Wintertime wind and solar energy "between 0 and 2 or 3 percent – that is de facto zero," says German power distribution professor.
Berlin's power supply severely strained
Germany now finds itself in the dead of winter. Much of the country has seen considerable snowfall, meaning solar panels are often covered by snow and thus rendered useless. Even without snow cover, the weeks-long overcast sky prevents any noteworthy solar power generation.
Moreover, this winter there have been many long windless periods, and so Germany's approx. 30,000 wind turbines have been largely out of operation. In a world 100% reliant on green energies, this would mean near 100% darkness at home.
