I think that the process of real discussions has begun and the scientific work of the participants in this discussion will make progress in alternative energy.

The future is for alternative energy and if not invent such consequences.

If do not think now about the future what will happen if run out of hydrocarbon fuel.

Alternative energy is the future of the planet and I think they are not experts in their field.

Internal combustion Engines also suffer from pinking or knocking which can be stabilized. Alternative Energy can still go beyond these issues with the aid of more research but it's definitely the future

Thanks for the comments.

I do not understand the words "alternative energy". Do it mean forget and ban fossil fuels and decide that nothing, but solar (including PV's, Wind, Biomass, ...) energy sources, are sustainability-compliant ?

If so, I am afraid that it would accelerate the move to much higher temperatures than the 2°5 expected from the COP21 Agreement (Paris 2015).

However, there is another way, not a Plan B : Let us ask our governments, energy industry managers, NGP's activists, ... to really promote Energy Efficiency as a major Energy Source. It is being demonstrated, since more than 40 years in a very real State where it results in a 40 % energy decrease, lower CO2 emissions rate and a higher GDP

Anyone wants more info is kindly invited to send me any request ot question about this

Very Best Regards

Jacques Roturier

Monsieur Jacques I appreciate your feedback and your decision makes sense.

Waiting for your feedback.

Alternative energy is the solution to environmental problems and all obstacles will be eliminated by scientific means.

Despite all the negative statements of opponents, I will vote for alternative energy. The most powerful solar power plant Topaz, located in California and is the largest solar power plant in the world with a capacity of 550 MW, and allows you to reduce carbon dioxide emissions into the atmosphere by at least 380 thousand tons per year.

Perpetual motion does not exist but the action at the expense of alternative energy is real. I'm for alternative energy.

Toxic can be and tomatoes which we consume, technologies are updated and these shortcomings will be eliminated and alternative energy is developing.

Dear Colleagues and Friends from RG,

Due to the progressing faster and faster global warming process, sustainable pro-ecological development is a must. Therefore, it is necessary to develop energy based on renewable energy sources. However, still few pro-ecological activities are undertaken to increase the possibilities of achieving fully sustainable pro-ecological economic development conducted in accordance with the green economy philosophy. The above discussion inspired me to formulate the following questions: Should the pursuit of fully sustainable ecological development become the greatest challenge for humanity and goal # 1 of the development of 21st century civilization? Is the main determinant enabling the achievement of this important goal the efficient process of implementing environmentally friendly reforms in the energy sectors, consisting mainly in the rapid development of renewable energy sources? How can the effectiveness of renewable energy development programs be increased?

On the basis of the above considerations and conclusions from the discussion on interesting issues discussed, I formulated the following thesis that the pursuit of achieving fully sustainable pro-ecological development should become the greatest challenge for humanity and No. 1 development of the 21st century civilization. The main determinant enabling the achievement of this important goal is the efficient process of implementing environmentally friendly reforms in the energy sectors, consisting mainly in the rapid development of renewable energy sources. Below I have described the key determinants confirming the formulated research thesis. To the above discussion I would like to add the following conclusion formulated as a summary of my earlier considerations on this topic: determinants of the possibility of achieving fully sustainable pro-ecological development.

Due to the progressing faster and faster global warming process, sustainable pro-ecological development is a must. However, still few pro-ecological activities are undertaken to increase the possibilities of achieving fully sustainable pro-ecological economic development conducted in accordance with the green economy philosophy. In my opinion, sustainable ecological development is a must. It is a key challenge of the 21st century. In connection with the growing pollution of the environment, the increase in greenhouse gas emissions, the accelerating process of global warming, if humanity is interested in protecting life on Earth, maintaining biodiversity for subsequent generations, the 21st century should be the age of technology development and innovations, including ecological ones, and economic development should be implemented according to the principles of green economy, in order to achieve sustainable ecological development in the shortest possible time.

Climatologists and scientists from other fields of science, conducting research on climate change and its effects, develop long-term forecasts of these changes. These forecasts show that the continuation of the global warming process over the next few decades may lead to the thaw of permafrost at the Arctic Circle and the release of millions of tons of frozen methane. Then the global warming process will accelerate and the Antarctic meltdown will be unstoppable. The areas in which man will be able to live and live due to the melting of all glaciers and due to the drying of many areas currently covered with vegetation or used for agriculture in the tropical and subtropical zones will decrease. It is also possible to increase Earth's seismic activity, increase in volcanic eruptions. The reason may also be an increase in the activity of the Sun over a period of several dozen years, because the current activity of the Sun is low.

The intensification of these processes in the second half of the 21st century is probably already inevitable. Is human therefore also an endangered species due to the increasingly rapid global warming process? If the average temperature at the Earth's surface by the end of the 21st century increases by another min. 3-4 degrees C is the scale of climate change, weather anomalies and climate disasters will be so large that the human species will be classified as endangered species. However, humanity should try to slow down the process of global warming, the more that since the acceleration of the process of global warming since the nineteenth century, i.e. since the industrial revolution based on the invention of the steam engine man is responsible. The period of the next dozen or so years, especially the period up to about 2030, is the most important, key for the implementation of necessary pro-ecological reforms, including the transition of the entire energy sector to renewable energy sources. In addition, the development of electromobility, improvement of waste segregation and recycling, development of ecological agriculture, afforestation of areas degraded by industry, irrigation of drought areas, etc. are necessary elements of pro-ecological activities that are important elements in achieving sustainable ecological development, including the transformation of classic economics in green economy.

In my opinion, since the end of the 19th century, i.e. since the end of the industrial revolution and the beginning of the second technological revolution based on electricity, the development of pro-ecological technologies has been neglected. Sustainable ecological development should be built from the 19th century and not over 100 years later. At the end of the 19th century, the first electric battery technologies were developed. The first motor vehicles, the first Ford cars were electric and instead of developing electromobility at that time, combustion engine technologies began to be developed. Military operations of the 20th century only consolidated these unfavorable trends in the development of combustion technology. And now we are starting to experience a faster and faster global warming process, which is the result of greenhouse gas emissions increasing since the 19th century. For more than 100 years, humanity has neglected the development of pro-ecological technologies, including primarily energy based on renewable energy sources. If sustainable economic development based on green economy began to develop from the nineteenth century, now the world would look completely different and in the twenty-first century there would be no serious problems related to man-made climate change.

When economics arose many years ago as a separate field of knowledge and science, the precursors of classical economics believed that in the future the world would develop in a nearly balanced way thanks to full free competition operating nationally and internationally. Unfortunately, it happened differently. Civilization development is increasingly diverging from sustainable. Therefore, the question now is whether it is possible to return to fully sustainable ecological growth in national, international and global terms. Is the level of imbalance already so high that perhaps it is not possible to change towards the implementation of fully sustainable proecological economic development?

I believe that it cannot be said that this will never be possible. Regardless of the current state of economic development in the world, the scale of environmental degradation, the progressing global warming process, the increasing diversity in the income and standard of living of citizens, many industries need to be reformed and the free development of markets on a national and international scale should be developed, and sustainable ecological principles should be implemented development to business processes. Large, supranational manufacturing, service, financial, etc. corporations, which often have a large impact on globalization processes and on the development of individual countries, should also be subordinated to these principles. Sustainable ecological development is the biggest challenge to be implemented in the 21st century. The implementation of sustainable pro-ecological development in business processes will change traditional classic economy into green economy. The most important question that arises in this matter, the key question for humanity in the 21st century: Will man manage to change traditional classical economy into a green economy before the global warming process, which is progressing faster and faster, deprives most of the land's surface of life for humans and flora and fauna?

Unfortunately, however, there are still serious barriers to financing renewable energy sources. Unfortunately, conventional technologies in many industries and industrial sectors still dominate in many countries. For example, in my country currently only 15 percent. electricity is generated from renewable energy sources and the remaining 85% from traditional energy based on mineral combustion. By 2030, it is planned to increase the share of electricity production from renewable energy sources to 32 percent. This is not much considering that in many countries this plan is set at a minimum of 50 percent. energy production from renewable energy sources in 2030. In addition, an important determinant of the necessary pro-ecological reforms in the energy sector that should be implemented in the next decade is the problem of rapidly growing greenhouse gas emissions in recent years, the global warming process that is progressing more rapidly, and the resulting weather anomalies and climatic disasters that are increasingly common including forest fires, drought in green areas and agriculture, melting glaciers, flooding in coastal areas, etc.

On the other hand, in some countries green technologies are increasingly being developed. Commercial companies and public institutions financed or co-financed from subsidies received from the state's public finance system participate in this process. These processes are usually inspired, initiated and co-financed by the state. Ecological innovations are increasingly being developed as part of the system of implementing the principles of sustainable pro-ecological economic development conducted according to the concept of green economy and projects as well as pro-ecological reforms financed from green finance funds. The development of green technologies is important because every day in many media there is more information about the growing scale of devastation of the natural environment through the development of human civilization. In recent years, environmental pollution has been increasing and the global warming process is increasing rapidly.

Research conducted for many years by climatologists confirms that the global warming process is mainly caused by an increase in greenhouse gas emissions generated by the energy sector based on classic energy generating electricity from mineral combustion and the automotive industry also based on internal combustion engines. In addition, innovations in the field of renewable energy sources should be created and implemented as soon as possible. The energy sector should be changed as soon as possible and reformed in order to develop renewable energy sources. Classic energy sources based on the combustion of minerals should be replaced by energy technologies based on renewable energy sources, i.e. first of all solar, wind, water and possibly also nuclear energy should be developed. Therefore, in the context of increasingly faster climate change processes, accelerating the global warming process, increasing pollution of the natural environment, international financing systems for pro-ecological projects should be created. Within these systems, international institutions should be created to finance projects for implementing ecological reforms, creating and implementing eco-innovation, etc. Grants should be awarded for research projects in the field of renewable energy development.

In connection with the above, it is necessary to increase expenditure in all countries on ecological reforms in order to implement the principles of sustainable ecological development according to the green economy philosophy. In addition, international financing systems for the creation and implementation of green innovations and green reforms should be developed in many branches of modern economies, primarily in energy through the development of renewable energy sources. National and international systems for financing pro-ecological reforms in the green finance formula should be developed. The next several years is the last moment to carry out the necessary ecological reforms to avoid a chain reaction of increasing climatic disasters and reduce the scale of environmental pollution and protect most of the remaining biosphere, biodiversity from irreversible degradation. Therefore, humanity should reduce greenhouse gas emissions as soon as possible, energy based on renewable energy sources, electromobility, organic farming, waste sorting, recycling, etc. should be developed. Therefore, financial outlays for creating new ecological innovations, green technologies and their implementation in industry. However, despite the obvious need to increase expenditure on renewable energy sources, unfortunately in recent years to a significant and sufficient extent as required, these expenditures do not grow in many countries.

The above discussion shows that the state should support and activate the development of entrepreneurship and innovation. Supporting and activating the development of entrepreneurship and innovation is particularly important in developing countries and in a situation of weakening economic growth. In addition, in the context of increasingly intensifying climate change, increasingly faster global warming processes, the importance of supporting the development of entrepreneurship and innovation by the state from public funds in the field of creating and implementing ecological innovations, e.g. in the field of renewable energy sources, electromobility, automation of segregation processes is also growing waste, improving recycling logistics, developing ecological agriculture, improving wastewater treatment techniques and reclamation of the natural environment, etc., and activating entrepreneurship in these areas of pro-ecological economic activity. By supporting and activating the development of entrepreneurship and innovation in enterprises and creating, implementing ecological innovations, the state can accelerate the processes of implementing the principles of pro-ecological economic development conducted in accordance with the green economy philosophy and financing pro-ecological programs from public green finance funds. Through this activation, a significant part of the economy should be transformed into sustainable ecological development directions, which will result in the development of cooperating enterprises, subcontractors, suppliers of prefabricated, semi-finished and ecological raw materials in commercially functioning sectors of the economy.

Therefore, economic development according to classical economy should be transformed into sustainable pro-ecological development according to green economy. In the context of increasingly faster climate change processes, increasing pollution of the natural environment, it is necessary to implement the principles of sustainable pro-ecological development as soon as possible in accordance with the green economy philosophy and to finance pro-ecological reforms from green finance sources. Time is short. It is not certain that humanity will completely reduce its greenhouse gas emissions to zero by 2050. It is also not certain that if humanity succeeds, the global warming process will cease to deepen.

However, implementing the principles of sustainable pro-ecological development is a necessity and the biggest challenge in the 21st century. Therefore, high economic growth should no longer be a priority, but just the implementation of sustainable development principles in line with the green economy philosophy and financing of green reforms from green finance sources. Grants should be awarded for research projects in the field of biodiversity protection. National and international financing systems for the creation and implementation of pro-ecological innovations and pro-ecological reforms in many branches of modern economies should be developed, primarily in the energy sector through the development of renewable energy sources. National and international systems for financing pro-ecological reforms in the green finance formula should be developed.

In line with the above, in my opinion, the pursuit of fully sustainable ecological development should become the greatest challenge for humanity and the # 1 development goal of the 21st century civilization. The main determinant enabling the achievement of this important goal is the efficient process of implementing environmentally friendly reforms in the energy sectors, consisting mainly in the rapid development of renewable energy sources.

Do you agree with me on the above matter?

Thanks for the recommendation Mr. Mykhailo Illich Fyk appreciate your feedback.

Biofuels are a very promising source of energy, literally grown in the fields. It is extracted from vegetable oils-for example, soy or corn. But the most promising are... algae, giving a hundred times more resources than terrestrial plants. And even the waste from them can be used as fertilizer.

Alternative energy source – a method, device or structure that allows to obtain electrical energy (or other required type of energy) and replaces traditional energy sources that operate on oil, produced natural gas and coal.Solar energy is the conversion of solar energy into electricity by photovoltaic and thermodynamic methods. For the photovoltaic method, photovoltaic converters (FEP) are used with the direct conversion of the energy of light quanta (photons) into electricity.

We should think of reusing the toxic batteries instead of disposal......

Along with the above techniques we can use RF energy harvesting, pressure energy harvesting, gas energy harvesting and etc....

The world uses about 600 exajouiles (EJ) of energy annually, and all energy is not equal. Coal, oil and natural gas currently account for 89% of the total, or about 480 EJ. Oil is the most valuable and versatile energy source because it can generate electricity, power all forms of transportation—air, road and off-road for the farmer who grows your food. (Think of how important oil is to helping us react to natural and otter disasters.) Coal and natural gas are not as flexible but can be converted to liquid fuels. Fossil fuels are also an important source of chemicals and fertilizers.

Wind and solar can only generate electricity and then only sometimes—they are not robust or reliable. Solar hot water heating is a small but effective use of solar energy.

Nuclear fission is a robust and reliable source of heat and electricity. It is the safest way to generate the large quantities of electricity the world cannot live without. Nuclear fuel is available for tens of thousands of years.

We need to use nuclear generated electricity wherever we can and save oil,. coal and natural gas for applications where only they can perform as necessary.

There are no easy or simple solutions to replacing fossil fuels, which are stored solar energy accumulated over millions of years.

Hope this helps.

H. Douglas Lightfoot

Thank you, Mr. Douglas, and look forward to your new proposals.

the total amount of electricity generated by wind, solar and hydroelectric power plants was about half of the total amount of energy produced in the country. If we add nuclear power plants, we can say that over the past week, energy sources with low carbon production gave the region 72.1% of all electricity produced during this period of time. However, it is not necessary to talk about nuclear power plants as an alternative source of energy.

In many European countries, the whole week was Sunny and windy, which made it possible to obtain a large amount of "green" energy, especially in the Northern part of the region. Officials in the UK said: "for the First time ever, wind, nuclear and solar power plants have generated more energy than thermal power." In the same UK last Tuesday, wind farms produced about 10% of the total electricity. First of all, we are talking about onshore wind farms.

You just emphasized the fact that wind relies of weather conditions. When the wind does not have enough speed or the sun does not shine, both wind and solar are zeroes.

There are no easy or simple solutions to replacing fossil fuels. If we are careful and use fossil fuels only where necessary, maybe we have up to a century to find solutions. At present there are no solutions on the technology horizon.

For reference, when Hurricane Harvey hit the Gulf Coast of the U.S., it shut down the wind farms, the solar plants, the coal fired plants and the natural gas fired plants. Only the nuclear power plant continued to supply electricity during the storm. Nuclear energy is the strongest, safest and most reliable way to generate the large quantities of electricity we need for modern society. No one can prove that wrong!

Most people make the mistake of ignoring the concept of scale when discussing energy as well as the fact that all energy sources are not equal.

Thank you for your feedback and I appreciate your answers. Waiting for new offers

Many of the solutions must and will need chemistry.

Article AGENDA 2030: A Challenge for Chemical Science and industry

Recycling of toxic waste whatever they were not always time-consuming and expensive procedure. Therefore, it is better to use batteries that do not contain toxic elements. Scientists from USC (University of Southern California) have created low-cost flow batteries ORBAT (Organic Redox Flow Battery) for large-scale energy storage systems in power plants. Of course, they are also suitable for household energy storage systems, as well as for systems with renewable energy sources.The new batteries are designed on durable materials that do not contain metals and toxic elements. "The battery life is about 5000 recharge cycles, and is estimated to have a 15-year service life.

Batteries are simply not a solution as back-up to a large power plant. They are simply too low energy density and discharge rate is a problem. For example, a pumped storage plant in Slovakia can add 1,000 MW to a grid in about one minute and remove 1,000 MW in about two minutes. This is realistic to provide a stable electricity supply during peak periods.

Wind and solar are the least viable sources of electricity to supply a grid. Solar has some useful applications for small scale systems. For example, solar heating for hot water is one of the best applications of solar energy. Solar PV is also useful where very small amounts of electricity are required, such as for calculators and signs.

Chemical energy storage batteries have reached their upper physical limit. If batteries are to play a larger role in the energy system, we need an entirely new approach to supplying electricity. So far, there appears to be nothing in sight.

The performance of computers and smartphones are improving because over time, the circuits require less and less electricity. The energy density of the batteries has not increased significantly.

H. Douglas Lightfoot

Thank you for your feedback and I appreciate your answers. Waiting for new offers

Considering the evolution of solar energy, buildings and houses could be transformed in the future into individual power stations and could not need electricity from the grid although remaining connected to a grid for power optimization and safety reasons.

The concept of individual building and houses being individual power plants appears reasonable until one actually starts trying to make it happen. How much sun is available on specific buildings and houses considering shading from adjacent buildings and the north/south orientation of the structure? Apart from the overwhelming technical difficulties, there is the inconvenience to people—everyone must become a power plant operator and maintenance person. It is much easier for people if they are connected to a grid.

Being connected to a grid for any reason attracts a charge because the grid must be operated and maintained. Distributed power generation has been suggested for a long time and has basically gone nowhere because of the serious problems associated with it.

H. Douglas Lightfoot

Of course this is a big change but I disagree that everybody must be a power plant operator. For an optimal energy balance the buildings would not be separated from the grid as I said. So if they have not anough power, the difference comes from the grid and when there is an excess it goes to the grid. Of course organization must change but the management of the system would be mainly by professionals of the grid companies. Filling landscapes with solar panels is not the best solution, especially if they occupy much surface and space and are replacing or impeding forestation. The best place for solar power plants are the deserts. Morroco is a good example. Look here: https://en.wikipedia.org/wiki/Solar_power_in_Morocco

I am also a supporter of personal solar power, but this does not mean that specialists will not work. Let them install and maintain it for the money I pay them.

In the third Millennium, humanity finally began to understand that no one can guarantee that the planet will be all right. The future depends on human decisions and actions. Realizing this, people tried to consolidate their new worldview in regulations: the Paris agreement on climate was adopted, and in the national legislation of many countries there were rules designed to regulate the harmful effects of humans on nature. The natural reaction to the new reality is the development of carbon-free energy, that is, power plants that do not use organic fuel and do not emit greenhouse gases. The oldest branch of such energy, which initially competed with thermal power plants since the XIX century, is hydropower. But in a strange way, the criticism of environmental organizations that call for denying them the status of a "true renewable energy source"is often focused on hydropower. During the construction of a hydroelectric power station, the terrestrial ecosystem is replaced by the reservoir ecosystem, which is very similar to the ecosystem of natural lakes, adjusted for the reservoir's youth. Replacing one natural ecosystem with another is a modification, not a destruction (as happens, for example, when developing a coal pit). Often, the creation of a new reservoir objectively enriches the landscape and increases the biodiversity of the territory as a whole.

There are no problems with geothermal heating / cooling systems, except you need a small amount of energy to power the heat pump.

The energy is obtained from the ground, some 2 m below surface (below frost level if temperature goes below zero degrees Celsius).

This is a relatively new "green" method of energy production in North America.

Thank you for your recommendation, Mr. Issigonis. Your recommendation is very important to me.

Alternate sources of energy are necessary because: The mainstream fossil fuels like coal and petroleum are non renewable so their reserves are ending fast. ... The CO2 obtained from burning fossil fuels is leading to greenhouse effect leading to global warming and some other negative effects.

• Wave Energy.
• Biofuels. ...
• Natural Gas. ...
• Geothermal Power. ...
• Wind Energy. ...
• Biomass Energy. ...
• Tidal Energy. ...
• Hydrogen Gas. Unlike other forms of natural gas, hydrogen is a completely clean burning fuel

I think the global warming can generate energy for use.

Renewable energy the best for future

The world domination of "green" politics can not only solve the most serious of the existing problems of mankind, but also create new, no less unpleasant problems. If all the inhabitants of the earth EN masse switch to electric cars, there will be fierce competition for lithium for batteries — and this is another exhausted and geographically limited resource. Due to the fact that some alternative energy sources will require huge amounts of water, some regions of the world are waiting for drought and conflicts. The more environmentally friendly nuclear power plants in the world, the greater the risk that terrorists will be able to access radioactive waste, and the higher the number of countries developing nuclear weapons.

Dear Colleagues and Friends from RG,

In my opinion solar energy is a great hope for the development of environmentally friendly energy now and in the future. Solar energy is a great hope for the development of pro-ecological energy in the future and is an important factor in implementing the principles of sustainable pro-ecological development in economic processes. Technological development in the field of construction technology of renewable energy power plant, subsequent, more and more perfect photovoltaic panels, accumulators accumulating generated electricity means that in an increasing number of countries, due to e.g. geographical location and sunlight, renewable energy sources based on solar energy, etc. can be developed Technological development contributes to increasing the range of areas, zones, latitudes that are suitable for the development of renewable energy sources. Due to the successive progress in the field of renewable energy technology, the number of countries that are geographically and climatically less able to develop the most environmentally neutral renewable energy sources, i.e. the development of e.g. solar energy (due to geographical location far from the equator), etc. is decreasing. In many countries and globally, the consumption of electricity is expected to increase in subsequent years. The resources of non-renewable energy sources, i.e. contained in the earth's crust, minerals consumed in classical energy (hard coal, lignite, oil, natural gas) are gradually shrinking. However, the most serious problem is the ongoing global warming process. The main source of acceleration of this process in recent years is the greenhouse gas emissions generated by the development of civilization, which have been growing since the first industrial revolution, i.e. since the 19th century. Many scientific data from climatologists' studies indicate that the global warming process has entered a strong upward trend and perhaps humanity has little influence on the change in the pace of this process. However, regardless of this, we should do everything we can regarding the implementation of the principles of sustainable ecological growth, including the necessary ecological reforms, primarily in the energy sector by developing renewable energy sources, electromobility, development of organic farming, improving waste segregation techniques, recycling, etc. These reforms ecological ones implemented in accordance with the green economy philosophy are necessary to at least partially slow down the global warming process. We owe it to next generations, we owe it to our children and grandchildren. One of the key elements and goals of the green economy philosophy, i.e. primarily the implementation of pro-ecological reforms consisting in the implementation of the principles of sustainable pro-ecological economic development, is nature protection, protection of natural biological ecosystems, protection of terrestrial biodiversity and its preservation for future generations. In view of the above, one of the important factors in implementing the principles of sustainable pro-ecological economic development is the reform of the energy sector as soon as possible in order to switch the energy sector from classic energy sources based on the combustion of minerals to the development of renewable energy sources, including primarily the development of solar energy. To sum up, solar energy is a great hope for the development of pro-ecological energy in the future and is an important factor in the implementation of the principles of sustainable pro-ecological development in economic processes.

Thank you very much.

Best wishes.

@ Dariusz Prokopowicz

As well known, every energy generation technology, from fossil fuels to nuclear not ignoring our maravillous sun, has demonstrated its own key benefits, each of these having clearly enthousiastic activists. However, none is being zero-environmental impact.

Then, is not it our responsibilty, as scientists invoved in energy AND environment issues, to permanently assess such benefits and costs to policy-makers and large public ?

Being serious concerned myself, like all of you, I continue to support first, as my own key priority, those Energy Efficient Techologies that aim to provide the best energy services through cheapest technologies altogether from both money cost and environment impact (browse i.e. "Rosenfeld Effect")

Best Regards

Jacques

Recently, I found an interesting start-up: https://energyvault.com/

How much wind was in Europe's electricity yesterday?

https://windeurope.org/about-wind/daily-wind/banners/share-of-wind.gif?date=2020-03-15&time=1631&_nc_hash=AQCHrrgd8NVFtKCR

We should adopt renewable energy. Fossil fuels don't last forever. Renewable energy benefits a clean environment and more sustainable.

I think that the process of real discussions has begun and the scientific work of the participants in this discussion will make progress in alternative energy.

In my opinion, renewable energy has a great future ahead. Therefore, pro-ecological technologies should be developed to improve the energy transformation process through the development of renewable energy sources.

Have a nice day. Regards.

Dariusz Prokopowicz

I agree with Darius Prokopowicz aiming at development of renewable energy technologies keeping utmost importance on ecological balancing. Without leaving some form of impact on environment, no energy transformation is possible

Renewable energies only look good if you do not know how much energy the world uses in a year. Renewable energies are much too small and do not have the necessary flexibility.

The only energy available on the scale to replace fossil fuels is nuclear fission energy and it cannot replace all fossil fuels. In the future we might make liquid fuels from hydrogen and carbon for such applications as aircraft fuel.

See: Nuclear Fission Fuel is Inexhaustible by Lightfoot et al.

Alternative Energy refers to energy sources other than fossil fuels.  This includes all renewable sources and nuclear.  Nuclear is not classified as a renewable energy source.  A renewable energy source is produced from sources that do not deplete or can be replenished within a human’s lifetime. Nuclear is produced from mined elements like uranium and thorium which cannot be replenished.

Here is a paper that was published in 2006: "Nuclear fission fuel is inexhaustible" by Lightfoot, Manheimer, Meneley, Pendergast and Stanford. There is uranium for tens of thousands of years and after that there is thorium.

There are more than 4 billion tonnes of uranium in the oceans and it can be recovered.

Therefore, for various reasons mentioned above, not only in the future but also now the scale of development of renewable energy sources should grow.

Regards,

Dariusz Prokopowicz

Renewable energy sources such as wind, solar, tidal, biomass and hydro are much too small and inflexible to provide the World's energy needs. They only look good if the scale of energy required is ignored. The world uses around 600 exajoules of all sources of energy annually and fossil fuels are 80% of this. The renewable energies account for about 10%, of which hydro is about 70%.

When you consider scale, renewable energies are small and will remain so for good scientific reasons. Ignoring scale is the mistake proponents of renewable energies make and continually make. They never appear to learn.

Modern and alternative energy is better in terms of economy and reducing environmental pollution compared to fossil fuels, oil and other sources that emit polluting gases to the air and water environment

However, it remains weak and does not meet the required power requirements

For those who forget their history! The reality is that in the 1920s and 1930s jobs were more important than pollution. As a result the vegetation along some rivers in BC was decimated by fumes from the smelter at Trail. As people became wealthier, jobs were not as important and the pollution was stopped.

We cannot live without fossil fuels today. With people being wealthier than ever before in history, the demand to reduce pollution is increasing.

To think the solution is to eliminate the fossil fuels that are 80% of our current fuel supply is to believe in fairy tales. I realize that fairy tales are popular because they make things look easy. Realistically, replacing fossil fuels is not simple or easy—it is extremely difficult and there are no solutions in sight other than partial replacement by nuclear fission. And it appears there is nothing in the future.

It is the pollution that must be stopped not the use of oil.

The development of renewable energy sources is a key element of both diversification of energy sources and reduction of environmental pollution, as well as the possibility of implementing the principles of sustainable development based on the concept of green economy and circular economy. Therefore, the development of renewable energy sources replacing the classic energy based on the burning of minerals is also one of the most important elements of counteracting adverse climate change, primarily counteracting the global warming process which has been increasing faster in recent years.

Alternative energy sources (Renewable Energy) is the future of enegy production. The problem we have now on pollution is already in research and ways of handling them would come up soon in time.

How much wind was in Europe's electricity yesterday?

Solar and wind power are already a reality, with viable costs and less pollution than thermal power. In Brazil, ethanol is made from sugar cane, which is mixed with the gasoline of all automobiles, forming a clean and renewable energy.

Alternative renewable sources of energy are booming and promising.

I agree with Roberto

Powering the World with renewable is a fairy tale dream. It is an emotional response to a difficult problem by uninformed people.

Get your facts straight!! Ethanol is not made from sugar cane stalks, i.e., bagasse. Sugar extracted from sugar cane stalks is dissolved in water to which yeast is added. The mixture ferments to ethanol and carbon dioxide. The ethanol is diluted when formed and must be distilled to recover it. The energy required is high grade energy and is about 90% of the energy in the ethanol. Ethanol has less fuel value than gasoline, Thus, adding ethanol to gasoline reduces the fuel efficiency per kilometer.

If you insist on using food for fuel, someone will not eat. The use of corn to make ethanol has increased the price of corn to those who rely on it for food.

Powering the World with renewable energy s a fairy tale dream. It is an emotional response to a difficult problem by uninformed people.

Read Donald McKay’s book “Sustainable energy without the hot air” and become educated about renewable energies.

It's an inevitable reality, more sustainable and with less polution.

The alternative energy is part of process of sustainable development that must define our future.
