Germany brought a few coal plants out mothball to prevent the collapse of the French grid when half the French nuclear fleet was off line at the height of the energy crisis.
Which then were promptly mothballed again when the French got their nuclear power under control.
This is not something you can answer clearly, no one can.
I personally would say since renewables (there are many different types of renewable energy sources btw) are so much cheaper and easier to build they are more consistent.
France for example has really shitty nuclear plants that have been falling apart since the 90s - they are not reliable and fixing them is not feasible
Since the nuclear phase out began both coal and nuclear is down replaced by renewables. Fossil gas is stable.

But lets blame the French nuclear power not delivering on Germany. That makes total sense.
