There are good reasons to phase out nuclear (which was supported by all major political parties, a decision of the vast majority not only the green party).
E.g. usually, the proponents ignore the risks. The day before Fukushima they would have said, Tchernobyl cannot happen here. The next castastrophe comes always from a direction nobody anticipated. In the 2010s CDU in Germany delayed modernizing the german power grid by a huge amount which the greens could not catch up entirely during their recent term in the government (as part of a difficult coalition). This power grid is now a bottleneck to install and use intelligently more solar, wind and batteries (new solar already compensated for the phase out of the last 3 nuclear power plants in the early 2020s). CDU is again in power and again doing counterproductive measures to slow down modernization of the energy system. There is no need for nuclear but for faster modernization of the grid and for more renewable energy production and storage capacities.
