic pollution, and biodiversity loss in terrestrial and freshwater ecosystems. Renewable energy sources which are available in abundance all around us, provided by the sun, wind, water, waste, and heat from the Earth are replenished by nature and emit little to no greenhouse gases or pollutants into the air. The effects of climate change are quickly escalating due to excess greenhouse gasses in our atmosphere that are trapping in excess heat from the sun. A way to reduce emissions and save our planet would be to would be to change our energy sources and switch to renewable energy sources. Solar produces less life-cycle GHG emissions than conventional fossil fuel energy sources. While there may be some GHG emissions produced during the manufacturing and recycling of the solar system, the generation of energy results in zero GHG emissions and zero environmental impact.

Answer
Fossil fuels, such as coal, oil and gas, are by far the largest contributor to global climate change, accounting for over 75 percent of global greenhouse gas emissions and nearly 90 percent of all carbon dioxide emissions. These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth's orbit and levels of carbon dioxide (CO2). Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation. When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming. Already the average global temperature has increased by 10C.Climate change refers to long-term shifts in temperatures and weather patterns, mainly caused by human activities, especially the burning of fossil fuels. Renewable energy sources, such as wind and solar, emit little to no greenhouse gases, are readily available and in most cases cheaper than coal, oil or gas. The energy sector is the largest emitter of greenhouse gases into the atmosphere, contributing to climate change. In turn, changes in climate can disrupt energy networks themselves, stress infrastructure, and pose safety risks to people.Generating renewable energy creates far lower emissions than burning fossil fuels. Transitioning from fossil fuels, which currently account for the lion's share of emissions, to renewable energy is key to addressing the climate crisis. Although renewable energy sources produce relatively low levels of GHG emissions and conventional air pollution, manufacturing and transporting them will produce some emissions and pollutants. The production of some photovoltaic (PV) cells, for instance, generates toxic substances that may contaminate water resources.The biggest dark side of renewable energy is likely the amount of space it requires. Each solar farm can produce about 357,000 kWh per acre, but the United States' electricity uses around 4,000 billion kWh each year. So, that country would need to use 11 million acres to get all of our electricity from solar panels. Renewable energy sources generate most of their energy at certain times of the day. Its electricity generation does not match with the peak demand hours. The intermittency of sunshine and wind cannot provide an on-demand power source 24 hours a week. Solar energy and wind are unpredictable. While renewable energy waste may be composed of less toxic substances than fossil fuel by-products, they are still a hazard to the environment. There is increasing concern regarding what happens with these materials when they are no longer viable, especially since they are difficult to recycle. Although India has made progress in developing its renewable energy sector, it still faces obstacles. Off-taker risk, lack of infrastructure, lack of financial intermediaries, and lack of investor understanding are the top four challenges to overcome.

Is 12 years to convert the entire automotive sector to electromobility a long or short time?
Question
6 answers
  • Mar 31, 2023
Is 12 years to switch the entire automotive sector to electromobility a long or short time, considering both the currently available green technologies and eco-innovations in electromobility, hydrogen-powered vehicles, zero-emission production of hydrogen and other e-fuels, development of zero-emission energy sources, high recycling rates of electric vehicles, etc.?
Is it possible to shift the whole of motorisation in Europe to electromobility by 2035, i.e. to implement the European Union's plan under which, after 2035, no new combustion-engine cars will be registered and put into service, and only zero-emission vehicles, i.e. electric and hydrogen vehicles, will be registered?
By 2035, will there be a significant drop in the price and increase in the uptake of e-fuels, i.e. synthetic fuels produced from water or hydrogen extracted from the air in a production process powered by renewable and emission-free energy sources?
The green transformation of the automotive industry is one of the key components of the green transformation of the economy, with the aim of building a sustainable, zero-emission, green closed loop economy as quickly and efficiently as possible. A key objective of the green economy transition is to slow down and possibly halt accelerating global warming and reduce the scale of the global climate catastrophe, which, according to long-term climate change models, could already occur by the end of this 21st century. The green transformation of motoring is primarily about the development of electromobility and hydrogen-powered vehicles through the application of available green technologies and eco-innovations in the development of electromobility, hydrogen-powered vehicles, zero-emission production of hydrogen and other e-fuels, the development of zero-emission energy sources, a high level of recycling of electric vehicles, and the activation of this process through the increase of government subsidy programmes within the framework of green finance, the introduction of tax credits to mobilise business for green investment projects, the introduction of new pro-climate and pro-environmental regulations, etc. In order to activate pro-environmental business processes and to activate operators to join the green transformation of the economy, specific calendars for the said green transformation processes of the economy are enacted, including the pro-climate and pro-environmental transformation of the car, rail, river, sea and air transport sectors. In many countries of the world, the rail transport sector is already 100 per cent or mostly converted to electromobility. Other segments of transport are mostly dominated by vehicles, ships, aircraft powered by internal combustion engines that burn high-emission fossil fuels. So there is still a lot of work to be done on the green transformation of the various transport sectors. In March 2023, the European Union Parliament adopted a plan to restrict the purchase of internal combustion cars after 2035 as an important motivating factor for the development of electromobility, i.e. the development of emission-free motoring. An evaluation of the development of electromobility in the European Union and an assessment of the feasibility of this plan is to be carried out in three years' time. The following exception was added to earlier drafts of this regulation: synthetic fuels produced from, for example, water or hydrogen extracted from the air on the basis of zero-emission production of these fuels, i.e. by using electricity generated from renewable and zero-emission energy sources in the hydrogen production process. Such solutions for the production of e-fuels and their use in powering motor vehicles will be permitted in the European Union after 2035. In the government-controlled meanstream media in the country where I operate, there has been the usual misinformation about the European Union's climate policy. Under the current plan, it will not be possible to register a car with an internal combustion engine powered by petroleum refining derivatives. Well, the possibility of buying and registering cars with combustion engines will not necessarily be prevented after 2035, because it will not be economically viable to buy a new car with such an engine after the restrictions have been introduced. According to current forecasts of electromobility development, it will not be economical to buy an internal combustion car after 2035, because after 2035 these types of vehicles will be the most expensive due to additional punitive charges that will be imposed by the state on car companies that still want to produce these types of internal combustion vehicles. There will be no restrictions or limitations for the purchase of vehicles powered by e-fuels, i.e. synthetic fuels whose combustion process will be emission-free. Technologies for the production of e-fuels based on water, hydrogen drawn from the atmosphere, the process of producing these e-fuels using electricity from large-scale renewable and emission-free energy sources already exist, but are expensive for the time being. But as there is still more than a decade to go until 2035, so there is enough time to adequately refine these technologies and make them widespread so that they become much cheaper. A rapid decline in the price of these new green e-fuel technologies over the next few years is possible. In the past, an analogous process has occurred for other green technologies. For example, the cost of photovoltaic technologies has fallen by almost 99 per cent in the three decades to 2019. In addition, the scale of restrictions on driving in certain public places, mainly in city centres for internal combustion vehicles, will increase in the coming years. Already, more and more cities are closing their city centres to combustion cars, starting with restrictions on this issue for cars powered by diesel and manufactured many years ago, as such cars are the most polluting and emit toxic chemicals, toxic especially to children.
In view of the above, I address the following question to the Honourable Community of scientists and researchers:
By 2035, will there be a significant decrease in the price and increase in the uptake of e-fuel technologies, i.e. synthetic fuels produced from water or hydrogen extracted from the air in a production process powered by renewable and emission-free energy sources?
Is it possible to switch the whole of European motorisation to electromobility by 2035, i.e. to realise the European Union's plan under which, after 2035, no new cars with combustion engines will be registered and put into service, and only zero-emission vehicles, i.e. electric and hydrogen vehicles, will be registered?
Is 12 years a long or short time to convert the whole of the automotive sector to electromobility, given both the green technologies and eco-innovations currently available in electromobility, hydrogen-powered vehicles, zero-emission production of hydrogen and other e-fuels, development of zero-emission energy sources, high recycling rates for electric vehicles, etc.?

On what does the significantly differentiated level of energy prices across countries currently depend?
What are the key determinants of the widely varying level of energy prices across countries?
It used to be that this variation in energy prices from country to country largely depended on, among other things, the content in the earth's crust of the various types of fossil energy resources. Today, in the era of the Fourth Technological Revolution, in developed and developing economies, the key factors determining the level of energy prices include, among others, the current and/or strategic energy policies under which specific types of energy are developed. In some countries it is still mainly supported systemically, i.e. financially by the state mainly the development of dirty combustion energy and in other countries the development of emission-free energy, green energy based on renewable and emission-free energy sources. Systemic state support consists of supporting specific types of energy sources through financial support from the state's public finance system. Due to the system of CO2 emission fees introduced in the European Union, in countries that continue to develop mainly dirty combustion energy, energy prices will rise rapidly in the coming years. In contrast, in countries where renewable energy sources, including wind and solar power, are being rapidly developed, it is when the sun shines and the wind blows that carbon-free energy has produced surplus energy and there have been negative prices. An example of a country where in recent years the government has continued to support the development of dirty combustion energy and block the development of renewable energy sources is the country where I operate. Currently, before the next parliamentary elections, the government has frozen the increase in energy prices through the created instrument of subsidies from the state finance system. However, in view of the fact that still more than 3/4 of electricity and even more thermal energy is produced from burning coal and lignite, it is likely that in the next few years the already one of the highest energy prices (in relation to the income level of citizens, compared to Europe) will continue to rise in Poland. As a result, energy market analysts forecast that Poland may see a large increase in energy prices in 2024. In Poland, per 1 kWh of electricity produced, there are 700-750 gr of CO2 emitted into the atmosphere. By contrast, in Europe the average of this CO2 emission is 3 times lower. High energy prices in Poland are due not to the war in Ukraine as the government lies in the media controlled by it, but to the fact that the current PIS government for 8 years has been blocking and slowing down the development of renewable and emission-free energy sources through which eclectic energy can be produced more cheaply and emission-free. Carbon-free energy production does not involve incurring additional punitive fees established in the European Union as incentive instruments for the smooth implementation of the green transition in the energy sector.
In view of the above, I address the following question to the esteemed community of scientists and researchers:

Answer
According to Energy prices and costs in Europe, the variation in energy prices across countries depends on several factors:
  1. Supply and Demand: Like all commodities, energy prices are largely governed by the relationship between product supply and demand.
  2. Market Speculation and Geopolitical Events: These are the main drivers behind price development.
  3. Prices of Inputs: The prices of inputs can affect energy costs.
  4. Market Competition and Market Integration Conditions: The market competition level and market integration conditions can influence energy prices.
  5. Regulatory and Policy-Related Costs: Different regulations and policies can lead to different costs, affecting energy prices.
  6. Taxation: The level and type of taxation can also affect energy prices.
  7. Consumers’ Needs and Behavioural Patterns: Different needs and behaviors of consumers can lead to variations in energy prices.
It’s also worth noting that the impact of high energy prices can vary across countries due to different regulations, policy responses, market structures, and contracting practices.

Answer
All energy sources have some impact on our environment. Fossil fuels coal, oil, and natural gas do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions. Hydropower reservoirs often have multiple uses - providing drinking water, water for irrigation, flood and drought control, navigation services, as well as energy supply. Hydropower currently is the largest source of renewable energy in the electricity sector. Electricity from renewable energy sources produces between 90-99% less greenhouse gases (GHGs) compared with coal-fired plants and causes 70-90% less pollution. Focusing on renewable energy sources other than fossil fuels and coals might help in avoiding environmental impacts, specifically from air pollution and GHGs. When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming. Already the average global temperature has increased by 1C.

What are the characteristics of renewable energy and role of environmental manager in conservation of various resources and to preserve ecosystem?
Relevant answer
  • Sep 15, 2023
Answer
Renewable energy includes those types of energy that are obtained from natural sources. Therefore, their main characteristic is that they're unlimited and do not produce greenhouse gas emissions. Resources are characterized as renewable or nonrenewable; a renewable resource can replenish itself at the rate it is used, while a nonrenewable resource has a limited supply. Renewable resources include timber, wind, and solar while nonrenewable resources include coal and natural gas. Renewable energy is a critical solution in combating climate change. By transitioning to a low-carbon energy mix, we can reduce greenhouse gas emissions, improve energy security, and provide millions of people access to clean, reliable, and affordable energy. Renewable resources are considered especially important for their potential to replace non-renewable, or finite, resources in the production of energy. Additionally, renewable resources can offer cleaner energy solutions than those provided by non-renewable resources such as coal and fossil fuels. There are numerous benefits that come from energy efficiency as it regulates greenhouse gas emissions, which includes direct emission that comes from fossil fuel consumption and combustion. It also reduces all the indirect emissions from electricity generation as well. Environmental resources management aims to ensure that ecosystem services are protected and maintained for future human generations, and also maintain ecosystem integrity through considering ethical, economic, and ecological variables. Energy management is the proactive and systematic monitoring, control and optimization of an organization's energy consumption to conserve use and decrease energy costs. Energy management includes minor actions such as monitoring monthly energy bills and upgrading to energy-saving light bulbs.As an environmental manager you'll be responsible for overseeing the environmental performance of public, private, or even voluntary organizations and ensuring they're compliant with environmental regulations in air quality, waste, clean water, and pollution. Environmental management helps you identify degradation factors and implement strategies to mitigate them. It also helps you predict future impacts of environmental degradation and initiate processes to minimize the effects.Environmental managers plan and direct the development of management systems designed to minimize the impact of an organization on the environment. This includes the regulation and management of electricity, water, general waste consumption, and pollution or carbon emissions from road or air travel. Environmental conservation protects wildlife and promotes biodiversity. Maintaining a healthy and functional ecosystem helps prevent the extinction of certain animal species. If the environment is destroyed, some animals are forced out of their habitat, making it hard for them to survive elsewhere.

Answer
All energy sources have some impact on our environment. Fossil fuels coal, oil, and natural gas do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.Fossil fuels are the world's primary energy source, supplying four-fifths of the global energy mix in 2021. And while they are readily available and cheaper to produce, they also run on limited amounts, take long periods to replenish, and significantly contribute to global carbon emissions. The sun is the main source of energy on Earth. Other energy sources include coal, geothermal energy, wind energy, biomass, petrol, nuclear energy, and many more. Nearly all combustion byproducts have negative effects on the environment and human health: CO2 is a greenhouse gas, which contributes to the greenhouse effect. SO2 causes acid rain, which is harmful to plants and to animals that live in water. Coal, again, is the dirtiest fuel. It emits much more greenhouse gases than other sources – hundreds of times more than nuclear, solar, and wind. Oil and gas are also much worse than nuclear and renewable, but to a lesser extent than coal. Although renewable energy sources produce relatively low levels of GHG emissions and conventional air pollution, manufacturing and transporting them will produce some emissions and pollutants. The production of some photovoltaic (PV) cells, for instance, generates toxic substances that may contaminate water resources.The use of clean energy sources, such as water, wind, sunlight and nuclear, to generate electricity helps to reduce greenhouse gas emissions and mitigate climate change. This is because clean energy sources don't emit any greenhouse gases, such as carbon dioxide, during the electricity generating process. Wind energy has the lowest carbon footprint of all energy types. On a life-cycle basis, onshore wind emits 11 and offshore wind emits 12 grams of CO2 equivalent per kWh of electricity produced. The direct environmental impacts of resource use include the degradation of fertile land, water shortages, waste generation, toxic pollution, and biodiversity loss in terrestrial and freshwater ecosystems.

Answer
Solar energy is the most abundant of all energy resources and can even be harnessed in cloudy weather. The rate at which solar energy is intercepted by the Earth is about 10,000 times greater than the rate at which humankind consumes energy. Sunlight is one of our planets most abundant and freely available energy resources. The amount of solar energy that reaches the earth's surface in one hour is more than the planet's total energy requirements for a whole year.. One of the most important sources of energy is the sun. The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar cells.Electrical energy is the most convenient form of energy for most human uses. Electrical energy is easy use and move from one location to another, but it is almost impossible to store in any large quantity. It can be used for running computers and most appliances, home heating, and even transportation. Electrical energy is one of the most commonly used forms of energy in the world. It can be easily converted into any other energy form and can be safely and efficiently transported over long distances. As a result, it is used in our daily lives more than any other energy source. Environmental and economic benefits of using renewable energy include: Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. If we could replace fossil fuels with abundant renewable energy, we would cut energy prices, reduce emissions and lower the future risks of climate change, including the impact on food production. Despite the negative impact on wildlife, renewable energy still positively impacts the climate and the air. It fosters a stronger ecosystem because it is clean. The production of this electricity also has no impact on the environment. Unlike fossil fuels, renewable energy creation doesn't harm the ecosystem. Solar, wind, hydroelectric, biomass, and geothermal power can provide energy without the planet-warming effects of fossil fuels. In any discussion about climate change, renewable energy usually tops the list of changes the world can implement to stave off the worst effects of rising temperatures.

Answer
Fossil fuels coal, oil, and natural gas do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions. The environmental impacts related to energy production include climate change, acidification, impacts on waterways, and waste production. The industry is making active efforts to reduce environmental impacts. Switching to clean sources of energy, such as wind and solar, thus helps address not only climate change but also air pollution and health. The burning of fossil fuels results in the emission of significant quantities of carbon dioxide, a greenhouse gas, into the atmosphere. These gases have the ability to trap heat in the atmosphere, which ultimately leads to global warming. Biomass also results in the generation of harmful gases. Problems with energy supply and use are related not only to global warming that is taking place, due to effluent gas emission mainly CO2⁠, but also to environmental concerns such as air pollution, acid precipitation, ozone depletion, forest destruction, and emission of radioactive substances. Clean energy technologies improve human health by reducing air pollution and water and soil contamination. A clean energy economy will lower rates of asthma, heart conditions, and other health issues related to climate change across the nation. Using renewable energy can lead to several social impacts, including poverty elimination, climate change mitigation, and improving health by reducing pollution associated with gas emissions. Wind energy is one of the most sustainable forms of energy currently available. It harnesses the power of naturally moving air to spin wind turbines, which in turn generate electricity. Not only is this great because it provides a regenerative form of energy, but it also does so without greenhouse gas emissions. Harnessing power from the wind is one of the cleanest and most sustainable ways to generate electricity as it produces no toxic pollution or global warming emissions. Wind is also abundant, inexhaustible, and affordable, which makes it a viable and large-scale alternative to fossil fuels.

Answer
Natural sources such as solar, wind, tidal and geothermal have the potential to create far more energy than the world currently needs. The raw energy sources that Jacobson found to be the most promising are, in order, wind, concentrated solar, geothermal, tidal, solar photovoltaics wave, and hydroelectric. Hydrogen has the best chance of being widely used in the future. Sources of hydrogen are plentiful, it has many uses, and most of the needed technology has already been developed. Solar energy is the most promising source of energy fifty years from now. There are two types of energy: the first is renewable, and the second is non-renewable. Nature can replenish renewable resources for instance, solar energy. Solar energy is the energy obtained from the sun. As these sources of energy are renewable, they are also inexhaustible. More importantly, they cause little to zero climate or environmental damage. Fossil fuels, such as oil, coal, and natural gas, on the contrary, are available in finite quantities only. One of the promising future energy sources is biomass and biomass-derived resources and fuels such as biogas, biofuel, and algae. Hydrogen and methane gas hydrates will be important energy sources too. First of all, it is never going to end, we can use them for a long time and various purposes. Also, they generate energy in a large amount and efficiently. The most important benefit of renewable energy is that it is eco-friendly and don't contribute to environmental pollution. We depend most on fossil fuels for many energy uses because fossil fuels can be burnt, shipped and stored. The energy from fossil fuels is both concentrated and portable. Fossil fuel releases tremendous amount of energy on burning. Natural gas provides cleaner burning and coal is available in abundance. Mostly because of the low prices of obtaining they and their large quantities all around the world and fossil fuels are our primary energy resource because it is abundant and is relatively cheap to obtain. Fossil fuels are limited in the nature and can be exhausted very soon by human activities. So fossil fuels are called exhaustible natural resources. According to Odometers, we will run out of oil in 47 years, natural gas in 52 years, and coal in 133 years. In the long term, if we want to use energy sources that will never run out, there are better alternatives than fossil fuels. There is no definitive answer to the question of which renewable energy resource is the most promising for the future of our planet, as different resources have different advantages and disadvantages depending on various factors such as location, availability, cost, performance, environmental impact, social acceptance. Geothermal energy is the heat produced deep in the Earth's core and a renewable resource that generates electricity with minimal carbon emissions.

Can renewable energy reduce climate change and how is Earth's climate related to energy?
Relevant answer
  • Sep 12, 2023
Answer
Renewable energy can play a significant role in reducing climate change, as it is closely linked to the Earth's climate through the greenhouse gas effect and the energy sector's contribution to greenhouse gas emissions.
  1. Greenhouse Gas Emissions: The burning of fossil fuels such as coal, oil, and natural gas for energy production is a major source of greenhouse gas emissions, particularly carbon dioxide (CO2). These emissions trap heat in the Earth's atmosphere, leading to the greenhouse effect and global warming, which is a key driver of climate change. Renewable energy sources, such as solar, wind, hydroelectric, and geothermal power, produce electricity without emitting significant greenhouse gases, making them a cleaner alternative to fossil fuels.
  2. Mitigating Climate Change: By shifting to renewable energy sources and reducing reliance on fossil fuels, we can significantly decrease greenhouse gas emissions. This transition can help mitigate the impacts of climate change, such as rising temperatures, sea-level rise, extreme weather events, and disruptions to ecosystems. Renewable energy technologies offer a way to generate electricity and heat more sustainably and with lower carbon emissions.
  3. Energy Efficiency: Another important aspect of the relationship between energy and climate change is energy efficiency. Using energy more efficiently reduces the amount of energy required to perform various tasks, which in turn reduces greenhouse gas emissions. Energy efficiency measures, such as better insulation, efficient appliances, and transportation technologies, can help lower energy demand and, consequently, emissions.
  4. Renewable Energy's Potential: The growth of renewable energy capacity worldwide can help decouple economic growth from greenhouse gas emissions. As renewable energy technologies become more affordable and accessible, they can provide a reliable and sustainable energy supply while reducing the carbon footprint associated with energy production.
  5. Policy and Innovation: Governments, businesses, and individuals all have roles to play in the transition to renewable energy. Policy measures, such as carbon pricing, subsidies for renewable energy, and regulations that limit emissions, can incentivize the adoption of clean energy technologies. Additionally, ongoing innovation and research in renewable energy can further improve its efficiency and reduce costs.
In summary, renewable energy can reduce climate change by lowering greenhouse gas emissions associated with energy production and consumption. The Earth's climate is closely tied to energy through the emissions of greenhouse gases, and a shift toward renewable energy sources is a critical step in mitigating climate change and creating a more sustainable energy future.

Answer
Dear Doctor
I quoted the following from web hoping of benefit.
"For renewable energy technology to be a global public good - meaning available to all, and not just to the wealthy - it will be essential to remove roadblocks to knowledge sharing and technological transfer, including intellectual property rights barriers.
Essential technologies such as battery storage systems allow energy from renewables, like solar and wind, to be stored and released when people, communities and businesses need power. They help to increase energy system flexibility due to their unique capability to quickly absorb, hold and re-inject electricity, says the International Renewable Energy Agency.
Moreover, when paired with renewable generators, battery storage technologies can provide reliable and cheaper electricity in isolated grids and to off-grid communities in remote locations.
A robust supply of renewable energy components and raw materials is essential. More widespread access to all the key components and materials - from the minerals needed to produce wind turbines and electricity networks, to electric vehicles - will be key.
It will take significant international coordination to expand and diversify manufacturing capacity globally. Moreover, greater investments are needed to ensure a just transition - including in people’s skills training, research and innovation, and incentives to build supply chains through sustainable practices that protect ecosystems and cultures."

Can the world reach a 100% renewable energy system by or before 2050 and what is the fastest growing renewable energy in the world?
Relevant answer
  • Sep 10, 2023
Answer
Several studies have proven that 100% renewable energy systems can be achieved on global, regional, and national levels by or before 2050. The number of published studies has grown by 27% annually since the year 2010 and continues to grow each year. By 2050, we could get all the energy we need from renewable sources. This report shows that such a transition is not only possible but also cost-effective, providing energy that is affordable for all and producing it in ways that can be sustained by the global economy and the planet. Power the world with 100% renewable energy. The answer given by most of the researchers to this question is a big YES. Such an energy system has economical as well as environmental benefits. Renewable energy, while becoming more cost-competitive, still cannot match the affordability and reliability of fossil fuels. In many developing countries, the infrastructure and resources required for renewable energy are not yet in place, making it difficult to transition away from fossil fuels. EIA projects that total world electricity generation will reach nearly 45 trillion kilowatthours (kWh) by 2050, almost 20 trillion kWh more than the 2018 level. Although growth occurs in both OECD and non-OECD regions, the growth in electricity demand in non-OECD regions far outpaces those in OECD regions. The country boasts one of the largest manufacturing ecosystems for wind energy and is experiencing rapid growth in solar capacity, propelling India to be the global leader in renewable energy. First on our list of the fastest-growing renewable energy sources, hydropower is the most widely used form of renewable energy in the world, producing 1 295 gigawatts of energy. This amounts to 54% of the global renewable power generation capacity. The most common hydropower comes from water in dams. Solar photovoltaics are the fastest growing electricity source.The world can reach a 100% renewable energy system by or before 2050. Sustainability - A new energy system would be mainly based on solar and wind energy, energy storage, sector coupling, and direct and indirect electrification of almost all energy demand. Solar photovoltaics are the fastest growing electricity source. In 2020, around 139 GW of global capacity was added, bringing the total to about 760 GW and producing almost 3 percent of the world's electricity. Biofuels are both shown separately and are included in petroleum and other liquids. In our Annual Energy Outlook 2022 (AEO2022) Reference case, which reflects current laws and regulations, we project that the share of U.S. power generation from renewables will increase from 21% in 2021 to 44% in 2050. Fast Transition' scenario, shows a realistic possible future for a fossil-free energy system by around 2050, providing 55% more energy services globally than today, by ramping up solar, wind, batteries, electric vehicles, and clean fuels such as green hydrogen (made from renewable electricity).

Should renewable energy replace fossil fuels and why is the management of renewable resources so important?
Relevant answer
  • Sep 9, 2023
Answer
According to different sources, renewable energy can be replenished by natural processes and will not run out, unlike fossil fuels, which are finite and non-renewable. Renewable energy sources include solar, wind, hydro, geothermal, and biomass. Fossil fuels include coal, oil, and natural gas.
There are many reasons why renewable energy should replace fossil fuels. Here are some of them:
  • Renewable energy is cleaner and greener than fossil fuels. Burning fossil fuels produces carbon dioxide and other greenhouse gases that cause global warming and climate change. Renewable energy sources emit little or no greenhouse gases, reducing air pollution and environmental damage.
  • Renewable energy is more cost-effective than fossil fuels in the long run. Although renewable energy projects may have high initial capital costs, they have low operating and maintenance costs and can generate electricity for free or at a low price once installed. Fossil fuels, on the other hand, have high extraction, transportation, and environmental costs that are not reflected in their market prices.
  • Renewable energy is more secure and reliable than fossil fuels. Fossil fuels are subject to geopolitical conflicts, price fluctuations, and supply disruptions that can affect the stability and affordability of energy. Renewable energy sources are widely distributed and can provide local and decentralized power generation that reduces dependence on imports and enhances energy resilience.
Managing renewable resources is very important because it ensures that they are used sustainably and efficiently to meet humanity's current and future needs. Renewable resources are not unlimited and can be degraded or depleted if they are overexploited or mismanaged. For example, hydropower can affect water quality and quantity, biodiversity, and ecosystem services if dams are not properly designed and operated. Biomass can contribute to deforestation, soil erosion, and air pollution if not harvested from sustainable sources.
Therefore, managing renewable resources requires careful planning, monitoring, evaluation, and adaptation to balance exploitation demands with respect for regenerative capacities. It also involves the participation of various stakeholders, such as governments, businesses, communities, and consumers, to ensure that the benefits and costs of renewable energy are equitably distributed and that the social and environmental impacts are minimized.

Answer
India is also embracing the power of renewable energy. It has already announced its aim to reach net zero emissions by 2070. Furthermore, according to the Ministry of Power, the country is likely to meet 62% of its electricity requirements with 500 GW of non-fossil fuel sources by 2030. India has set a target to reduce the carbon intensity of the nation's economy by less than 45% by the end of the decade, achieve 50 percent cumulative electric power installed by 2030 from renewable, and achieve net-zero carbon emissions by 2070. India aims for 500 GW of renewable energy installed capacity by 2030. Renewable energy in the future is predicted that by 2024, solar capacity in the world will grow by 600 gigawatts (GW), almost double the installed total electricity capacity of Japan. Overall, renewable electricity is predicted to grow by 1 200 GW by 2024, the equivalent of the total electricity capacity of the US. By relying on clean, renewable sources of energy, such as solar and wind power, we can reduce our dependence on fossil fuels and decrease the amount of harmful pollutants like carbon dioxide that are emitted into the atmosphere. First of all, it is never going to end, we can use them for a long time and various purposes. Also, they generate energy in a large amount and efficiently. The most important benefit of renewable energy is that it is eco-friendly and don't contribute to environmental pollution. New resources that are being researched or developed include hydrogen, nuclear fusion, ocean thermal energy conversion, and tidal and wave energy. One fuel that has the potential of being widely used in the future is hydrogen gas (H2). The country boasts one of the largest manufacturing ecosystems for wind energy and is experiencing rapid growth in solar capacity, propelling India to be the global leader in renewable energy. Renewable energy supplies reduce the emission of greenhouse gases significantly if replaced with fossil fuels. Since renewable energy supplies are obtained naturally from ongoing flows of energy in our surroundings, it should be sustainable.

Can the world run on renewable energy and why renewable energy is harder in India than in other countries?
Relevant answer
  • Sep 8, 2023
Answer
Yes, we have enough materials to power the world with renewable energy. We won't run out of key ingredients for climate action, but mining comes with social and environmental ramifications. Powering the world with renewable energy will take a lot of raw materials. The triad of “usual” challenges of renewable remains in India, such as (1) intermittency/variability; (2) location-specific potential (concentrated in areas sometimes away from consumers or the grid; and (3) higher costs. Attempting clean energy transition at the scale that India requires faces many challenges. These include access to affordable financing, lack of institutions that can deploy financing effectively in new low-carbon growth areas and technology risks. In terms of installed capacity, solar and hydropower are currently the leading sources of renewable energy in India. With an installed capacity of more than 52 gigawatts, India is among the world leaders in cumulative hydropower capacity. While renewable energy costs have decreased significantly over the years, initial capital investments remain high. Additionally, the livelier cost of electricity (LCOE) for renewable must be competitive with fossil fuels to encourage broader adoption. India is different because its grid is very weak and unstable, and instead of having a reasonable reserve margin (typically 15-20 percent in the west), there is a shortfall in the grid, officially in the range of 5 percent or so, but actually much higher.The intermittency of sunshine and wind cannot provide an on-demand power source 24 hours a week. Solar energy and wind are unpredictable. There is volatility in generation and volatility in loads. Energy generation by the burning of fossil fuels is more consistent. We know that change in climatic conditions is the major cause of concern in today's era. Most of the countries including India produce electricity from non-renewable resources like coal. Today nearly 61% of the nation’s electricity is produced by coal, which definitely increases environmental concerns. Factors influencing economic and financial barriers are high initial capital, lack of financial institutes, lack of investors, competition from fossil fuels, and fewer subsidies compared to traditional fuel. These factors have prevented renewable energy from becoming widespread.

Yes, India can meet 50 percent of its energy needs from renewable energy by 2030. Renewable energy sources have a combined installed capacity of 150+ GW. As of 31st August 2022, Renewable energy sources, including large hydropower, have a combined installed capacity of 163 GW. As its commitment to combat climate change and reduce global warming, India aims to achieve 500 GW of renewable energy by 2030, which will include 140 GW from wind energy and 280 GW from solar. The White House set out a target of 80% renewable energy generation by 2030 and 100% carbon-free electricity five years later. With 79% of total U.S. energy production still coming from fossil fuel sources as of 2021, achieving this goal will require billions of dollars in investments. Increasing renewable capacity to 500 GW by 2030, Meeting 50% of energy requirements from renewable, reducing cumulative emissions by one billion tonnes by 2030, and. reducing emissions intensity of India's gross domestic product (GDP) by 45% by 2030. Coal is the country's top energy source with a share of 46% in 2022, followed by oil (24%) and biomass (20%). Natural gas covers 5% and primary electricity (hydro, nuclear, solar, and wind) 4%.India is also embracing the power of renewable energy. It has already announced its aim to reach net zero emissions by 2070. Furthermore, according to the Ministry of Power, the country is likely to meet 62% of its electricity requirements with 500 GW of non-fossil fuel sources by 2030.

Answer
To achieve zero emissions, we'll need to increase the number of renewable energy sources, while ensuring excellent control of the power system. We'll also need to educate end consumers (industry, campuses, hospitals, homes) about the benefits of using RES, both for them and for the ecosystem.
One of the policies being developed and deployed by certain countries is demand response (DR), which ensures good grid management and offers cost advantages to customers, as well as the diminishing view of renewable energy sources, making it easier for private individuals to install them, thus avoiding the cost of the carbon charge.

Answer
In case battery capacity and renewable plant capacity are properly matched, batteries can sink the energy currently not needed and source that energy in case of missing capacity from the renewable power source.
This way, yield rates regarding energy taken from the plant increase and supply stability increases as well.
The challenge is finding a sweet spot between battery capacity and system cost.
As an example from personal experience:
Combining a solar array of 10kWpeak and a battery storage of 7.5kWh can get you to 95% autonomy from April to September in Europe.
Over the whole year, still 70% can be achieved.
A larger battery won't help as the drop comes in December/January when the PV isn't sufficient to power the installation, even less so to charge the battery.
Doubling the PV-capacity would help but becomes unreasonably expensive.
Adding a small windmill would be great as typically this would generate more power in winter.

Answer
Switching to clean sources of energy, such as wind and solar, thus helps address not only climate change but also air pollution and health. They differ from fossil fuels principally in their diversity, abundance and potential for use anywhere on the planet, but above all in that they produce neither greenhouse gases which cause climate change nor polluting emissions. It is evident that clean energy is less harmful and often cheaper. India is aiming to attain 175 GW of renewable energy which would consist of 100 GW from solar energy, 10 GW from bio-power, 60 GW from wind power, and 5 GW from small hydropower plants by the year 2022. India faces three principal challenges: (1) how to expand reliable energy access and use while maintaining affordability for consumers and financial stability for the DISCOMs; (2) how, at the same time, to integrate increasing shares of renewable energy in a secure and reliable manner; and (3) how to reduce emissions. Environmental and economic benefits of using renewable energy include: Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. By relying on clean, renewable sources of energy, such as solar and wind power, we can reduce our dependence on fossil fuels and decrease the amount of harmful pollutants like carbon dioxide that are emitted into the atmosphere. Renewable energy is no exception, and each source has its own trade-offs. However, the advantages over the devastating impacts of fossil fuels are undeniable: from the reduction of water and land use, less air and water pollution, less wildlife and habitat loss, to no or lower greenhouse gas emissions. Although India has made progress in developing its renewable energy sector, it still faces obstacles. Off-taker risk, lack of infrastructure, lack of financial intermediaries, and lack of investor understanding are the top four challenges to overcome.

Will renewable energy sources somehow stop global warming and renewable energy is important in energy and environmental sustainability?
Relevant answer
  • Aug 31, 2023
Answer
Renewable energy is energy produced from sources like the sun and wind that are naturally replenished and do not run out. Renewable energy can be used for electricity generation, space and water heating and cooling, and transportation. Sustainable energy, such as wind and solar energy, creates zero carbon emissions that can harm the atmosphere and contribute to global warming. It offsets the need for fossil fuels, which are actively increasing climate change and polluting our earth. We should use energy efficiency technologies (less energy use), use greening transportation means more efficient mass transportation systems, promote the use of renewable means natural source of energy (solar, wind, geothermal, etc) and reduces our use of fossil fuels especially carbon-intensive coals to reduce climate effects.Not only do they improve our health and economy, but also the environment. Using renewable energy over fossil fuels has a number of advantages. The most important advantage of renewable energy is that it puts an end to the production of greenhouse gases, most notably CO2 that causes global heating. Cheap electricity from renewable sources could provide 65 percent of the world's total electricity supply by 2030. It could decarbonize 90 percent of the power sector by 2050, massively cutting carbon emissions and helping to mitigate climate change. Derived from natural resources that are abundant and continuously replenished, renewable energy is key to a safer, cleaner, and sustainable world. Environmental and economic benefits of using renewable energy include: Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. Renewable energy sources such as solar, wind, hydro, geothermal, and biomass can significantly contribute to sustainable development. We can reduce our reliance on finite and non-renewable resources like fossil fuels by harnessing these energy sources. They differ from fossil fuels principally in their diversity, abundance and potential for use anywhere on the planet, but above all in that they produce neither greenhouse gases which cause climate change nor polluting emissions.

Shyam Lakshmanan Thank you for the insights. You rightly wrote, "EV's are another area of concern. As long as electricity generated is not green (or net zero), it does not address the global warming issue. Furthermore...". This is precisely The Paradox of EVs. Excerpts from: https://www.smartgreenpost.com/2021/10/06/the-paradox-of-electric-cars/ ".. one of the buzzwords if you will, is electric cars. This could be a good start, or just a way of hiding behind a finger, clearing one’s conscience, and perhaps saying that one has done everything possible to avoid the climate disaster we are heading for. For two reasons.
The first is linked to a simple numerical statement: if you want to talk about a plan to tackle climate change, you have to take into account all human activities that cause greenhouse gas emissions: according to the latest estimates (IPCC data: https://www.epa.gov/ghgemissions/global-greenhouse-gas-emissions-data) focusing on cars means, at best, acting on about 8% of global greenhouse gas emissions. Very, very little. At the top of the list, though decidedly against our perception, are agriculture, livestock farming and industrial power generation.
The second reason is linked to the failure to address the choice of electric cars with an integrated and supply chain strategy: it is true that these cars are powered by electricity, but most of this energy is still derived from power plants that are (still) based on coal"....

Which renewable energy source is growing fastest and what is the largest energy source used in India and future trends in renewable energy?
Relevant answer
  • Aug 22, 2023
Answer
Solar and hydropower are currently the leading sources of renewable energy in India. With an installed capacity of more than 52 gigawatts, India is among the world leaders in cumulative hydropower capacity.Wind and solar are the fastest growing renewable sources, but contribute just 5% of total energy used in the U.S. In India Solar Power: 67.07 GW. Biomass/Co-generation: 10.2 GW. Small Hydro Power: 4.94 GW. Waste To Energy: 0.55 GW. Hydropower currently is the largest source of renewable energy in the electricity sector. It relies on generally stable rainfall patterns, and can be negatively impacted by climate-induced droughts or changes to ecosystems which impact rainfall patterns. Thermal power is the "largest" source of power in India. There are different types of thermal power plants based on the fuel used to generate the steam such as coal, gas, and Diesel, natural gas. About 71% of electricity consumed in India is generated by thermal power plants. Over 80%of India's energy needs are met by three fuels: coal, oil and solid biomass. Coal has underpinned the expansion of electricity generation and industry, and remains the largest single fuel in the energy mix. India has emerged as a major player in the global energy market, with the country ranking third in the world for primary energy consumption, according to the India Energy Outlook 2021 report by the International Energy Agency (IEA). Fossil fuels are the largest sources of energy for electricity generation. Businesses and industries are moving towards renewable energy to reduce emissions, lower energy costs, and improve eco-friendliness. The major renewable energy trends include digitization, energy-efficient integrations, and solutions that overcome the intermittency in renewable energy production. Renewable energy has become increasingly important as more people have concerns about climate change. Trends across the industry include domestic production and the growing importance of storage. Production capacity is set to continue accelerating over the next few years. India is also embracing the power of renewable energy. It has already announced its aim to reach net zero emissions by 2070. Furthermore, according to the Ministry of Power, the country is likely to meet 62% of its electricity requirements with 500 GW of non-fossil fuel sources by 2030. Built on a survey of 216 power sector stakeholders, the 2022 Megatrends in Power report examines four megatrends that are setting the stage for the next decade of a rapidly evolving energy ecosystem: Decarbonization. Electrification. Climate Adaptation. Prior to the global pandemic, India's energy demand was projected to increase by almost 50% between 2019 and 2030, but growth over this period is now closer to 35% in the STEPS, and 25% in the Delayed Recovery Scenario. At present Indian Power Plants installed capacity is 404 GW and 58% as fossil power plants and by 2030, the requirements of total power would be expected as 817 GW, almost double.

What renewable energy source does India use the most and who is the largest consumer of renewable energy in the world?
Relevant answer
  • Aug 21, 2023
Answer
In 21 states, there are 41 solar parks with a cumulative capacity of more than 26,144 MW that have already been approved by the MNRE. The Kurnool solar park was set up with 1000 MW; and with 2000 MW the largest solar park of Pavagada is currently under installation. Over 80%of India's energy needs are met by three fuels: coal, oil and solid biomass. Coal has underpinned the expansion of electricity generation and industry, and remains the largest single fuel in the energy mix. Hydroelectric energy is by far the most prevalent, accounting for 83 percent of the world's electricity generation from renewable sources. This is most likely because the requisite technology to generate electricity by harnessing the flow of water has been around the longest, dating back to the early 20th century. Solar Power: 67.07 GW. Biomass/Co-generation: 10.2 GW. Small Hydro Power: 4.94 GW. Waste To Energy: 0.55 GW. As its commitment to combat climate change and reduce global warming, India aims to achieve 500 GW of renewable energy by 2030, which will include 140 GW from wind energy and 280 GW from solar. Coal is the country's top energy source with a share of 46% in 2022, followed by oil (24%) and biomass (20%). Natural gas covers 5% and primary electricity (hydro, nuclear, solar, and wind) 4%. The ten countries with the most renewable energy are Iceland, Norway, Sweden, Brazil, New Zealand, Denmark, Austria, Switzerland, Finland, and Colombia. Iceland is the country with the most renewable energy, reporting that 86.87% of its energy comes from renewable sources. At present, wind power is the most efficient method of sustainable energy production. In fact, it's more than twice as efficient as its closest competitor (geothermal). India is also embracing the power of renewable energy. It has already announced its aim to reach net zero emissions by 2070. Furthermore, according to the Ministry of Power, the country is likely to meet 62% of its electricity requirements with 500 GW of non-fossil fuel sources by 2030. Hydropower currently is the largest source of renewable energy in the electricity sector. It relies on generally stable rainfall patterns, and can be negatively impacted by climate-induced droughts or changes to ecosystems which impact rainfall patterns. China consumes by far the most electricity of any country in the world, with more than 7.8 terawatt-hours consumed in 2021. The United States ranked as the second-leading electricity consumer that year, with nearly 4,000 terawatt hours consumed. Industry is the main consumer of gas with 52% in 2022 (mainly fertilizer plants). It is followed by electricity production (21%) and, to a much lesser extent, transport (5%) and the residential and services sector (6%). Solar PV installations will continue to break new records, with annual additions forecast to reach over 160 GW by 2022. That would be almost 50% higher than the level achieved in 2019 prior to the pandemic, affirming solar's position as the “new king” of global electricity markets.

  • Aug 21, 2023
Answer
If we want humanity to survive longer than non-renewable energy sources, then we certainly need to stop pollution and global warming. The difference is even greater if we look at the pollution of coal vs solar energy. Coal is the most polluting fossil fuel on Earth, meanwhile, solar energy is not polluting at all. Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs. Producing and burning fossil fuels creates air pollution that harms our health and generates toxic emissions that drive climate change. From the electricity that lights our homes to the cars we drive to work, modern life was built on fossil fuels like coal, oil and natural gas. Environmental and economic benefits of using renewable energy include: Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. Coal, again, is the dirtiest fuel. It emits much more greenhouse gases than other sources hundreds of times more than nuclear, solar, and wind. Oil and gas are also much worse than nuclear and renewable, but to a lesser extent than coal.Unlike natural gas and coal, we can't store up wind and sunshine to use when we need to make more electricity. If the wind doesn't blow or the sun hides behind clouds, there sometimes isn't enough power for everyone. Fossil fuels cannot be replenished by natural means at the same rate that it is consumed that's why they are known as non-renewable sources of energy. Renewable energy sources are incredibly important because they don't emit the greenhouse gases that contribute to global warming and climate change. Non-renewable energy comes from sources that will eventually run out and can't be replenished in our lifetimes. Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution and diversifying energy supply and reducing dependence on imported fuels and creating economic development and jobs in manufacturing, installation, and more. These sources create particle pollution and other carcinogens that endanger health. Decades of research show that burning fuels or materials to produce electricity creates pollutants that trigger asthma attacks and heart attacks, cause cancer, shorten lives and other harmful health impacts.Non-renewable energy resources are available in limited supplies, usually because they take a long time to replenish. The advantage of these non-renewable resources is that power plants that use them are able to produce more power on demand. The non-renewable energy resources are: Coal.Renewables can effectively replace fossil fuels, creating crucial environmental, social and economic benefits. Global dependence on oil, natural gas and coal–and the damage this dependence inflicts–is well documented. But a transition away from fossil fuels is in progress and simply needs to be expedited.

Practical ways of applying Piezoelectricity in renewable enegy?
Question
1 answer
  • Aug 20, 2023
Additional application of Piezoelectricity in renewable energy would be a huge step towards the growing industry. Is there any possibility or possible combinations of existing renewable energy along with piezoelectricity?
Relevant answer
  • Aug 21, 2023
Answer
Piezoelectricity is a phenomenon in which certain materials generate electric charges when subjected to mechanical stress, such as pressure or vibration. This property can be harnessed for practical applications in renewable energy. Here are some ways piezoelectricity can be applied in renewable energy technologies:
  1. Vibration Energy Harvesting: Piezoelectric materials can convert mechanical vibrations, such as those generated by machinery, vehicles, or even human movement, into electrical energy. These materials can be integrated into structures to capture ambient vibrations and convert them into usable power for small electronic devices or sensors.
  2. Footfall Energy Harvesting: Piezoelectric flooring or walkways can generate electricity from the mechanical energy generated by footsteps. This concept can be used in high-traffic areas like airports, train stations, and malls to capture the energy generated by people walking.
  3. Roadway Energy Generation: Piezoelectric materials embedded in roadways or highways can generate electricity as vehicles pass over them. This concept, known as "piezoelectric roads," can help capture energy from the mechanical energy of moving vehicles.
  4. Structural Health Monitoring: Piezoelectric sensors embedded in structures like bridges and buildings can monitor vibrations and stress. The energy generated by these sensors can be used to power the monitoring system itself, reducing the need for external power sources.
  5. Underwater Energy Harvesting: Piezoelectric materials can be used to capture energy from water currents, ocean waves, and tides. This energy can be harnessed to power remote sensors, buoys, and other devices in marine environments.
  6. Wind Energy: Some piezoelectric materials can be integrated into wind turbine blades to capture the vibrations caused by wind gusts. This additional energy can supplement the power generated by the turbine.
  7. Wearable Energy Harvesting: Wearable devices, such as smartwatches and fitness trackers, can incorporate piezoelectric materials to generate power from the wearer's movements and body heat.
  8. Structural Integration: Piezoelectric materials can be integrated into various structures, such as buildings and bridges, to generate electricity from mechanical stresses caused by wind, vibrations, or other external forces.
  9. Powering Remote Sensors: Piezoelectric materials can be used to power sensors in remote or hard-to-reach locations, eliminating the need for frequent battery replacement or external power sources.
  10. Energy Storage: Piezoelectric materials can be used in conjunction with energy storage systems to capture and store energy from intermittent sources like wind and vibrations.
It's important to note that while piezoelectricity offers the potential for energy harvesting, the efficiency of these systems and the amount of energy generated can be influenced by factors such as the type of material used, the amount of mechanical stress applied, and the design of the system. Research and development in this field continue to explore ways to optimize the conversion efficiency of piezoelectric devices for practical renewable energy applications.

Answer
Hydropower currently is the largest source of renewable energy in the electricity sector. It relies on generally stable rainfall patterns, and can be negatively impacted by climate-induced droughts or changes to ecosystems which impact rainfall patterns. Solar photovoltaics are the fastest growing electricity source.The amount of electricity generated by wind increased by 265 TWh in 2022 (up 14%), the second largest growth of all power generation technologies. Wind remains the leading non-hydro renewable technology, generating over 2 100 TWh in 2022, more than all the others combined.Wind energy Energy generated from the kinetic energy of moving air. Wind energy is the fastest growing major source of electricity in the world. Solar power is one of the cleanest forms of energy because it does not emit any greenhouse gases. It also produces no harmful by-products.Solar Power: 67.07 GW. Biomass/Co-generation: 10.2 GW. Small Hydro Power: 4.94 GW. Waste To Energy: 0.55 GW. Wind power has been the fastest growing energy source in the world since it became more cost-effective in the 1990s, though it has a long way to go to catch up with hydro power. It is generally believed that wind is the most efficient way to harness renewable energy. Because windmills can be placed in open areas also used for farming, they offer flexibility. Generally, rows of wind turbines are constructed along coastal areas where nothing can hinder the flow of wind.Global solar PV capacity is set to almost triple over the 2022-2027 period, surpassing coal and becoming the largest source of power capacity in the world. Hydrogen has the best chance of being widely used in the future. Sources of hydrogen are plentiful, it has many uses, and most of the needed technology has already been developed. Hydropower is the most widely-used renewable power source, with the global hydroelectric installed capacity exceeding 1,295GW, accounting for more than 18% of the world's total installed power generation capacity and more than 54% of the global renewable power generation capacity.Globally we get the largest amount of our energy from oil, followed by coal, gas, and then hydroelectric power. As we look at in more detail below “How much of global energy comes from low-carbon sources?” the global energy mix is still dominated by fossil fuels. They account for more than 80% of energy consumption. In the industrial sector, biomass makes up 98 percent of the renewable energy use with roughly 60 percent derived from biomass wood, 31 percent from biofuels, and nearly 7 percent from biomass waste.

Why are fossil fuels more widely used than solar energy and should we replace fossil fuels with renewable energy?
Relevant answer
  • Aug 21, 2023
Answer
While fossil fuels will run out in 50 years, renewable energy is here and will never run out. But fossil fuels are very easy to store, which unfortunately cannot be said of renewable energy sources. Nowadays there are some alternative energy storage technologies, but they are still in their infancy. Thus, solar energy is made financially viable by misguiding the people by leaving out storage battery cost; handicapping it with subsidies and concessions that are front loaded by the government, and forcing it on the industry and hapless discoms through state policy. Fossil fuels are much cheaper. The sun's energy will not run out for billions of years.The sun provides more than enough energy to meet the whole world's energy needs, and unlike fossil fuels, it won't run out anytime soon. As a renewable energy source, the only limitation of solar power is our ability to turn it into electricity efficiently and cost-effectively.The sun provides more than enough energy to meet the whole world's energy needs, and unlike fossil fuels, it won't run out anytime soon. As a renewable energy source, the only limitation of solar power is our ability to turn it into electricity efficiently and cost-effectively.Methods of generating electricity that don't rely on fossil fuels, like nuclear and hydroelectric generation, are also important parts of the system in many areas. However, fossil fuels are still the backbone of the electricity system, generating 64% of today's global supply. Despite recent reductions in the cost of solar panel technology, the upfront cost of installation remains high, which can be a barrier to adoption for many households and businesses. Renewable energy is certainly more sustainable than fossil fuels, as there is a finite amount of fossil fuels in the earth's crust. Fossil fuels are made from ancient biological matter that has been contained in a pressurized environment for hundreds of thousands of years. This is not a process we can recreate quickly. Using more renewable energy can lower the prices of and demand for natural gas and coal by increasing competition and diversifying our energy supplies. And an increased reliance on renewable energy can help protect consumers when fossil fuel prices spike. In it renewable energy surpasses fossil fuels for electricity generation shortly after 2030. Renewable energy then dominates electricity generation by the 2050s, but even with an outlook that stretches to the end of the century, electricity doesn't pass 60% of “final energy” use.Renewable energy can be solar, wind, hydro, geothermal, or biomass. On the other hand, fossil fuels can be natural gas, coal, and oil. Fossil fuels also emit CO2 when burned, contributing to greenhouse gasses and ultimately climate change. This is where lines can blur between energy sources.

Is nuclear energy a renewable energy source and which fuel has the least amount of environmental impact on Earth?
Relevant answer
  • Aug 21, 2023
Answer
Renewable energies are rightly considered an asset in the fight against climate change, as they only emit low levels of greenhouse gases. However, nuclear energy is also low-carbon energy, as it emits 4 times less CO2 than solar power, 2 times less than hydroelectricity, and the same amount as wind power. Nuclear fuels, such as the element uranium, are not considered renewable as they are a finite material mined from the ground and can only be found in certain locations. Electricity from renewable resources such as solar, geothermal, and wind generally does not contribute to climate change or local air pollution since no fuels are combusted. A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years. Most nonrenewable energy sources are fossil fuels: coal, petroleum, and natural gas. Carbon is the main element in fossil fuels. For this reason, the time period that fossil fuels formed (about 360-300 million years ago) is called the Carboniferous Period.Nuclear energy has advantages over renewable in terms of reliability, GHG emissions, land use and waste. Nuclear is far more reliable than renewable like wind and solar. Nuclear plants keep churning out energy even when the wind is not blowing, and the sun is not shining. Nuclear has the highest capacity factor of any other energy source, producing reliable, carbon-free power more than 92% of the time. Natural gas is a relatively clean burning fossil fuelthat burning natural gas for energy results in fewer emissions of nearly all types of air pollutants and carbon dioxide (CO2) than burning coal or petroleum products to produce an equal amount of energy. CNG or compressed natural gas is a smoke-free gas and does not spread pollution, and thus used in our vehicles. Therefore, CNG is considered as an eco-friendly fuel. Every year, nuclear-generated electricity saves our atmosphere from more than 470 million metric tons of carbon dioxide emissions that would otherwise come from fossil fuels. That's the same as taking nearly 100 million passenger vehicles off the road. Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels. Nuclear fission is nearly 8,000 times more efficient at producing energy than traditional fossil fuels. That's a considerable amount of energy density. Solar energy does not cause air pollution, water pollution, or greenhouse gases. It causes the least environmental problems in the process of its harnessing and utilization. It is the ultimate source of energy. Renewable energies are rightly considered an asset in the fight against climate change, as they only emit low levels of greenhouse gases. However, nuclear energy is also low-carbon energy, as it emits 4 times less CO2 than solar power, 2 times less than hydroelectricity, and the same amount as wind power.

Answer
Yes, solar power is a renewable and infinite energy source that creates no harmful greenhouse gas emissions – as long as the sun continues to shine, energy will be released. The carbon footprint of solar panels is already quite small, as they last for over 25 years. Solar energy is that produced by the Sun's light photovoltaic energy and its warmth solar thermal for the generation of electricity or the production of heat. Inexhaustible and renewable, since it comes from the Sun, solar energy is harnessed using panels and mirrors. Solar energy a clean sourceand no greenhouse gas emissions are released into the atmosphere when using solar panels to create electricity. And because the sun provides more energy than we'll ever need, electricity from solar power is an essential energy source in the move to clean energy production. As a renewable source of power, solar energy has an important role in reducing greenhouse gas emissions and mitigating climate change, which is critical to protecting humans, wildlife, and ecosystems. Solar energy can also improve air quality and reduce water use from energy production. Photovoltaic solar energy is a clean, renewable source of energy that uses solar radiation to produce electricity.A photovoltaic (PV) cell, commonly called a solar cell, is a no mechanical device that converts sunlight directly into electricity. Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy.Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic (PV) panel, commonly called a solar panel, contains PV cells that absorb the sun's light and convert solar energy into electricity. These cells, made of a semiconductor that transmits energy (such as silicon), are strung together to create a module. A typical rooftop solar panel has 30 modules. It has bright future in India because (a) many parts (regions) of the country received sunlight on 300 days annually and so it becomes possible to generate 20 MW solar energy per square kilometer in such areas. (b) It is easy to established solar plants in urban and rural areas. Additionally, the government of India has set a target of achieving 175 GW of renewable energy capacity by 2022, with 100 GW of this coming from solar energy. The Indian government has implemented several policies and initiatives to encourage the development and use of solar energy in the country. Solar Energy has a bright future in India. Being a tropical country, India has an abundance of sunlight. Hence, there are huge possibilities of tapping solar energy. Solar energy is a non-conventional source of energy, but it is gaining popularity in rural and remote areas whose households' dependence on firewood and dung cakes is reduced as a result.Solar power is a fast developing industry in India. The country's solar installed capacity was 70.01 GWAC as of 30 June 2023. Solar power generation in India ranks fourth globally in 2021. Hydrogen has the best chance of being widely used in the future. Sources of hydrogen are plentiful, it has many uses, and most of the needed technology has already been developed. Stepping up to endless opportunities. India has huge ambitions in energy transition and plans to have 500 GW of non-fossil based electricity installed capacity by 2030, so that non-fossil cleaner fuel comprises of 50% of the installed capacity mix by 2030.

Answer
Wind energy is one of the most sustainable forms of energy currently available. It harnesses the power of naturally moving air to spin wind turbines, which in turn generate electricity. Not only is this great because it provides a regenerative form of energy, but it also does so without greenhouse gas emissions. Renewable energy sources which are available in abundance all around us, provided by the sun, wind, water, waste, and heat from the Earth are replenished by nature and emit little to no greenhouse gases or pollutants into the air. The social, environmental, and economical problems can be omitted by use of renewable energy sources, because these resources are considered as environment-friendly, having no or little emission of exhaust and poisonous gases like carbon dioxide, carbon monooxide, sulfur dioxide, etc. As with all new technological advancements, renewable energy is not as commonly used as fossil fuels simply because people don't know about it. People are much less likely to use green energy sources in their own homes if they don't even know they exist, or that they can choose to harness them. Coal, again, is the dirtiest fuel. It emits much more greenhouse gases than other sources – hundreds of times more than nuclear, solar, and wind. Oil and gas are also much worse than nuclear and renewable, but to a lesser extent than coal. Renewable energy can be solar, wind, hydro, geothermal, or biomass. On the other hand, fossil fuels can be natural gas, coal, and oil. Fossil fuels also emit CO2 when burned, contributing to greenhouse gasses and ultimately climate change. This is where lines can blur between energy sources. Renewable generate more energy than is used in their production, and produce fewer emissions than other power sources over their lifetime. While all sources of electricity result in some GHG emissions over their lifetime, renewable energy sources have substantially fewer emissions than fossil fuel-fired power plants. They differ from fossil fuels principally in their diversity, abundance and potential for use anywhere on the planet, but above all in that they produce neither greenhouse gases which cause climate change nor polluting emissions. Sunlight and wind, as such sources that are constantly being replenished. Renewable energy sources are plentiful and all around us. Fossil fuels - coal, oil and gas - on the other hand, are non-renewable resources that take hundreds of millions of years to form. First, there is a limited amount of fossil fuel resources in the world, and if we use them all we cannot get any more in our lifetimes. Second, renewable energy produces far less carbon dioxide (CO2) and other harmful greenhouse gases and pollutants. Using renewable energy in most regions and nations positively affects the environment by directly reducing carbon dioxide emissions. However, renewable energy in some remote regions may have adverse environmental impact. Although renewable energy sources produce relatively low levels of GHG emissions and conventional air pollution, manufacturing and transporting them will produce some emissions and pollutants. Harnessing power from the wind is one of the cleanest and most sustainable ways to generate electricity as it produces no toxic pollution or global warming emissions. Environmental and economic benefits of using renewable energy include: Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels.

Answer
Solar photovoltaics are the fastest growing electricity source. In 2020, around 139 GW of global capacity was added, bringing the total to about 760 GW and producing almost 3 percent of the world's electricity. Wind power is the second fastest growing source of energy worldwide. Several underwater turbines have been installed to tap the tidal flow of the geothermal energy stored in the earth's mantle. Cogeneration in Denmark produces a majority of its electricity. Wind energy Energy generated from the kinetic energy of moving air. Wind energy is the fastest growing major source of electricity in the world. One of the most important sources of energy is the sun. The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells. Solar energy and wind power are now among the most affordable renewable energy sources globally, and experts anticipate these costs to remain low for years to come. Solar and wind energy have continued to occupy the top spots in terms of the cheapest renewable energy sources. Both energy sources cost significantly less than fossil fuel alternatives and continue to become more affordable every year. When comparing the cost of energy associated with new power plants, wind and solar projects are now more economically competitive than gas, geothermal, coal, or nuclear facilities. However, wind projects may not be cost-competitive in some locations that are not windy enough. The common source of energy in villages can be animal dung and wood which can be used to produce biogas in a biogas plant. Biogas typically refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen.

Answer
Wind, solar, and hydroelectric systems generate electricity with no associated air pollution emissions. Geothermal and biomass systems emit some air pollutants, though total air emissions are generally much lower than those of coal- and natural gas-fired power plants. Renewable energy is energy produced from sources like the sun and wind that are naturally replenished and do not run out. Renewable energy can be used for electricity generation, space and water heating and cooling, and transportation. Derived from natural resources that are abundant and continuously replenished, renewable energy is key to a safer, cleaner, and sustainable world. Explore common sources of renewable energy here. It is generally believed that wind is the most efficient way to harness renewable energy. Because windmills can be placed in open areas also used for farming, they offer flexibility. Generally, rows of wind turbines are constructed along coastal areas where nothing can hinder the flow of wind. Environmental and economic benefits of using renewable energy include: Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. It is generally accepted that wind and solar energy are the ideal options when it comes to clean and sustainable sources of energy. They are the fastest-growing, the cheapest and do much less damage to nature and wildlife surrounding their sites as opposed to fossil fuels. Literally 'to make new again', a renewable resource is one that is naturally replenished with time, like the growth of new organisms or natural recycling of materials. Renewable energy is any energy production which uses one of these resources. India has set a target to reduce the carbon intensity of the nation's economy by less than 45% by the end of the decade, achieve 50 percent cumulative electric power installed by 2030 from renewable, and achieve net-zero carbon emissions by 2070. India aims for 500 GW of renewable energy installed capacity by 2030. Hydroelectric has the greatest impact on the aquatic environment, while geothermal plants and biomass have the least. Hydroelectric power plants are the most damaging to the environment compared to other renewable energy sources. Electricity from renewable resources such as solar, geothermal, and wind generally does not contribute to climate change or local air pollution since no fuels are combusted. Harnessing power from the wind is one of the cleanest and most sustainable ways to generate electricity as it produces no toxic pollution or global warming emissions. In general, hydroelectric power, wind power, and solar technology produce the least amount of pollution. When compared to burning fossil fuels like coal or oil, it is apparent that renewable energy sources create much less pollution because they do not emit leftover gases during energy production. Transitioning to renewable energy, and reducing reliance on fossil fuels, is one way to help slow down the effects of climate change. While renewable used to be a more expensive option, new clean energy technologies are lowering costs and helping to move economies away from fossil fuels. Generating renewable energy creates far lower emissions than burning fossil fuels. Transitioning from fossil fuels, which currently account for the lion's share of emissions, to renewable energy is key to addressing the climate crisis.

Answer
Yet, according to the International Energy Agency, as cited by Energy Intelligence, even when factoring in the cost of intermittency, solar remains cheaper than all other sources of energy, and specifically those generated using oil, gas, and coal.Solar and wind energy have continued to occupy the top spots in terms of the cheapest renewable energy sources. Both energy sources cost significantly less than fossil fuel alternatives and continue to become more affordable every year.Wind is now the cheapest source of renewable energy in India. While the death toll, direct and indirect, of renewable energy is much higher compared to that of nuclear, this is mostly due to one single catastrophic event. Overall, renewable energy should be considered safer because there is no risk of long-lasting radioactive contamination of the environment. Coal is the most important and abundant fossil fuel in India. It accounts for 55% of the country's energy need. The country's industrial heritage was built upon indigenous coal. Renewable Power to be 12% to 29% cheaper than Fossil Fuel in India, China, Australia: Report. India, China, and Australia are the top three countries where renewable energy is cheaper by 12% to 29% compared to the lowest-cost fossil fuel. These resources of energy can be naturally replenished and are safe for the environment. Examples of renewable sources of energy are: Solar energy, geothermal energy, wind energy, biomass, hydropower and tidal energy. India aims to achieve net zero emissions by 2070, and renewable energy is key to achieving this goal. Solar energy accounts for a significant share of India's renewable energy portfolio, and innovations in solar energy, such as rooftop solar systems and floating photovoltaics, are gaining ground. Solar power is one of the cleanest forms of energy because it does not emit any greenhouse gases. Out of all energy resources, we consider green power as the cleanest form of energy. So, if we were looking at clean energy on a spectrum, these would be farthest from “dirty” or emissions-heavy energy. Solar energy, much like wind, is one of the most sustainable energy sources currently available. In fact, given its modular and scalable nature where it can be utilized as part of massive solar fields or mounted on individual homes it may be the most practical form of sustainable energy in use today. Hydropower currently is the largest source of renewable energy in the electricity sector. It relies on generally stable rainfall patterns, and can be negatively impacted by climate-induced droughts or changes to ecosystems which impact rainfall patterns.

Which renewable energy has the lowest carbon footprint and which energy source has the lowest long term environmental impact?
Relevant answer
  • Aug 12, 2023
Answer
Wind energy has the lowest carbon footprint of all energy types. On a life-cycle basis, onshore wind emits 11 and offshore wind emits 12 grams of CO2 equivalent per kWh of electricity produced.Wind, nuclear, tidal, hydropower, geothermal, solar, and wave energy have the lowest carbon footprint. Per kWh produced, the energy sources emit between 11 and 48 gCO2 on a life-cycle basis. These energy types combat climate change and have various environmental benefits. There are four main types of low-carbon energy: wind, solar, hydro or nuclear power. The first three are renewable, which means these are good for the environment as natural resources are used to produce electricity. Reducing your carbon footprint means changing how you approach and participate in activities that produce greenhouse gasses. Fossil fuels coal, oil and gas on the other hand, are non-renewable resources that take hundreds of millions of years to form. Fossil fuels, when burned to produce energy, cause harmful greenhouse gas emissions, such as carbon dioxide.No, due to its relatively high lifecycle emissions, Coal is considered to be a high-carbon energy source. The median estimate of lifecycle emissions from Coal is 820 gCO2eq / kWh. It is generally accepted that wind and solar energy are the ideal options when it comes to clean and sustainable sources of energy. They are the fastest-growing, the cheapest and do much less damage to nature and wildlife surrounding their sites as opposed to fossil fuels. Per kWh produced, renewable energy emits between 11 and 740 gCO2 on a life-cycle basis. Depending on the type (solar, wind, hydropower, geothermal, tidal, wave, biomass), it can combat climate change and have various environmental benefits, but may still produce significant greenhouse gas emissions. Reduce energy consumption by installing only LED lights in your house and choosing energy-efficient appliances and heating and cooling solutions. Renewable and energy efficiency, boosted by substantial electrification, can provide over 90% of the necessary reductions in energy-related carbon emissions.

Answer
Sunlight is one of our planets most abundant and freely available energy resources. The amount of solar energy that reaches the earth's surface in one hour is more than the planet's total energy requirements for a whole year. As a source of energy, green energy often comes from renewable energy technologies such as solar energy, wind power, geothermal energy, biomass and hydroelectric power. Picking a clear winner is, however, tricky. Once you consider the emissions associated with their manufacture and installation, hydropower has the lowest carbon footprint, according to one major study. But there are also many other environmental impacts to bear in mind. Wind energy is one of the most sustainable forms of energy currently available. It harnesses the power of naturally moving air to spin wind turbines, which in turn generate electricity. Not only is this great because it provides a regenerative form of energy, but it also does so without greenhouse gas emissions. As a source of energy, green energy often comes from renewable energy technologies such as solar energy, wind power, geothermal energy, biomass and hydroelectric power. Often ranked as one of the most efficient energy sources, wind energy is harnessed all over the world. Of course, some spots are known as being windier than others, and companies typically make use of these spots by building wind farms filled with turbines there. Wind energy has also been used for hundreds of years. Renewable are often environmentally friendly but include power sources that can have some negative environmental impacts, such as hydropower. Clean energy refers to any energy that is net neutral or positive in terms of pollution and environmental impact.Renewable energy sources include wind power, solar power, bioenergy and hydroelectric, including tidal energy.
