p.s. I'd also point out that there is an imperfect tech solution in place....nuclear energy that can at least supplement the renewables. But Germany is taking a step backwards and shutting down its reactors, which on top of everything else makes them more dependent on the Russians. Government by feeling instead of facts. If part of your solution isn't nuclear, then again you aren't acting like it's an emergency. Yeah I know the downsides, but I'm not the one claiming "emergency".
New reactor designs in development avoid the need for a pressure vessel and thus most of the risk of off-site discharge of radioactive materials such as what happened at Chernobyl and Fukushima, or even the trivial emissions from Three Mile Island. Perhaps demonstrating safer operation will change the Germans' minds.
