The anti-nuclear sentiment is much older than Fukushima, going back to the 80s and earlier. An official exit was already ratified in the late 90s/early 00s, but then Merkel and the CDU unilaterally decided to stop it due to lobbying from energy producers. It was only picked up again when Fukushima lit a fire under her ass and she caved to public pressure.

Nuclear and renewables do not synergize. Wasting money on nuclear energy is a dead-end. The ship has sailed long ago.

No. Sourcing nuclear fuels isn't clean and building NPPs is a behemoth undertaking. By the time you've approved and built a single plant (10+ years) you could've covered half the country in wind-turbines and hydro-plants, all of which are built and operated independently.
