Expansion of wind power
Community self-sufficiency still blocked
Electricity customers without their own homes should also have access to cheap green electricity from the roof, according to the EU Renewable Energy Directive. The federal government claims to have implemented the directive. The Bündnis Bürgerenergie contradicts and announces legal steps.
The new version of the European Union’s Renewable Energy Directive (RED II) has been in effect since December 2018. Among other things, the directive provides for facilitation of the joint use of locally generated solar energy.
That would significantly improve the profitability of tenant electricity. But other solar systems could also be larger because the surplus electricity can be sold in the neighborhood instead of on the general electricity market.
That is why cooperatives, among others, who want to promote the energy transition with urban roof solar systems, have been waiting since 2018 for the directive to be incorporated into German law. This should have happened by the end of June 2021. But there is ongoing controversy about the implementation ...

Wikipedia
solar energy
Solar energy is the energy of solar radiation that can be used technically in the form of electrical current, heat or chemical energy. Solar radiation is the electromagnetic radiation that arises on the solar surface as black body radiation due to its temperature of approx. 5500 ° C, which is ultimately due to nuclear fusion processes in the sun's interior (hydrogen burning).
Solar energy can be used both directly (e.g. with photovoltaic systems or solar collectors) and indirectly (e.g. by means of hydropower plants, wind power plants and in the form of biomass). The use of solar energy is an example of modern backstop technology.
Intensity
The solar radiation hitting the earth has been almost constant since it was measured. There is also no evidence of significant fluctuations in historical time. The average intensity of solar radiation at the boundary of the earth's atmosphere is around 1367 W / m². This value is also known as the solar constant. Part of the radiated energy is scattered and reflected by the atmosphere from solid (e.g. ice crystals, dust) or liquid suspended particles as well as from the gaseous components. Another part is absorbed by the atmosphere and already there converted into heat. The rest goes through the atmosphere and reaches the surface of the earth. There it is partly reflected and partly absorbed and converted into heat ...

Increasing production
The share of solar energy in gross electricity generation in Germany, which rose from 5,9% in 2016 to 7,0% in 2017, was 2018% in 7,1.
In May 2012, the International Economic Forum for Renewable Energies (IWR) announced that Germany generates as much solar energy as 20 nuclear power plants on sunny days.
In autumn 2013, solar power was 10,9 ct per kilowatt hour in Central Europe for the first time cheaper than electricity from new nuclear power plants. According to "Frankfurter Rundschau", if you take the electricity price of the new nuclear building project - Evolutionary Power Reactor EPR - Hinkley Point in the UK, as the benchmark for public pricing for the first time, solar power was cheaper than nuclear power again in 2014.
According to calculations by the Fraunhofer Institute for Solar Energy Systems ISE, solar energy systems increased their energy production in the first half of 2014 by 28% compared to the same period of the previous year ...
