If the goal is decarbonation, using wind+solar is alright (renewables are a bigger part of the mix in Germany) but burning gas and lignite when there's no sun or wind is not.

In Germany the problem is coal (lignite): it remains a huge social and political 'asset'. Many jobs, low-priced electricity, no dependency towards fuel shipped by a foreign nation...

France switched to nuclear because at the time it didn't have any fossil fuel ( https://sites.google.com/view/electricitedefrance/messmer-pl... ), while Germany (especially the then-RDA part of it, Soviet-controlled) had huge reserves.

Phasing-out coal is therefore difficult for Germany, however it does so and the acceleration after Fukushima (2011) and during its nuclear phase-out is impressive: https://ourworldindata.org/grapher/share-electricity-coal?ta...
