Earlier quoted context omitted.
The problem is that now there is less money for developing a grid of green energies and we need it for yesterday. Because nuclear will take a chunk of the grants, as is much more expensive to build and much more time consuming. So green energies, delayed in the last decades for political reasons, will need to wait, again. And this delay could turn to be a very bad decision in a few years.
That is just fear mongering. We have no evidence of nuclear being built in-place of cheaper renewables. Until we do it's just FUD.
More research is probably needed, but I wouldn't say we have "no evidence".
