Part of the reason Germany is still stuck on fossil fuels was the ultimatums of the environmentalists that killed their nuclear power. IMO if they really care about the environment they need to chill out so people can work out how to transition. Hard rules like this will first result in desperation which causes people to make sub-optimal choices like you're seeing now and eventually economic collapse which will absolutely destroy the environment (think of all the messes the USSR made when it fell apart.) Whatever regime replaces the one that causes this probably will care a lot less about the environment too.
