As can be noted, I did not mention renewable energy. I talk about phasing out fossil fuel, becoming carbon neutral, i.e. including nuclear power. Take Sweden and Norway as examples, no gas is being burned there to generate electricity or heating. The public opinion on nuclear has shifted thoug, the public has realized - as you point out - that nuclear is needed as the base power generation, as well as the adjustable component of the total power generation. But Norway has zero nuclear, and manages to supply their power needs (including the world's biggest fleet of electric vehicles per capita) from hydro alone. Sweden has roughly 45% hydo and 45% nuclear, and solar and wind makes up for the rest. So renewable, short term, is not realistic, no. Carbon / fossil free is however.
