You can see right on the screenshot 57% renewables with wind being the biggest source of electricity. That means by adding 75% more renewables Germany would be able to support itself. The reason Germany sucks so badly at this is that it uses coal instead of gas. Gas power plants have a third of the emissions of a coal power plant per kWh. In terms of share of low carbon electricity Germany is doing alright and is building a lot recently. Since Germany has coal power plants instead of gas ones for the most part, it also means Germany is replacing those coal power plants. So this should go down quickly.

Also battery storage is growing extremly quickly in Germany and the rest of the plan is hydrogen in gas power plants for dunkelflaute. However at current rate Germany should have an electricity system as clean as France within a decade. The built up numbers for renewables are strong enough for that and we are talking about nearly 60% renewable electricity production last year already.

France has had a huge nuclear crisis in the last couple years with a rather long times half of the power plants being down due to technical issues. The UK is currently having 6 out of 9 npps down.
