Germany's wind and solar is only possible because neighbouring countries compensate for when there's no wind and sun; which happen a lot of the time. On top of that wind and solar production must be bought first on the EU market, effectively ruining CO2-free capital that was there beforehand (read: nuclear).

So these charts that you show only demonstrate that Germany was first to jump on wind and solar production. Great for them, but now wind and solar in neighbouring countries are much less profitable when they'd be less correlated to Germany's huge wind and solar capacity.

Perfect play in a game-theoretic setting, but damaging to the neighbours and the actual goal of CO2 reduction.
