It was just so obviously stupid. I don't have time to wade through German government websites finding the trail.
Modern civilization, like in Germany, requires a certain per capita level of energy resources. If you increase the cost of energy without a matching increase in economic resources you lose functionality in your infrastructure.
Germany willfully chose to cut domestic energy production and increase its own costs. Now its core manufacturing is crumbling. BASF, for example, is relocating to China[0]. They claim they're using 100% renewable energy there, but such claims are easy to make in China and hard to verify.
The Western sustainable energy policy is like watching a man hit himself repeatedly in the head with a hammer and then wonder why he has a headache.
