Not really. 1/3 of your electricity production today is coal, while your nuclear dropped from 25% in the 90s to zero today. If you kept your nuclear - rather than shutting down your reactors well before the end of their life - you would be burning far less coal
Most European countries including Germany use less electricity now than in the 90s, so the percentage would have risen if you kept the same output of nuclear power
Nuclear peaked at 11% in the 90s and is now zero
