With photovoltaics, the goals of energy system transformation can be achieved rapidly and in large parts without subsidies — proposals made by the BNE (Association of Energy Market Innovators) that we have been working on.
Biologists have examined 75 solar parks that are up to 10 years old and the results are clear: an increase in biodiversity could be observed in every one of them. https://www.bne-online.de/de/news/detail/studie-photovoltaik-biodiversitaet/
The April 2020 position paper of the Association of Energy Market Innovators (BNE), which we helped to develop, outlines the facts on how 40% of Germany’s total energy consumption can be generated by solar energy. The rapid expansion of subsidy-free open-air solar plants plays a key role in this: https://www.bne-online.de/de/news/detail/klima-mit-1000-gw-sonnenkraft-schuetzen/
