Sustainable Energy - Science topic

Green hydrogen offers a multi-dimensional strategy for sustainable energy transition. Environmentally, it reduces greenhouse gas emissions and enhances climate resilience. Socially, it promotes job creation and industrial diversification. Fiscally, it enables revenue diversification, particularly in oil-dependent economies. It also aligns with the UN Sustainable Development Goals and the Paris Agreement, making it a strategic lever for long-term sustainability.

An Employee Value Proposition (EVP) is the unique set of benefits and offerings a company provides to its employees in exchange for their skills, capabilities, and experience. It defines the essence of what it’s like to work at a particular organization and plays a central role in attracting, engaging, and retaining talent.

Core Components of EVP:

Compensation & Benefits

Salary, bonuses, health insurance, retirement plans, paid time off, and other financial perks.

Example: Google’s generous parental leave policies.

Career Development

Learning opportunities, mentoring, training programs, internal mobility, and clear career paths.

Example: IBM’s investment in upskilling and reskilling its workforce.

Work Environment

Physical and digital workplace, safety, tools, flexibility (remote/hybrid), and office culture.

Example: Atlassian offering flexible work-from-anywhere policies.

Organizational Culture

Company values, leadership style, diversity & inclusion, and internal communication.

Example: Patagonia’s environmental mission reflected in its company ethos.

Meaningful Work

Purpose-driven work, opportunities to innovate, and a sense of contribution to a greater goal.

Example: Tesla employees motivated by the company’s mission to accelerate the world’s transition to sustainable energy.

Why EVP Matters:

Attraction: A well-communicated EVP helps companies stand out in a competitive talent market.

Retention: Employees are more likely to stay if their needs and values are aligned with what the company offers.

Engagement: When the EVP is lived and not just stated, it fosters greater employee satisfaction and productivity.

Employer Branding: EVP strengthens the company's image and reputation as a great place to work.

Best Practices to Craft a Strong EVP:

Employee-Centric Design

Gather input through surveys, exit interviews, and focus groups.

Authenticity

The EVP should reflect reality. Overpromising and underdelivering damages trust.

Tailored Messaging

Customize EVP messaging for different segments: Gen Z, Millennials, tech talent, etc.

Integration with Employer Brand

EVP should align with the company’s brand promise externally and internally.

Continual Evolution

Periodically update EVP to reflect changes in workforce expectations and market trends.

Examples of EVP Statements:

Salesforce: “Work hard. Have fun. Make history.” (focus on innovation and culture)

Unilever: “A better business. A better world. A better you.” (emphasizes purpose and personal growth)

Deloitte: “Where leaders thrive.” (focused on development and leadership)

In my opinion, the development of hydrogen power, despite its potential in energy transition, faces numerous systemic, infrastructural, technological and social constraints. One of the most important challenges is the cost of producing hydrogen, especially so-called green hydrogen, which is produced by electrolysis of water using renewable energy. The high cost of both the technology itself and renewable energy currently makes green hydrogen more expensive to produce than gray hydrogen, which is derived from fossil fuels and involves carbon dioxide emissions. The solution to this problem may lie in the development and scaling of electrolyzer technology and increasing the availability of low-cost renewable energy, which requires significant public and private investment and regulatory support.

I am currently conducting research on thermoelectric generators (TEGs) and their potential role in renewable energy generation. I am interested in understanding the various fields where TEGs can be effectively utilized. Specifically, I would like to explore applications in industries such as waste heat recovery, automotive, aerospace, and other areas that could benefit from sustainable energy solutions. If you have insights, resources, or examples of successful applications, I would greatly appreciate your input. Thank you for your help!

The development of renewable and carbon-free energy sources is a key element in the green transformation of the economy. On the other hand, the development of renewable and carbon-free energy sources is also an important issue in the context of diversifying energy sources and increasing the scale of the country's energy independence and enhancing energy security. Increasing the share of renewable and emission-free energy sources in the energy source mix is not only the realization of the key objectives of the green transformation of the economy and the achievement of the goals of sustainable economic development, but also a significant reduction in the cost of energy production and energy prices for end users in the coming years. How the structure of different energy sources should be designed is a product of many different determinants. In terms of the aforementioned various determinants of the impact and design of the structure of energy sources, including fossil fuel-based energy and renewable and zero-carbon energy, among others, stand out. : the level of possession by the country of certain energy resources, the energy policy adopted in the country taking into account to a greater or lesser extent the issue of the green transformation of the economy and the implementation of sustainable development goals, the terrain and other natural conditions conducive to the development of wind, hydro and solar power, the scale of geothermal water resources in the earth's crust, the financial feasibility of building large nuclear power plants, the technologies in use for the construction of residential and other buildings, and the most appropriate to the prevailing prosumer building formulas of small power plants that generate energy to power individual buildings, the technologies in place to enable the development of hydrogen power and other technologically innovative types of energy. Since the design of the most appropriate energy mix for a country requires the consideration of many different determinants in the process of research, planning, design and implementation of investment processes, so it is a good solution to involve in this process generative artificial intelligence technology, which has been trained in the process of deep learning on large data sets and Big Data information on various aspects of energy, including different types of energy, different energy technologies, different energy sources, etc., and the above-mentioned determinants of energy development.

In your opinion, what are the key factors that could enable photovoltaic (PV) technology to take the lead as the primary source of electricity generation?

I’d love to hear your thoughts on this topic. Do you think one approach outweighs the other, or are both equally important in shaping the future of PV technology? Let’s discuss and exchange ideas to explore the path forward for renewable energy!

According to the results of research conducted on this issue, it appears that the spread of hydrogen power as the basis of modern, emission-free energy requires both profound technological and systemic changes. One key aspect is the development of hydrogen production technology, particularly the green version of hydrogen, which is based on the use of renewable energy sources, such as solar or wind power, for the electrolysis of water. Currently, most of the world's hydrogen production comes from processes that emit significant amounts of carbon dioxide, such as steam reforming of natural gas. In order for hydrogen to be considered a truly carbon-free fuel, it is necessary to increase the efficiency and reduce the cost of electrolysis technology, as well as significantly increase the share of renewable energy in the energy mix.

I have described the key issues concerning the problems of the ongoing process of global warming, the negative effects of this process and, therefore, the need to scale up and accelerate the implementation of the green transformation of the economy in the following article:

Given the rise of enrichment technologies outside of states that are authorized to have such technologies, and the current work of LASER-based enrichment technologies that would reduce the size and complexity of such facilities (Snyder, 2017 [attached]), it becomes difficult to imagine a world where the flow of fissile materials can be properly controlled.

Despite this, the old limit of 20% of LEU still remains, even though certain civilian applications will undoubtedly require HEU (space propulsion/power). It must be noted that even at 20% U-235, it is possible to construct a viable nuclear weapon of limited yield, and countries seem find no difficulty in enriching even further, despite having limited budgets and being under heavy sanctions.

The energy density of reactor core designs could be far higher, giving them longer core lives and drastically lower waste volumes - a core at 50% enrichment could theoretically reduce the amount of fuel consumed compared to the same core at 5% enrichment by many times.

I think there may be some review of these limits in order soon to reflect the growing ease of enrichment and increased use of nuclear energy.

This question invites scientists and engineers to discuss groundbreaking materials and innovative approaches to energy storage—critical to advancing sustainable energy technologies. By focusing on "unconventional," it encourages out-of-the-box thinking and may inspire discussions on new solutions to ongoing energy challenges. It has the potential to engage a large community interested in renewable energy, materials science, and engineering.

Unfortunately, this is still the case in many countries, that the political lobbying by large fossil fuel burning energy companies to maintain the status quo continues to limit or block the possibility of rapid development of green, clean, prosumer energy, where energy is generated from renewable and emission-free energy sources on the basis of small power plants based on photovoltaic technology, windmills, etc. built by citizens or companies striving for energy independence. Prosumers of electricity, i.e. citizens and companies that, for example, install photovoltaic panels on their homes, property buildings, company office buildings, on the one hand, are a kind of small energy producers and consumers. Typically, large energy companies, through political lobbying, have established an obligation to connect prosumer mini-generators that produce energy from specific renewable and/or zero-emission energy sources to transmission grids operated by large, dominant energy companies, often with monopolistic practices. The obvious point is that excess energy produced by prosumers, once discharged into transmission grids managed by large power companies, can be used by other energy consumers. However, when large power companies are treated as second-class entities in the financial settlement of the energy produced by prosumers and discharged into publicly available transmission networks, when in the aforementioned settlement they do not receive the financial equivalent of the energy produced at the same rates that are applied to them when they buy energy from large power companies, it may be in the interest of prosumers who are treated unfairly in this way to become independent of these large, dominant power companies. In addition, the problem is exacerbated by the frequent situations in which large, dominant companies in the energy sector, energy corporations are very slow to implement, or do not implement at all, green energy transition processes and continue to generate energy from burning fossil fuels. Thus, in spite of the constantly cheap photovoltaic and other renewable energy technologies, in spite of the much cheaper production of energy from RES against conventional combustion energy, the processes of green energy transformation are still progressing too slowly, greenhouse gas emissions are still high and the process of global warming is still progressing rapidly. The solution to the above problem would be the introduction of legal regulations that would allow energy prosumers to function in a kind of closed circuit independently of the influence of large energy corporations with possible simultaneous connection to electricity transmission networks managed by the aforementioned large energy corporations that dominate the energy sector. The aforementioned connection to the transmission networks of prosumer RES installations would provide the possibility of draining the periodically generated surplus energy, so that there would be an opportunity to transfer this energy to other energy consumers who do not have their own RES installations and/or who, for specific reasons, have a periodic energy deficit. Besides, this type of solution could significantly generate a decrease in energy prices on the one hand and increase the level of national energy independence and energy security on the other. In a situation where a significant proportion of energy prosumers, i.e., citizens and companies operating in various energy sectors and industries, would have their own energy sources operating under different types of renewable and zero-emission energy sources, a large diversity in the mix of different energy sources would also, on the one hand, be an important factor in energy security. On the other hand, thanks to this solution, the process of green transformation could, in real terms, significantly accelerate.

For example, in Poland in recent years, green energy based on photovoltaics is mainly developed by citizens, prosumers, individual customers, who are at the mercy of large, dominant energy companies managing transmission networks. The travesty of this solution is that these large energy companies have lobbied for the introduction of regulations according to which prosumer photovoltaic installations and other mini RES power plants must be connected to the aforementioned power transmission grids, while these grids are mostly built many years ago on the basis of already outdated technologies and are unable to accept surplus energy from prosumers when the sun suddenly sets and the wind blows a little stronger than usual. Recently, there have also been situations in which the authorities set up for this purpose have slowed down the processes of issuing approvals for new connections to the transmission grid of successively created by prosumers photovoltaic and/or other mini RES power plants. The paradox of the situation that has arisen is also that many entrepreneurs in various industries and sectors of the economy are interested in becoming energy prosumers in order to build photovoltaic and/or wind energy-based power plants near their company or enterprise, but the problems mentioned above are the reason why still few entrepreneurs choose to do so. Another paradox is that financial subsidies are available, including grants from the National Recovery Plan for the development of prosumer RES power plants, but the aforementioned problems are a key factor inhibiting the possibility of accelerating the realization of the green energy transition, in which prosumer RES-based power plants could account for a large share. From surveys conducted among entrepreneurs running their companies and/or businesses in various sectors and industries of the economy, that they would be willing to become prosumers of energy generated from their own RES power plants, and would thus be eager to change their business by greening it, by increasing the scale of application of sustainable development goals, by adding the idea of green business to the company's mission, as it is known that the pro-climate, pro-environmental, pro-environmental awareness of citizens, i.e. customers of their product and/or service offerings, is constantly growing.

The nexus between energy and the environment is a critical concern in today's world, as the need for sustainable energy sources becomes increasingly evident due to the challenges posed by climate change and resource depletion. Keeping up with the latest developments and research in this field is essential for informed decision-making and policy formulation.

The essence of sustainability derives from the study of sustainable, human-interference-free, biodiverse natural ecosystems of specific natural environments, which contain a wealth of species of flora, fauna and micro-organisms linked by many different ecological relationships. The ideas of sustainability are applied in developing the characteristics of sustainability in various aspects of human activity, the development of civilisation, various aspects of the economy, etc. The importance of the role of sustainability and its application in the context of economic development is growing in direct proportion to the scale of the increase in the negative effects of the development of human civilisation, which include the increasing scale of environmental pollution, the increasing scale of deforestation, the increasing scale of betonosis i.e. These include the increasing scale of environmental pollution, growing scale of deforestation, increasing scale of betonosis, i.e. urbanised areas and shrinking green areas in cities, growing emissions of greenhouse gases, accelerating greenhouse effect, accelerating global warming, growing scale of soil depletion, forest fires, weather anomalies and climatic and natural disasters, decline of biodiversity of the planet's natural ecosystems, etc. The aim is to reverse these negative processes, which have a negative impact on the environment. In order to reverse these negative processes and save as much of the planet's threatened biosphere as possible, it is necessary to carry out a green transformation of the economy on a multifaceted scale. In this respect, a system of 17 Sustainable Development Goals (SDGs) has been defined within the framework of cyclical UN conferences on this issue and the global problems of climate change, which should be implemented on as large a scale as possible in order to reduce the scale of action and negative effects of unsustainable, intensive, rapid economic development within the framework of a predatory brown economy based on high scale exploitation of natural resources, including non-renewable natural resources, energy production mainly based on dirty fossil fuel combustion energy, increasing scale of environmental pollution, increasing scale of greenhouse gas emissions, negligible scale of secondary raw material use and recycling, accelerating global warming, rapid degradation of the biosphere, decline of biodiversity, etc. One of the key aspects of achieving a green transformation of the economy is to build a zero-carbon economy based on sustainable, zero-carbon, green energy, i.e. the development of renewable and zero-carbon energy sources. This is essential and should be realised in 100% by the end of this decade of the 2030s at the latest if the main strategic goal of international environmental and climate policy is to be met, i.e. to halt the global average global atmospheric temp. increase of max. 1.5 degrees C since the beginning of the first industrial revolution. This goal was defined and established for implementation at the UN conference on this issue, i.e. during the so-called Paris Agreement of 2015. Of course, the green transformation of the economy is a much more multifaceted process, in which all sectors and branches of the economy, many fields of human activity, many aspects of the development of civilisation, the ongoing development of energy, industry, agriculture, technological progress, etc. should be involved in practice. The green transformation of the economy should take place within the framework of a pro-environmental and pro-climate transformation of the classic growth, brown, linear economy of excess to a sustainable, green, zero-emission growth and closed loop economy, in which the implementation of the goals of sustainable development and increasing the scale of sustainability at the level of development of civilisation in relation to the surrounding environment should be strategically important objectives.

The transition to a sustainable energy infrastructure is a critical component of mitigating the effects of climate change and ensuring a healthy environment for future generations. Fossil fuels, while providing a convenient and cost-effective energy source, are finite resources and their combustion leads to air pollution and other environmental issues. Therefore, it is essential to find alternative energy sources that are renewable, accessible, and affordable for all people. This question is important as it seeks to identify how we can create an energy infrastructure that is sustainable and equitable for all people.

If the currently developing energy crisis worsens significantly, how will you reduce your heating energy consumption and/or increase your household energy security in a situation where heating prices would increase by several tens of percent in the next heating season?

Nowadays, energy-saving solutions and systems are being developed due to rapidly rising fossil fuel prices. For example, solutions are being proposed for lowering the heating temperature in living spaces by a few percent when heating prices would still rise significantly. At present, many citizens are considering new investments in their household to increase energy security. Questions arise: maybe it is worthwhile in the near future, before the next heating season, to install new, renewable sources of heat and/or electricity at home, to insulate the house façade, etc.? Or are there already affordable new eco-innovations and green energy technologies that could be used now to increase energy savings? Besides, an energy crisis is currently developing and, in the long term, so will a climate crisis. When building a house now, it is important to take into account both the potential deepening of the energy crisis and the climate crisis in the future. In addition, the future correlation between the effects of both crises must be taken into account when planning heating systems and the electricity supply. Among the currently fast-growing green building heating technologies are the installation of heat pumps powered by electricity from photovoltaic panels installed on the roof of the house. In the future, the electricity supply for heat pumps may also come from domestic small-scale hydrogen power plants or nuclear fusion mini-reactors.

The SDG7 seeks to ensure access to clean, affordable and sustainable energy for all. The fuelwood crisis in the 70s/80s was triggered by the Arab-Israeli War (the 1973/4 oil crisis) when astronomical increases in prices of petroleum products especially LPG led to a dramatic increase in the demand for cheaper cooking fuels such as firewood and charcoal. The COVID 19 pandemic coupled with the Russia Ukraine war has sparked another global energy crisis similar to what happened in the 70s. Is another fuelwood crisis looming? If yes what can be done to prevent it?

I have secondary data on sustainable energy for 35 Sub-Saharan African countries with 4 IVs and 34 sub-variables in all. I should have collected data for all the countries in the region but for incomplete data for others. I can't figure out whether the data set is enough. I ran the analysis for the available data but none of the variables contributed significantly to the DV.

I am developing a model to optimise a sustainable energy system for community buildings. The system uses renewable energy, battery storeage and intelligent building management to optimise the energy used by the building. I cannot find any data on electricity use patterns for community builings (Village/Church Halls) across the year. There seems to be lost for domisetic property and some for normal commercial property (offices/shops/factories). I have limited data which shows a marked summer/winter pattern but would be grateful if anyone could share any larger data sets. At the moment the buildings are all in the north of England but ideally we woudl like to develop a model that works anywhere.

CO₂ is used as raw material for chemical syntheses. It paves the opportunity to mitigate the greenhouse gas (GHG) emissions. However, it is not mathematically or logically proved yet that carbon capture benefits the environment in terms of resource efficiency. In my opinion, I believe that the life cycle assesment (LCA) would be the most suitable tool to quantify the resource-based benefits due to carbon based methane (CH₄) production and to prove the resource efficacy of carbon capture.

I would like the researchers who read this discussion to provide their own ideas on whether LCA is the most suitable tool to identify the carbon capture resource efficacy or are there any methods better than LCA that can be applied on CO₂ based methane production.

I am about to conduct a research for Master of Science in Sustainable Energy Engineering, so I want to be assisted on the better tool between HOMER and MATLAB for technical and economical analysis. Thank you!

Looking for your kind suggestion.

Do you see that we use energy resources efficiently?

Conventional energy resources are very limited. So, we must use them with highest savings and great care. Unfortunately, this is not the case; whenever you direct your sight, you see that people are wasting these precious resources and misusing them.

On the other side, scientists and engineers could not until now produce efficient conversion methods for these resources. Think about the conversion efficiency of thermodynamic machines.

The present civilization, which is based on machines driven by energy, may be in danger if we do not make up our minds for the issue of energy.

What is your opinion on this matter?

With coal mines still being planned and opened with 30-40 year lives, is coal seam gas (CSG) a real clean option or is it just as dirty as coal for our global power stations? Most CSG wells have lives of up to 15-25 years. When are we going to take other energy sources, such as solar and wind seriously? Can they be taken seriously as the petroleum industry buys shares into renewable energy sources and places them on the back burner until expensive lead in costs for coal and gas mines and wells can be recouped?

Can anyone guide me about the review time of "Renewable & Sustainable Energy Reviews"? What is meant by "With editor status"? Its been four months, I have been observing the same status on the website

Power-to-heat (P2H) shows how we can use renewables for heating. Power-to-heat technologies have been on the market for quite some time now, with heat pumps being the most important. However, they are only efficient at lower temperatures. Whenever very high temperatures are needed – for example, in the industry – electrode boilers are used.

So what do you think? Which technologies do you think will substitute the current fossil-fuel-based heaters in the future European energy system?

In Bangladesh, the proved reserved of natural gas 34 TCF which will lead the country next 20 years and currently 82% natural gas consumed in the power sector for power production. Whereas only 3% of electricity produced from renewable energy sources. However, there is an immense interest in using renewable energy like solar, biofuel, geothermal, wind due to environmental and economic concerns [Uddin et al. 2019].

Do you think Bangladesh can do it in the long-term, for example in the year 2100? If "yes", how? If "No", why?

I would like to know which large sustainable energy demonstration projects are running right now, in a country or series of countries, which are too premature to already being subject of a scientific publication yet. Can you tell me if you know such projects or series of projects??

Since, the world has heavily relied on oil and gas sources for their energy, is it possible to completely transition to renewable sources, taking in sense that we have our vehicles and machines still based on internal combustion engine?

China is the world's biggest producer of solar power. It produces two-thirds of the world's solar panels. It installs enough to cover a football pitch every hour of every day and is installing one wind turbine every hour. It doubled its solar capacity last year. It has already exceeded the government's own target for solar capacity for 2020 and currently generating about 20% of the country's energy.

India has come a long way in renewable energy in the past decade. The Government of India aims to reach renewable energy capacity of 175 GW by 2022 in which 100 GW is planned through solar energy. Despite 12 times of capacity growth to 31 GW in solar energy, it still contributes only 3% of total electricity. It would be possible that India may not achieve its target by 2022.

What are the problems India is currently facing to achieve this 100 GW goal by 2022?

A lot of today's world vices can be eliminated if certain targeted modules and adapted curricula are introduced in the schooling system. One of these vices is energy squandering with all its negative consequences for the planet (e.g. depletion of finite energy sources and the subsequent climate change).The routine energy-related behavior and proves that this behavior changes to a more energy efficient one, after the dissemination of relevant information and the participation into the energy education projects. Namely, response percentages indicating the energy-efficient behavior increased after project participation while the ones indicating an energy-squandering behavior decreased.

Need for renewable energy education and training at all levels is globally recognized. During the last three decades a large number of countries across the globe have initiated academic programmes on renewable energy technologies and related aspects. A review of published literature on renewable energy education initiatives across the globe, challenges faced, and potential approaches towards efficient and effective solutions is needed.

In Your Opinion

I am Mechanical Engineer and doing MSc. Project Management (1 Year Program). Looking for Master thesis topic which connected to energy sector (preferable sustainable energy) and construction (Energy efficient building ), but confuse to construct topic. Need topic suggestion related to this sector, as i have to make career further in this sector.

Thank You in Advance

How should new economies be developed according to the green economy concept with which instruments and pro-ecological policy reforms should be developed to make it possible to achieve globally sustainable environmentally-friendly economic development in the next years?

How effective green economy philosophy should be developed in a pro-ecological socio-economic policy in order to solve key development problems of human civilization, ie environmental pollution, effective and quick in the reduction of greenhouse gas emissions and thus slow down the ongoing process global warming, activation of the development of electromobility, renewable energy sources, development of organic agricultural production, development of production of biodegradable packaging, etc.

In view of the above, I am asking you: How should green economy be developed to allow for a globally sustainable pro-ecological economic development?

Please reply

Energy demand and environmental issues.

We live in a touristic area with sustainable energy production, e.g. biogas. Terrible smells are rather annoying. So my question: Are there solutions by molecular biology or bionics?

Dear colleagues, does any of you have access to information - what kind of carbon footprint have panels based on perovskite photovoltaic cells? Is it the same as with "ordinary" monocrystalline or polycrystalline panels? How is the built-in energy for the cells?

I've found only these:

monocrystal PV modules - c.a. 4750MJ/m2 and 242kgCO2/m2

policrystal PV modules - c.a. 4070MJ/m2 and 208kgCO2/m2

Failure of a cracked solid is frequently encountered in nature. I am searching for examples of thermoelasticity or elastostatics problems that are encountered in renewable and sustainable energy researches.

I'm currently working on a design of a hydroelectric system that can be free of environmental and economic concerns and reliable to operate in Ocean and Sea.

It is a huge project In planning. If you are an expert or have experience in this area, I would greatly appreciate your support to make this project happen.

At the dawn, of the 21st century during a reign governed by money and greed the buzz in the economic and technological race was to build an economy based on hydrogen. A couple years later with the financial internet crisis of 2001 all this buzz disappeared and we entered a reign of terror and war governed by a different type of ethics…

Now, we are facing a different challenge: the climate change due to the over consumerism and accumulation of pollution since the 19th century. After decades of foolish hard geo-engineering experiments scientists, engineers and technologists have to come up with all kind of ineffective “solutions” (some are doing worse than good) to master the astronomical forces involved in order to control the effects of climate change and continue business as usual…

Hydrogen is seen as a non-polluting way to store renewable energies and nuclear energy since its recombination with oxygen produce only pure water. It is a transportable fuel for vehicles and other tools and devices running on electricity.

Further, some scientists fascinated by the solar nuclear energy (“illimited source of free energy”) have convinced uneducated deciders that the ultimate goal was to master the nuclear fusion and build an experimental international power plant called ITER.

Please, justify your position by sound arguments.

Thank you in advance for your esteemed expert contributions and for your understanding.

Kind regards.

No personal attacks, insults, pollution of the answers with popular press clippings from other discussion will be accepted.

Planning a system like a farm, how to calculate which sustainable energy could have the smallest CO2 impact? Thank you.

Fellow Researcher can you please suggest a relevant PhD research topic in Renewable/Sustainable energy Systems? I'll appreciate if you can help me identify a clear problem and an incline to the possible solutions.

The utilization of any end product as fertilizer also remain on the earth that contribute for pollution and global warming through the release of greenhouse gases. Then how it is zero waste?

Obviously, smart grid technology is growing fast. Its contribution to energy efficiency and sustainability is undeniable. I would like to see deep in to it, what it is like, what advantages and disadvantages it might have. Dear RG members and researchers, you are welcome to to provide any reasonable comment on the topic under question.

I am in search for articles that address metal scarcity and how it could potentially affect the energy transition. I have found good studies on copper but not many on other metals. Suggestions?

Thank you.

The population of Africa is growing at a rapid pace with some estimates projecting 2.4 billion by 2050. Even the more conservative estimates indicate a massive growth by the end of the century.

Clearly the people of Africa will need a much larger infrastructure in terms of cities, roads and energy capacity. Can renewable energy sources really cope with theis rapidly changing demographic or must Africa consume more fossil fuels and nuclear generated energy?

Some of the scientists and environmentalists already made a statement that fossil fuel will be depleted in the future. So what will happen to the internal combustion engine (ICE) once it happened? can we used another source of fuel or it will be discarded?

Dear all,

I am wishing to investigate on linkages between microfinance and sustainable (renewable) energy and/or climate change issue. I have found the area has limited previous studies. Thus, I am looking for suggestions, opinions, advices and sources of material, literature and data.

It would be helpful, if you put your thought about different dimensions of the linkage between mentioned issues.

Particularly, how microfinance can support to sustainable energy and/or climate change adaptation?

You can suggest me from both institution’s and borrower’s perspectives.

Thanks in advance.

Our planet is facing enormous challenges of pollution, Global Warming and Climate Change, Healthy Food Production, lack of Sustainable Energy. For survival of mankind for many generations to come, it is critical to create next generation of Smart Science and Engineering Education & Training for future scientists and engineers. With proper education and training they will be able to solve the world's most important issue related to environment, health, energy, weather change and global worming.

Next-generation biofuels are toxic to microorganisms producing them, thus adversely affecting the production yield. The expression of efflux pumps presents a promising strategy for many biofuels like the longer chain alcohols, alkanes, alkenes and cyclic hydrocarbons, however recent studies show evidence that these are not effective at exporting short-chain alcohols. Could there be methods to make these efflux pumps less specific to solvents and still perform their function?

Eco-exergy is a combination of exergy analysis and power plant environmental impact analysis.

How is the mechanism analysis

How can we get the input datas for biomass,biogas for building the hybrid energy systems using HOMER?We can get the solar radiation data,wind velocities,etc for the IRES using HOMER based on the metereological data...But,how can we get the same for MHP,Biomass and Biogas plants?

Can anyone recommend me any article or book, which can help me with regulation and shifting of domestic appliances for matching energy consumption to generation in micro-generation systems ( smart buildisng with solar PV panels for example )

I am interested in the optimisation of energy security-related indicators in order to make sustainable energy planning at country level. Thanks in advance.

I am interested a new technology for geothermal electricity production .from low temperature geothermal sources.
