"Coal is the second-largest source of electricity in Germany. As of 2020, around 24% of the electricity in the country is generated from coal. This was down from 2013, when coal made up about 45% of Germany's electricity production (19% from hard coal and 26% from lignite)." - Wikipedia ( https://en.wikipedia.org/wiki/Energy_in_Germany#:~:text=Coal...). )
But sadly it went slightly up from 24% to 24,5% in 2020 (don't have the source at hand right now for this second statistic).
The rest is Gas, which has become very expensive this winter. And Coal.
We would need to invest into power-to-gas like crazy if we wanted any shot of providing a base load.
