If there's no space for nuclear power plants, how are you going to find space for renewables? I can't think of any renewable sources that would take less space than nuclear, especially in Europe since we're further north than the US and that makes solar take up even more space.
Renewable energy production and nuclear power plants have very different space requirements.
> find space for renewables
Germany has more than 30000 wind turbines. For example here in North Germany it's planned to increase the offshore wind energy production by a factor of three in the coming decade. This offshore space is available.
You can only put nuclear power plants next to sufficiently large rivers that can provide cooling. On the other hand you can put solar panels pretty much on every roof and wind turbines in any place with sufficiently low NIMBY density and a bit of wind.
They also have many more space options. A farmer can put one or more wind turbine somewhere on his farm. OTOH having your own nuclear power plant on your farm is usually not an option.
Most roofs still have no solar panels on top in Germany. There's plenty of space for that. You don't have to give up as much space as you'd think for renewables.
Nuclear on the other hand, good luck fighting those lawsuits against the local population. I can't think of any area in Germany that is so underpopulated or desperate for tax revenue, that the local population would be willing to live next to a nuclear plant. There's no "space" for nuclear in Germany in that regard at all.
