They childishly think solar and wind.
The irony is that the German people have traditionally had the best technical minds in the world. I wonder if there are any technology giants in Germany screaming the warning “This will NOT work!!”
IMO, solar is a lost cause in Germany, wind a possibility in areas on the Baltic Sea (but you better winterize them half the year), tidal wave generation a small possibility.
Nuclear is the smart move here, but they passed on that, too bad, so sad.
