Regardless how you see it, keeping nuclear plants running would have considerably reduced the need for coal and gas, which should be the damn absolute priority.
One actually infuriating thing is, the EU set targets and penalties over installed renewable capacity, not over emissions. So while Germany is generating considerably more emissions that most of western Europe, they were the "good citizen", but France had to pay penalties for not having installed enough renewables.
You can see how much sense it makes at any time:

That's what I call a cynical policy written by people who want to score points but don't give a flying fuck about climate.
