Well, the German Greens (along with NGOs like Greenpeace) have always campaigned against nuclear in a way that very effectively shaped public opinion to allow Merkel to use the Fukushima scare as an opportunity to shut down nuclear power.

Note that Germany's newest nuclear power plants were built in 1982, before the Chernobyl incident and before the merger of the West German Greens with the East German progressive movement (which made the party more politically relevant). This resulted in lifetimes of existing nuclear plants continuously being extended, which in terms of safety was much worse than building new ones.

There are six plants currently still operating, half of which are scheduled to be shut down by the end of this year, the other half scheduled to be shut down by the end of next year.

Ironically, the nuclear scares have not resulted in a massive expansion of renewables but in a strengthening of fossil fuels and especially coal (which is heavily subsidized and has even led to land being expropriated "in the common interest" to allow energy companies to harvest lignite).

As of 2018 Germany has vague goals about abolishing coal power by 2038 due to public pressure but in the most optimistic scenarios this doesn't involve shutting down any coal plants before 2035. That this is being discussed by (conservative and centrist) government officials at all is only the result of the Fridays For Future protests and related spillover movements (XR and more specifically "Ende Gelände", a series of protests directly targeting the surface mining sites).
