New research by the Fraunhofer Institute for Solar Energy Systems reveals that solar photovoltaics — converting solar energy into electricity — produce cheaper electricity than coal or gas, even when combined with batteries. The Fraunhofer Institute has been collecting data on the costs of different energy sources, like wind, nuclear, and coal, since 2010. While … Continue reading New study reveals that photovoltaic and wind power is now cheaper than coal and gas power plants
