If you say "German plants", I'll point out coal consumption for power generation in Germany has gone down since the decision to phase out nuclear.

Coal consumption would likely have gone down even more with nuclear still being used, but that doesn't support your claim as stated.

In the US, coal generation has been falling for twenty years because it's more expensive than wind and solar. Same reason nuclear is being phased out - grid operators can get power cheaper via wind, solar, import/export, and battery storage.
