Every year new sources of clean energy and technologies are created. New, innovative technologies in the field of renewable energy are being created. The existing technologies of renewable energy sources have been successively improved in the direction of creating more and more economically efficient and energy-saving technological solutions. New patents and innovative technological solutions are being created. New types of materials used in new energy sources devices are being discovered. The main determinant of technological progress in this field should be the process of implementing the most energy-saving technologies on the industrial scale and promoted for industrial implementation and the transport sector should be sources of energy under RES that will emit the least harmful external effects to the planet Earth environment.
In view of the above, the current question is: Will man manage to create and develop on a mass scale in industry and energy innovative technologies of renewable energy sources, through which will stop the greenhouse effect on Earth?

Do anyone have any published journal about renewable energy? or any related to the topic.....
What kind of scientific research dominate in the field of Sustainable pro-ecological development of the global economy?
Probably the future of humanity depends on the next decade. If, over the next few years, renewable energy sources replacing traditional energy based on the burning of minerals are developed on a massive scale, it might be possible for humankind to avoid a climatic catastrophe in the 21st century. The international climate agreement that currently (December 2018) concluded in Katowice in Poland may be a late and insufficient agreement, because most countries do not intend to develop high-budget projects for the construction and development of power plants based on renewable energy sources. In addition, changes in the automotive industry, changes leading to the development of motorization in the direction of electromobility are too slow. The problem is serious because it concerns the future of all humanity in the perspective of the next two to three generations, yet the necessary changes and reforms in the implementation of economic principles of sustainable pro-ecological development are too slow. With the current pace of changes, there may be a shortage of time to implement the necessary pro-ecological undertakings, and then the problem of global warming will become an irreversible process and will constantly accelerate!

There are many possible applications and reasons of utilization of renewable energy.
Please share your opinion where and how renewable energy utilization can be increased?
Also, share your opinion, why renewable energy sources are not accepted significantly?
In many countries, energy based on renewable energy sources is being developed. This development is determined by many economic, ecological and geographical factors. This development results from the need to reduce greenhouse gas emissions and reduce the scale of air pollution by exhaust from mechanical vehicles. The development of energy based on renewable energy sources is indispensable due to the faster global warming process. Therefore, energy based on renewable energy sources should be developed.
Do you agree with me on the above matter?
In the context of the above issues, I am asking you the following question:
What are the main determinants of the development of renewable energy sources?
Please reply
I invite you to the discussion
Thank you very much

Green Electricity refers to Electricity produced from renewable energy sources. It may be Co-generation also.
For the classical power industry to be replaced with renewable energy sources, it is necessary to have the right policy at the state level but also at the supranational level.
The supranational organization of common markets on the example of the European Union is perfect for this issue. In the European Union, successive reforms are being undertaken to motivate the development of modern energy solutions and environmental protection.

What actions should be taken to remove or replace these barriers to the chances of developing renewable energy sources?
Are the main barriers to the development of renewable energy sources the lobbying of enterprises in the energy sector producing electricity and heat based on traditional energy of burning minerals? Is there a lack of financial resources in the majority of countries regarding the financing of high-budget pro-environmental projects from public finance funds? Should there be new, new ecological innovations, new technological solutions in the field of renewable energy sources, electromobility in the automotive field, new generations of batteries, photovoltaic panels, energy storage and transmission stations, hydrogen engines, etc. to produce and use electricity generated on the basis of renewable source of energy has become profitable to become a profitable business? If this process lasts for a long time, there may be a shortage of time to implement the necessary reforms aimed at disseminating in the global economy a model of sustainable pro-ecological development based on the concept of green economy. If this process lasts much longer than by 2030, there may not be enough time to carry out the necessary reforms to reduce greenhouse gas emissions and, consequently, the planet's warming process will accelerate considerably, this process will be irreversible and will continue to accelerate and towards the end of the 21st century century will lead to a global climate disaster that threatens the life of all humanity and most other forms of life on Earth.
In view of the above, the current question is: What are the main barriers to the development of renewable energy sources?

What will it take for the mainstream energy community to look at space based solar power?
The greenest of all green energy sources.
Unlimited safe clean energy 24/7 daily delivered anywhere.
The best hope for displaced aerospace workers (short of world war 3).
The only power source with all these attributes is space based solar power.
Unlimited energy -> solar energy is unlimited
Clean energy -> solar energy is clean. Zero emission. Less waste heat than any other energy source. Minimal environmental impact.
Constant - 24/7 - a solar panel in space is constantly illuminated at full power, no outages due to weather or night time or seasons. No Storage needed.
Delivered anywhere -> the receiving array can be located anywhere on Earth for a fraction of the land area from a conventional solar array. No new power grids needed.
No technical breakthroughs required
What is the catch?
The main problem is the high cost of launching hardware into orbit. With economies of scale these costs will fall rapidly.
Next step: Need to design and build a demonstrator.
Space-based solar power can be developed into a source of clean energy to augment power grids around the World, on the Moon, and anywhere else humans are likely to go.
Space-based solar power already powers our satellites and space stations in orbit around Earth. The trick is to collect enough solar energy on orbit, convert it into a form of power that can be broadcast safely to Earth, and to do so economically.
Figuring out how to do this has been the subject of a number of studies over the past few decades. All of them concluded that space-based solar power as a source of clean energy on the Earth is scientifically feasible, but not technologically or economically viable at the time of those studies, the last occurring in the 1990s. However, the studies also find that space-based solar power is becoming more viable as time progresses because related technologies are making huge strides forward in many cases.
In 2007 we arrived at a general and growing consensus among most of humanity that the global demand for energy will soon exceed our ability to produce it. Complicating matters is environmental contamination brought about by the consumption of our traditional carbon-based fuels. Many believe our consumption of these fuels has irreparably damaged the environment though global warming.
If the technical hurdles associated with space-based solar power can be overcome, it will provide a clean alternative to carbon-based fuels. We do NOT want it to become the one-and-only energy source. We think prudent energy policy should dictate that numerous clean energy sources be developed and should be coupled with appropriate conservation efforts.
There are three basic reasons why going to space is preferred to ground-based solar power:
1. The sun is many time more intense on orbit than on the surface of the Earth. This means there is more energy to be collected. **(See note below)**
2. Unlike ground-based solar power systems which spend roughly half of their time in the darkness of night, space-based systems can be perpetually bathed in sunlight. This is an instant doubling of efficiency.
3. Ground-based systems suffer from weather phenomena such as clouds, precipitation, and dust. These are not worries in space.
Space-based solar power also has three major drawbacks:
1. Despite fifty years of spacefaring experience, getting to space is still hard and expensive. It costs thousands of dollars per pound to lift anything into space from Earth.
2. We have no experience assembling and sustaining objects on orbit of the scale that space-based solar power will require. Some designs suggest systems that are literally several square kilometers in size.
3. Although the efficiencies of collecting power on orbit are many times greater than what can be done on the surface of the Earth, there are significant power losses in converting energy and broadcasting energy both in orbit, during transmission to Earth receivers, and from the receiver into terrestrial power grids. Some calculations suggest space-based solar power can deliver only ten percent of the original collected power.
To make space-based solar power viable, the benefits have to outweigh the costs at a rate that ultimately makes it profitable for a commercial venture to take over such an enterprise.

We are experimenting on a solar absorption air conditioning system which uses LiBr-water solution. We want to get generator temperatures as high as possible. We used evacuated tube collector and we reached up to 72 C from an ambient of 39 C.
In Spain the reguralization is not too equal than other countries. There are some taxes which are not correct. This is slowing the integration of the Renewable Energy Sources in the households. Although Spain has much renewable resources, the government keeps off the development of RES. The auto-consumption is now viable and it needs inversion to improve the technologies and the payback.
There are claims that it is. I would like to learn what you all think.
What the best title to a paper with this abstract:
Abstract
This paper presents the relationship among energy, economy and society. It discusses about the development of societies and energy; energy and structure of societies. It also characterized the environmental impacts from the use of energy sources derived from fossil and renewable resources. Human evolution is closely linked to energy, since the beginning of time man has to know it and seeking it ever more on the environment. He began to enjoy and benefit from its potential fossil and renewable resources. It is discussed the environmental impacts from energy production and utilization, contribution to greenhouse gases and other pollutants emissions. The use of more efficient technologies, along with the application of sustainable energy policies has contributed to a general reduction in the intensity of CO2 emissions by energy production and consumption.
How to improve solar cell efficiency?
Solar thermal water heaters for getting hot water upto 70 degrees celcius are well developed and are efficiency wise pretty good compared to Photovoltaic. If we use a solvent like Di ethyl ether or methanol or suitable refrigerant in solar thermal heater instead of water we can have high pressure system whhich can drive mini turbine to generate electricity which will be more efficient way to produce electricity than photo-voltaic.

What should be the roadmap for sustainable energy ?
Finally I received the results confirming the practical development in 1985 and 1995 theoretical assumptions prove the benefits of the vortex power for high-speed air flow in a high tower. True results are obtained on a mathematical model of finite element analysis program ANSYS CFX and to implement a physical model is still too early to say, but we can already assume that the idea of Co “Adrian Smith & Gordon Gill Architecture” air thermal establish power in the body of a skyscraper "Kingdom Tower" is outstanding achievement in the construction of scientific thought, as I wrote in 1991 in an article “Mamulashvili G. The Energy Alternative Source - Air-Thermal Power Plant - The problems of installation in Georgia Science and Technology, The Journal of Georgian Academy of Sciency, number 6, ISSN 0130-7061 | May 9, 1991”, which I handed to Professor Jorg Schlaich “Schlaich Bergermann und Partner” personally. Unfortunately the owner of the skyscraper "Burji Chalif" and "Kingdom Tower" HRH, Prince Al-Waleed Bin Talal Al-Saud has not yet resumed negotiations on a draft of the first prototype of the cyclone air thermal power for a new skyscraper, which will provide clean energy for a small town.
