Investing in renewable energies in Africa

renewable energies in Africa

Wind and Solar Growth: In 2023, wind and solar provided 27% of the EU's electricity, pushing renewables to 44% of total generation. Wind surpassed gas, with solar growth fueled by cost declines and policy support. Fossil Fuel Decline: Fossil fuels fell to under a third of the electricity mix, with coal and gas dropping 26% and 15%, respectively. Decarbonization: Power sector emissions fell by 19%, driven by renewable adoption and a 6.4% drop in electricity demand since 2021. Infrastructure Focus: Increased renewables emphasize the need for energy storage and enhanced grids. Policy Impact: EU targets and subsidies drive growth, but faster deployment and infrastructure investment are critical.

Novel Evaposomsis Cycles for Ambient Thermal Energy Harvesting

Cycle 1:

The two different solutions can be separated by semipermeable membrane at the lower part, meanwhile, they can have different vapor pressure at their gas/liquid interface, as described by Raoult's law.

A novel cycle is generated by vapor pressure gradient and subsequent reverse osmosis process.

The cycle is beginning with more evaporation at the site of low solute concentration, then after, more condensation at the site of higher solute concentration, which increase hydrostatic pressure and this induce reverse osmosis to complete the cycle.

Cycle 2:

We can boost pressure gradient and energy harvesting capacity by adding a soluble gas with high vapor pressure like NH3, CO2 , HCl, etc. to the above cycle.

All processes are the same as cycle 1 except for reverse osmosis which replaced by diffusion according to chemical potential of the dissolved gas or products like ( NH4OH or HCO3).

As illustrated at the diagram below.

Notes:

1. The size of the device can be reduced by adding a pump to decrease hydrostatic pressure dependency meanwhile ensure the exchange of dissolved gas and products.

2. Both evaporation and condensation can also be potentiated by liquid sprinkler or surface expansion by sponge 🧽 for example.

..... .... ....

AI paraphrase and description:

The diagram illustrates the setup of the Evaposomsis Cycles process between two chambers: a Low-Solute Chamber and a High-Solute Chamber. Here’s an analysis of each component and how the cycle operates based on this illustration:

Components of the System

1. Low-Solute Chamber:

Contains a solution with a low concentration of solutes.

Has CO₂ bubbles, indicating the presence of a soluble gas to enhance vapor pressure.

Evaporation occurs in this chamber, where water vapor (and CO₂ gas) is generated.

2. High-Solute Chamber:

Contains a solution with a higher solute concentration, which lowers its vapor pressure.

Condensation occurs here as the vapor from the Low-Solute Chamber migrates across the valve and condenses due to the lower vapor pressure in the High-Solute Chamber.

The condensation process here increases hydrostatic pressure.

3. Semipermeable Membrane:

Positioned between the Low-Solute and High-Solute chambers.

Allows selective transport of solvent (water) molecules while blocking solute particles.

Facilitates reverse osmosis as the increased hydrostatic pressure in the High-Solute Chamber drives the solvent back into the Low-Solute Chamber.

4. Valve:

Positioned at the top between the chambers.

Likely acts to regulate vapor flow from the Low-Solute Chamber to the High-Solute Chamber, allowing the evaporation-condensation process to proceed under controlled conditions.

Cycle Operation

1. Evaporation and Vapor Flow:

Due to the lower concentration of solute in the Low-Solute Chamber, there is a higher vapor pressure.

The solvent evaporates, and CO₂ may also enter the vapor phase, increasing the total pressure and creating a strong pressure gradient toward the High-Solute Chamber.

2. Condensation in the High-Solute Chamber:

The vapor flows through the valve into the High-Solute Chamber, where it encounters a lower vapor pressure.

Condensation occurs in the High-Solute Chamber, causing an increase in the liquid level and hydrostatic pressure.

3. Reverse Osmosis Effect:

As condensation raises the hydrostatic pressure in the High-Solute Chamber, it forces the solvent through the semipermeable membrane back into the Low-Solute Chamber.

This action re-establishes the initial solute concentration gradient and restarts the cycle by restoring conditions for further evaporation in the Low-Solute Chamber.

Enhanced Vapor Pressure Gradient (Cycle II)

The addition of CO₂ gas in the Low-Solute Chamber increases the vapor pressure further, strengthening the vapor flow and boosting the overall energy output of the system.

Summary

This cycle sustains energy production by exploiting differences in vapor pressure, solute concentration, and hydrostatic pressure, creating a self-sustaining loop for continuous, low-grade energy harvesting. The addition of CO₂ intensifies the effect by amplifying the pressure gradient across the chambers, allowing for more robust energy output.

For the first time ever at the end of July 2024, more energy was generated in the European Union from renewable energy sources than from fossil fuels. This fact may suggest that due to rapidly developing renewable energy sources, the European Union may achieve zero-carbon of its economy much sooner than 2050. However, the structure of energy sources, including renewable, zero-carbon and emission-based, fossil-fuel-burning energy sources, varies widely across the European Union. Also, the pace of development of individual renewable and emission-free energy sources, the scale of financial investment and the large-scale use and implementation of new green energy technologies and eco-innovation varies considerably across the European Union. On the one hand, in Norway, for example, almost all of the energy generated comes from renewable energy sources. On the other hand, in Poland, since the beginning of the systemic and economic transformation, since 1989, for more than 3 decades financial subsidies were provided from the state's public finance system mainly to the fossil fuel extraction sector and the energy sector based on the combustion of these fuels. As a result, today in Poland, almost 3/4 of the electricity and even more of the thermal energy is still generated from dirty combustion energy based mainly on burning hard coal and lignite. In addition, hard coal mining in Poland within the framework of deep, highly methane mines, especially deep seams for many years is no longer profitable and generates additional costs for the state's public finances. It should be added that 90 percent of coal burned in the European Union to heat homes, apartments, etc. is the share of Poland alone against the background of the aforementioned European Union. And, for example, in Germany, which has a much more developed renewable and emission-free energy sector, for many years housing cooperatives have been generating thermal energy to heat apartments, entire housing estates from renewable energy sources, such as using heat pumps powered by electricity generated from photovoltaic panels. So Poland has a lot of work to do in terms of green energy transition. Unfortunately, the plan to build the first nuclear power plant is once again being postponed by the next government in Poland to an undefined and distant future.

I described the key aspects of a closed-loop economy, including a green, sustainable economy, in my article:

In the following article, I included the results of the research I conducted on the connection of the issue of sustainable development, the genesis and meaning of the Sustainable Development Goals, the essence of sustainable development in the context of social, normative, economic, environmental, climate, as well as human rights aspects, etc. The research also addressed the issue of key determinants of human existential security as an element of the concept of sustainable development.

I invite you to familiarize yourself with the issues described in the publications given above and to scientific cooperation in these issues.

In view of the above, I address the following question to the esteemed community of scientists and researchers:

And what is your opinion on this topic?

What do you think about this topic?

#RenewableEnergy #Research #Teaching #Sustainability #InternationalOpportunities

The integration of renewable energy systems (e.g., solar panels, wind turbines) with traditional building energy management systems (BEMS) presents both opportunities and challenges for achieving optimal energy consumption. While renewable energy offers a sustainable solution to reduce reliance on fossil fuels, several technical, operational, and economic barriers can arise when combining these systems with conventional building energy infrastructure.

What are the most critical challenges in this integration? Are there issues related to system compatibility, storage and distribution of renewable energy, intermittency, cost, or user behavior? Additionally, how can advanced technologies like smart grids, energy storage systems, and predictive algorithms help in overcoming these challenges?

Can anyone recommend free to publish journals for publishing papers on renewable energy.

Dear S. Serna, T. Gerres, R. Cossent

I read your article:

Multi‑Criteria Decision‑Making for Renewable Hydrogen Production Site Selection: A Systematic Literature Review

My comments:

1- In the abstract you say “The review shows that different methodologies and criteria are used depending on the spatial scale of feasible alternatives. Many criteria are related to renewable energy production, such as wind speed or solar irradiance. However, most articles also consider parameters such as hydrogen demand or access to water”

The underlined is strange, all methods should be able to solve a certain problem; there is no reason on the contrary. The scenario is always the same: A set of alternatives subject to a set of criteria. The problem lies on the fact that most methods are unable to MODEL, let alone SOLVE complex scenarios, and in my opinion, this is the biggest problem in most MCDM methods. They are too elemental, since they are not able to represent reality even approximately.

Regarding feasible alternatives, it is meant to indicate that they are possible. That is, if the DM is thinking in say PV, it is feasible but not always, because it may not be enough. In some high latitudes like north Europe or Asia, this method is possible, of course, but it may be not feasible due to cells poor performance, because reduced hours of irradiation, weak irradiation, excessive snow that can cover the cells, etc. Same for tropical areas where the temperature is too high, since it reduces the PV cells power, or because sand covering them, or due to the absence of a nearby electric grid.

Since there is normally a mix of locations that fulfill the minimum requirements, if the main objective is producing energy from de Sun, you can select locations with a large irradiance and/or strong winds, and study the joint location of the two alternatives in some places, but not in others.

If you are aiming at producing hydrogen, you need water, however, you can also consider if some places are also good at the same time for irradiation and wind, because you need electricity for getting hydrogen from the sea water by electrolysis. If some MCDM cannot manage this blend, they cannot be used in a scenario like this. Precisely, MCDM is looking at taken advantage of all opportunities to select something. Therefore, the selection of the MCDM method to use overrules all other considerations.

2- “There is no consensus on how to weigh criteria affecting renewable electricity generation versus those affecting hydrogen production”

I do not see why.

3-Page 2 ”Finally, the results are usually validated by applying another MCDM method and comparing the ranked alternatives. However, this validation is not always done”

Validation is a misconception since no MCDM results can be validated, simply because there is not a yardstick to compare to.

4- “The fourth stage assigns weights to the criteria. In the fifth stage, alternatives are compared based on the weighted criteria. Finally, the results are analysed and validated.”

Regarding assigning weights, not all MCDM methods used weights; they compute the criteria relative importance by other means.

Weights measure criteria significance, which does not mean that they can be used to evaluate alternatives. As a matter of fact, they don’t (Shannon’s entropy do that, not weights).

No validation is possible. Validation is a wrong assertion by many authors. The process of comparing rankings involving different methods is useless. The only possibility of validation is to compare with reality, but since we do not know it, all this exercise is superfluous. And if we know reality, what do we need MCDM for? See the incongruence?

5- In page 2, how do you know if an alternative is feasible? You don’t know it, because feasibility means simultaneous compliance with all criteria, something unknown until a problem is solved mathematically

6- In page 3 “At the same time, classification criteria can be either benefit or cost criteria”

Not all criteria aim at reducing a cost or at increasing a benefit, there are criteria that refer to environment, regarding established pollution limits, as NOx, or to created consumption values, as in the case of water, or to production limits due to machine capacity, which are not connected to cost or benefit.

7- “Some articles also introduce new categories, such as natural resources ([9, 13, 14]) or geographical criteria”

And this is absolutely correct and must be mandatorily considered. There should be no limits for the number of criteria; they can be any, either 8, 50 or 120. The problem is if a MCDM method can manage them, and of course using resources and targets. Otherwise, the problem is flawed because all criteria need resources, and these are finite. The no using of resources in 98% of methods hints that they are unlimited, and then yielding dubious results because, they may be consuming resources that are well below of those needed. Here is an example of weakness of most MCDM methods. Thus, the DM may reach a solution, but he does nor know if it is or not feasible.

8- In table 1 you make all criteria quantitative. What about qualitative, like people opinion, people acceptance and others? If a method does not accept a mix of quantitative and qualitative criteria, if it does not take into account resources and targets, if it does not allow a mix on criteria calling for maximization, minimization or equalization, they cannot be used in serious problems.

9- It is interesting that you considered 45 criteria, a very reasonable number not often seen, to involve all class or criteria that can influence the site selection, and your concept of exclusivity is not often considered either. These criteria involve technical, economic, engineering, social criteria, as it must be.

However, I do not understand why different authors treat them separately, when the 45 can perfectly be integrated in a sole matrix. If there are say, 3 potential locations, we could build a matrix with these 3 locations in columns and 45 criteria in rows or vice versa. However, it would be more productive if we consider simultaneously in a unique matrix the 3 locations, the 45 criteria, and the 2 different sources, that is: Photovoltaic and wind, to generate only a product, hydrogen.

It can be done, if each location is subdivided in 2 columns, corresponding to the electricity sources, and placing in the intersecting columns cells, a value corresponding to each one. As an example, assume for instance 2 criteria out of 45, and the 2 sources.

In the intersection of each sub column and a criterion we have these options:

Let’s analyze PV

In general, closeness to sea and wind force are irrelevant, therefore, these boxes are left blank.

The only significant columns for PV are those corresponding to irradiation. Assume that we have measured irradiation in the three locations (A, B and C), as follows:

For A: 1250 kWr/m2-year, we put that value for site A. Perhaps for site B there is on 850 kWh/m2-year, and we put that value in the corresponding intersection. And site C, in other latitude, has a low 450 kWh/m2-year. Thus, we have the values for the three sites, and we establish say that it must be maximized. The irradiation criterion will look as:

For site A: 1250 0

For site B: 850 0

For site C: 450 0

Therefore, for PV we have: 1250, 850, 450

Obviously, the criterion wind force is very significant here. Assume that we have measured these values:

For site A: 0 2.5 0 m/s

For site B: 0 8.5 0 m/s

For site C: 0 5.1 0 m/s

Therefore, strong wind criterion will be: 2.5 8.5 5.1. We must indicate the software that the result must be greater than 5 m/s, which is the estimated minimum wind speed

In this way it is possible to determine the best location as well as the best source of energyfor each one, to produce hydrogen

Is it possible to consider that for a same location there could be two or more inclusive sources. For instance, in a desertic area we can have that in some location, both PV and wind can be installed, if a site possesses the two conditions, like high irradiation and enough wind speed, provided that there is enough space for both.

10- Page 7 “This method is based on assessing the variability of each criterion among the different alternatives by assigning higher weights to those with greater variation”

There is a mistake here, because weights are not related to variation, it is related to the dispersion of the criterion performance values, not to the relationship between criteria.

Performance values variation is defined by entropy. High entropy values mean small variation, with maximum entropy equal 1, with no dispersion or variation. The minimum entropy is 0, which corresponds to lowest entropy value, and with the largest dispersion or variation, and the largest amount of information,which is what really matters, because information is what evaluates alternatives.

11- “The subjective weights of water availability and annual hydrogen production are 0.06 and 0.03, while their objective weights are 0.16 and 0.005. In the frst case, the objective weight is lower than the subjective weight assigned by a group of experts”

To make 1 kg of hydrogen normally you need 9 litres or 9 Kg of water. Therefore, the relation is 0.11

According to your numbers the relation between both is 0.50. It appears that subjective values are wrong as well as the objective weights where you need 150 grams of water to get 5 milligrams of H2 or 30 tons of water per kgr of H2. I suggest to check your figures.

12- “This method focuses on interactive decision-making, where the criteria and preferences of the decision-makers can change during the process”

Your definition of iteration is correct but you do not need a DM for that. The Simplex algorithm, which is an Excel add-in in your computer, under the ’Solver’ name, does it automatically and very very fast and without errors, using Linear Programming

I hope that my comments may help

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.

Hello everyone, Are there any references about relationship between renewable energy and its impact on oil demand?

The structure of the energy mix of various energy sources is determined by a number of factors. On the one hand, these are historical factors, technological, geographic, natural, economic conditions, etc. On the other hand, these are the determinants arising from a certain adopted energy policy, including taking into account the implementation of the goals of sustainable development, the principles of green transformation of the energy sector, social climate and environmental responsibility, and taking care of prospective future energy security. Taking into account the aforementioned determinants, there is a non-uniform structure of the energy mix of various energy sources in different countries. Taking into account the mentioned energy policy issues, the structure of the energy mix of various energy sources should be constructed in such a way that the national energy system, on the one hand, is characterized by independence from various factors and a high level of energy security, and, on the other hand, should also be in line with the green transformation of the economy and the implementation of sustainable development goals. In Poland in recent years, in terms of renewable energy sources, photovoltaic was the most significant in the structure of the share of installed capacity. Wind power came second, hydroelectric power was third, followed by biomass and biogas power plants. Unfortunately, still more than 70 percent of electricity and even more thermal energy is generated in Poland in conventional thermal power plants powered by coal or lignite. Successively from year to year, as part of the progressive green transformation of the energy industry, the share of various types of renewable energy sources in the energy mix of energy sources is steadily increasing.

I described the key issues of the green transformation of the economy, including the green transformation of the energy sector, in my article below:

How to develop investments in renewable energy sources?

It is tough to estimate this for India and yes if it is only Renewable Energy Targets then its very easy and the answer is YES for India when it comes to Biogas we need to look deeper into the subject and a tough call based on the present progress in the Biogas Industry in India

Why is this year (2024) warmer in Iran as well as in the northern hemisphere compared to previous years?

In general, warm air penetrates from hot and tropical regions to temperate and polar regions. Based on synoponic hydrology and meteorology, the regions are divided into two categories of low pressure or high pressure, or into low pressure and high pressure regions. All of the Earth's atmosphere is in the general circulation of the atmosphere. Now why this summer season, especially in 2024, grammar is getting hotter and hotter than the time series of the last 30 years. According to the book published in the past years based on the findings of my master's thesis entitled "Clocking of time series in the plateau of Iran" which was investigated in the northeastern region of Iran and the zoning maps of rainfall and drought based on my data. I got an organization. . The country's meteorology was investigated for 40 years (1353-1393) and its graphs were extracted for drought spi index and drought periods of 6, 12, 24, 48 months and also based on clustering and factor analysis it was determined that the dynamic reason in Bandoli or blocking systems definitely occur in Siberia and the Tibetan and Pamir plateaus in northeastern Iran, and this type of system exists in different seasons such as autumn and winter, such as rex block and double ring block. Blocking ring and fire ring systems. Or in the form of a high-pressure front in the shape of an omega, which causes cold and rain, blocks the northeast of Iran and rains in the northwest of Iran. In the northwestern provinces of Iran, such as Ardabil and Azerbaijan, we have rainfall, but in the east, especially in the northeastern part of Iran, the rainfall is less, and in provinces such as Tehran, due to the foothills of the region, only the foothills are cool. In the summer season, they have experienced the high temperature and humidity of monsoon regions. They will empty the tropical seas and oceans in the southern regions of Iran to the center of Iran, which will be mostly torrential rains. Now the question is, why is the weather warmer this year? Will next year be hotter than this year? And how many years will this process continue? According to most climate researchers, this trend is increasing until the year 2100 and climate change is certain and this climate change is caused by human activities for the planet. It is like the development of industrial centers in the world and the destruction of forests and pastures and the change of agricultural land use. And the other is the increase of gasoline cars. Also, people in agricultural areas build villas instead of agricultural land, which means changing the use of agricultural land and also increasing animal husbandry, especially animal husbandry, which emits more methane than sheep. Also, agricultural products such as planting rice produce methane gas. And in rice cultivation, the production of methane gas occurs, which helps to increase greenhouse gases on the planet and has become hotter with the increase in global warming and the upward trend and due to the penetration of long waves. The sun's radiation to the earth's atmosphere, which makes it warmer when it enters the earth's atmosphere, the presence of greenhouse gases cannot quickly enter the long wavelength of the sun's rays into the earth's atmosphere, because due to the wavelength of the sun's radiation, the sun's long wave in The atmosphere is trapped and has a great effect in intensifying the heat of the earth's surface, and most climatologists believe that human behavior is effective in climate change activities on the planet. Such as changing the exhaust system of acidic and toxic gases of cars and using clean and renewable energies and developing forests instead. All the climate systems of the world interact with 5 climate systems, that is, if one of them changes, the rest of the ecological and climate systems will also be destroyed, so 5 systems: 1-Atmosphere. 2- Biosphere 3- Water sphere 4- Rock sphere 5- Icy sphere and human role in creating this system should be properly investigated and this global warming will not be corrected unless selfish and proud people only think of making weapons and killing innocent people. About the nature and climate of the earth. Consider saving the planet and climate change important. And let them know that we are alone in this world and existence, and if one day this planet becomes uninhabitable due to the ignorance of humans, we humans will no longer be able to live on it and we will not be able to travel to it. . Another planet, so let's pay more attention to our beloved planet. And to love and respect the planet Earth more.

According to recent studies, the rate of global warming due to human activity has reached record highs. The highest rate of global warming since record-keeping began is 0.26 degrees Celsius per decade, according to research by more than 50 scientists.

Data has also shown that January 2024 experienced a record-breaking global ocean surface temperature for the tenth consecutive month. According to forecasts by the National Center for Environmental Information (NCEI), there's a 99% chance that 2024 will be among the five hottest years on record.

Moreover, many of the world's leading climate scientists predict that global temperatures will rise to at least 2.5 degrees Celsius above pre-industrial levels during this century. This far exceeds the Paris Climate Agreement's target to limit global temperature increases to 1.5 degrees Celsius.

This data underscores the urgent need to take immediate and effective action to reduce greenhouse gas emissions and adapt to the effects of climate change.

Yes, this information applies to Iraq as well, as climate change is a global phenomenon affecting all countries, including Iraq. In fact, Iraq is considered one of the countries most affected by climate change in the Middle East region. Here are some specific points about Iraq's:

Therefore, the urgent need to take effective measures to adapt to the effects of climate change and reduce greenhouse gas emissions greatly applies to Iraq

The unusually hot weather experienced in Iran and the Northern Hemisphere in 2024 could be attributed to several factors, often interrelated: Climate Change: The long-term trend of rising global temperatures due to increased greenhouse gas emissions is a major factor. This trend is causing more frequent and intense heatwaves, altering weather patterns, and contributing to hotter summers. El Niño: The El Niño-Southern Oscillation (ENSO) is a climate phenomenon that affects global weather patterns. During an El Niño event, sea surface temperatures in the central and eastern Pacific Ocean rise, influencing global temperatures and potentially leading to hotter conditions in various regions, including the Northern Hemisphere. Heatwaves: Specific periods of extreme heat can occur due to weather systems that trap warm air in a region, leading to prolonged periods of high temperatures. These systems can be exacerbated by changes in the jet stream, which may be influenced by global warming and Arctic ice loss. Urbanization: Increasing urbanization, particularly in densely populated areas, can contribute to higher local temperatures. The "urban heat island" effect occurs because concrete, asphalt, and other materials absorb and retain heat more than natural landscapes, leading to higher temperatures in urban areas. Natural Variability: Year-to-year variations in weather can also play a role. Natural climate cycles and random weather variations can lead to some years being hotter or colder than others, independent of long-term climate trends. Changes in Land Use: Deforestation, agricultural practices, and other changes in land use can influence local climates and contribute to rising temperatures.

I am an undergraduate mechanical engineering student seeking suggestions on topics related to either thermodynamics, fluid mechanics, heat transfer or renewable energy for my final year project. The topics I have found require a higher level of education. I am trying to bring it down to an undergraduate level, however I am hoping that new suggestions might shed more light or spark a new interest.

Thank you in advance.

Can anyone give me some typical values for total inorganic carbon (TIC mol HCO3/m3) and for alkalinity (cations Scat eq/m3) to use as input for activated sludge anaerobic digestion modelling with ADM1?

The realization of sustainable development goals, the implementation of climate and environmental policies, the implementation of the green economy transformation process, etc. the goal of building a sustainable, emission-free, green closed-loop economy is, among other things, to rapidly reduce greenhouse gas emissions going into the atmosphere until the economy becomes emission-free, so that the planet's greenhouse effect process is effectively reduced and baby the progressive process of global warming slows down. However, since the key negative effects of the progressive process of global warming include increasingly severe droughts, higher and higher temperatures during summer heat waves, acceleration of soil aridity, more frequent forest fires but also sometimes unusual weather anomalies, violent storms with torrential downpours causing flooding and sometimes problematic floods, so the implementation of the process of green transformation of the economy becomes a key element in the systemic protection of the biodiversity of the planet's natural ecosystems as well. In recent years, new ICT and Industry 4.0/5.0, including Internet of Things technologies, cloud computing, multi-criteria simulation models, digital twins, smart technologies, Big Data Analytics, Business Intelligence analytical and reporting systems, machine learning, deep learning, generative artificial intelligence, are being applied in improving techniques for monitoring the state of the planet's natural ecosystems and developing techniques for protecting the biodiversity of natural ecosystems.

In April 2024, the European Union reached a historically record level of 33.8 percent share of clean energy. Wind and solar power dominated this share in terms of RES energy generated. There is still a high level of variation across countries in the European Union in the share of clean energy based on renewable and zero-emission energy sources.

In Norway, for example, the share of clean energy from RES is as high as 98 percent on average, while in Poland it is only 27.1 percent. In April 2024, only about one-third of the energy generated in the European Union came from dirty energy based on combustion power, where energy was generated from burning fossil fuels, mainly coal, lignite and gas.

In April 2024, Poland, too, saw a historically record amount of energy generated from RES at 30 percent of the total energy mix. Solar and wind power dominated this 30 percent of renewable and carbon-free energy sources. From wind it was half of this 30 percent. However, due to insufficient investments made over the last few decades of time in the development of transmission grids, much of this energy generated from wind and solar, i.e. from the cheapest sources of energy and at the same time clean, emission-free energy, was not accepted by power companies from prosumers and simply went to waste. Since there are large losses of produced and unused energy from RES sources, it means that the investments made earlier in the development of emission-free and renewable energy sources are also partially wasted. In Poland, the large power companies dominating the energy sector, which still generate energy mainly through combustion power from burning coal and lignite, invest too little in the development of transmission networks and storage facilities for the energy generated. However, thanks to the financial subsidies unblocked by the European Union, also granted to Poland as part of the National Economic Recovery Plan after the pandemic economic crisis of 2020, it will be possible to accelerate the processes of green energy transformation. A large part of the European Union countries have already benefited from these subsidies for 2 years.

I have described the key issues concerning the problems of green transformation of the economy in the following article:

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.

Imagine the WCED 1987 would have set only one sustainable development goal, closing the renewable energy technology gap to make renewable energy a permanent substitute of non-renewable energy as soon as possible and address pollution production head on by transitioning out of dirty economies.

Imagine 2012 RIO +20 would have made only one goal to support the implementation of green markets, to set up a system around implementation, financing, and monitoring of the closing of the renewable energy technology gap in each country as soon as possible to address pollution reduction head on by making pollution reduction a profit-making opportunity.

Imagine the 2015 Paris agreement had only one goal implemented in a socially friendly manner, to close the renewable energy technology gap as soon as possible to lead the dirty economy behind and stop providing benefits to those making money from dirty development.

Instead, attention has been placed on managing the consequences of pollution production markets which keeps renewable energy as a permanent complement and send dirty markets under permanent dirty market failure.

And this raises the question, should making renewable energy a permanent substitute be a clear and practical SDG goal?

What do you think?

Advanced analytical systems, including complex forecasting models that enable multi-criteria, highly sophisticated, big data and information processing-based forecasts of the development of multi-faceted climatic, natural, social, economic and other processes are increasingly based on new Industry 4.0/5.0 technologies, including Big Data Analytics and machine learning, deep learning and generative artificial intelligence. The use of generative artificial intelligence technologies enables the application of complex data processing algorithms according to precisely defined assumptions and human-defined factors. The use of computerized, integrated business intelligence information systems allows real-time analysis on the basis of continuously updated data provided and the generation of reports, reports, expert opinions in accordance with the defined formulas for such studies. The use of digital twin technology allows computers to build simulations of complex, multi-faceted, prognosticated processes in accordance with defined scenarios of the potential possibility of these processes occurring in the future. In this regard, it is also important to determine the probability of occurrence in the future of several different defined and characterized scenarios of developments, specific processes, phenomena, etc. In this regard, Business Intelligence analytics should also make it possible to precisely determine the level of probability of the occurrence of a certain phenomenon, the operation of a process, the appearance of described effects, including those classified as opportunities and threats to the future development of the situation. Besides, Business Intelligence analytics should enable precise quantitative estimation of the scale of influence of positive and negative effects of the operation of certain processes, as well as factors acting on these processes and determinants conditioning the realization of certain scenarios of situation development. Cloud computing makes it possible, on the one hand, to update the database with new data and information from various institutions, think tanks, research institutes, companies and enterprises operating within a selected sector or industry of the economy, and, on the other hand, to enable simultaneous use of a database updated in this way by many beneficiaries, many business entities and/or, for example, also by many Internet users in a situation where the said database would be made available on the Internet. In a situation where Internet of Things technology is applied, it would be possible to access the said database from the level of various types of devices equipped with Internet access. The application of Blockchain technology makes it possible to increase the scale of cybersecurity of the transfer of data sent to the database and Big Data information as part of the updating of the collected data and as part of the use of the analytical system thus built by external entities. The use of machine learning and/or deep learning technologies in conjunction with artificial neural networks makes it possible to train an AI-based system to perform multi-criteria analysis, build multi-criteria simulation models, etc. in the way a human would. In order for such complex analytical systems that process large amounts of data and information to work efficiently it is a good solution to use state-of-the-art super quantum computers characterized by high computing power to process huge amounts of data in a short time. A center for multi-criteria analysis of large data sets built in this way can occupy quite a large floor space equipped with many servers. Due to the necessary cooling and ventilation system and security considerations, this kind of server room can be built underground. while due to the large amounts of electricity absorbed by this kind of big data analytics center, it is a good solution to build a power plant nearby to supply power to the said data center. If this kind of data analytics center is to be described as sustainable, in line with the trends of sustainable development and green transformation of the economy, so the power plant powering the data analytics center should generate electricity from renewable energy sources, e.g. from photovoltaic panels, windmills and/or other renewable and emission-free energy sources of such a situation, i.e., when a data analytics center that processes multi-criteria Big Data and Big Data Analytics information is powered by renewable and emission-free energy sources then it can be described as sustainable, pro-climate, pro-environment, green, etc. Besides, when the Big Data Analytics analytics center is equipped with advanced generative artificial intelligence technology and is powered by renewable and emission-free energy sources then the AI technology used can also be described as sustainable, pro-climate, pro-environment, green, etc. On the other hand, the Big Data Analytics center can be used to conduct multi-criteria analysis and build multi-faceted simulations of complex climatic, natural, economic, social processes, etc. with the aim of, for example. to develop scenarios of future development of processes observed up to now, to create simulations of continuation in the future of diagnosed historical trends, to develop different variants of scenarios of situation development according to the occurrence of certain determinants, to determine the probability of occurrence of said determinants, to estimate the scale of influence of external factors, the scale of potential materialization of certain categories of risk, the possibility of the occurrence of certain opportunities and threats, estimation of the level of probability of materialization of the various variants of scenarios, in which the potential continuation of the diagnosed trends was characterized for the processes under study, including the processes of sustainable development, green transformation of the economy, implementation of sustainable development goals, etc. Accordingly, the data analytical center built in this way can, on the one hand, be described as sustainable, since it is powered by renewable and emission-free energy sources. In addition to this, the data analytical center can also be helpful in building simulations of complex multi-criteria processes, including the continuation of certain trends of determinants influencing the said processes and the factors co-creating them, which concern the potential development of sustainable processes, e.g. economic, i.e. concerning sustainable economic development. Therefore, the data analytical center built in this way can be helpful, for example, in developing a complex, multifactor simulation of the progressive global warming process in subsequent years, the occurrence in the future of the negative effects of the deepening scale of climate change, the negative impact of these processes on the economy, but also to forecast and develop simulations of the future process of carrying out a pro-environmental and pro-climate transformation of the classic growth, brown, linear economy of excess to a sustainable, green, zero-carbon zero-growth and closed-loop economy. So, the sustainable data analytical center built in this way will be able to be defined as sustainable due to the supply of renewable and zero-carbon energy sources, but will also be helpful in developing simulations of future processes of green transformation of the economy carried out according to certain assumptions, defined determinants, estimated probability of occurrence of certain impact factors and conditions, etc. orz estimating costs, gains and losses, opportunities and threats, identifying risk factors, particular categories of risks and estimating the feasibility of the defined scenarios of the green transformation of the economy planned to be implemented. In this way, a sustainable data analytical center can also be of great help in the smooth and rapid implementation of the green transformation of the economy.

In 2022, the scale of sales of heat pumps in Poland increased by approximately 100 per cent compared to the previous year. This was due to the energy crisis generated by the slowing down of the development of renewable and emission-free energy sources by the PIS party currently in power over the past eight years and the promotion of energy development based mainly on burning combustible fuels, mainly coal and lignite. As a result, three quarters of Poland's electricity generation and even more of its heat generation is still based on burning coal. As a result, when the price of fossil fuels rose sharply between 2021 and 2022, the cost of living for many citizens increased by several tens of percent. The solution to the problem of rising heating and energy costs was to install heat pumps powered by electricity from photovoltaic panels installed on the roof or next to the house, or other renewable energy sources. However, these other alternative renewable and emission-free energy sources are few and far between due to energy policy. In order to increase the energy savings of their homes, many citizens would like to insulate their homes by renovating and adding insulation to the facades of their buildings. It is estimated that over 4 million residential homes in Poland lack thermal insulation. However, this is unfortunately not possible due to the overly limited financial programmes of non-refundable subsidies with which such investment projects could be financed. Many citizens, despite the fact that they would like, for example, to power heat pumps with electricity from a wind turbine, a windmill erected close to their home, have not had this opportunity because in 2016 the PIS government blocked the development of wind energy in Poland by passing the so-called 10h Law. Similarly, in April 2022, a change in the regulation of billing for photovoltaic panels installed on the roof or next to a residential house by citizens prosumers of their own electricity made these installations unprofitable and the number of new installations of this kind fell by three quarters. When the development of wind power in Poland was blocked in 2016, coal imports increased strongly. In addition, nuclear power and other fully renewable energy sources were not developed. The result is a low level of independence and energy security for the country. Besides, the result is one of the lowest air quality and high levels of smog in cities during the heating season in international rankings. Unfortunately, despite the existence of new renewable energy technologies whose application on a larger scale could solve the above problems, the scale of development of governmental and self-governmental programmes of financial subsidies and support from the European Union is still too small. And it is too small because Poland has not met the so-called milestones set by the European Commission and is the only country in the EU which has not received financial subsidies under the National Reconstruction Programme. One of these milestones is the issue of unblocking the onshore wind energy development previously blocked in 2016. Currently, i.e. in Q1. 2023, a law is being processed to unblock this issue. However, the still ruling PIS party, as part of its support for the development of coal-fired power generation and its support for government-controlled, monopolistically operating energy and fuel companies of the state treasury, included in the aforementioned law provisions that in practice limit the development of onshore wind energy (a minimum distance of 700 m between a windmill and the nearest buildings) so that only a few per cent of the country's area can be covered by these windmills. This means that a small proportion of willing citizens will benefit from this, and it will benefit mainly and also to a limited extent the government-controlled, monopolistically operating energy state companies. Thus the circle of this travesty of energy, climate and environmental pseudo-politics is closing. In view of the above, technological solutions that could solve the above problems are already available, but the national pseudo-politics of energy, climate and environment causes that the development of renewable and emission-free sources of energy, improvement of energy security, reduction of the scale of the energy crisis, improvement of air quality in cities is still being slowed down, the goals of sustainable development are being ignored by the PIS government, and the green transformation of the economy, achieving zero-emission of the economy, building a sustainable economy in accordance with counteracting the progressive process of global warming is progressing much slower than it could be.
