It isn't a fair comparison as Germany has terrible geography in comparison to the US for energy generation, and certain energy sources like hydropower are very efficient, but not possible to replicate given the environmental impact.

Hell, even solar generation in Germany isn't anywhere as good as the US, where it can build solar parks in the south, meanwhile most of Germany has what, 6 hours of daylight during winter?

To me, it's absurd that the US has literally the best geography of any country in the world and yet isn't coal-free.

It has even a river that divides the country. It's almost as if it was hand-drawn by god. With mountainy regions, hot and cold areas, deserts and tropical areas, America you have no excuse and can do better.
