No, but the externalities of fossil fuels, the worst energy sources, are very significant. Yet these get subsidized in many countries and Germany is even moving to coal. I'm comparison between nuclear and fossil it definitely matters.
Last month, Germany also closed down the last nuclear power plant [2]

Nuclear is the most expensive way you can think of to generate power, but the most expensive power plant unfortunately dictates the price on the energy market in the EU ("Merit-Order") [1]
The merit order article you have linked is typical lobbist brainwash as to why your country needs to depend on gas when the sun doesn't shine and the wind doesn't blow.
Starting from 2025, each year, 7,8GW of wind and 22GW solar power will be added into the mix.
For reference, the nuclear plants we just shut down produced 4GW in total.
Germany is exporting excess energy each years to France and other neighbours. 2002 was the last year we had to import energy. [2]
