Not directly, but a key point of his thesis is that solar by itself (with batteries) can provide 85% more power than we currently use by only using the land that currently grows corn for biofuel on. He mentions wind as well.

Nuclear has its own lies spread about it that are completely independent of what renewables get and it has its own caveats, so, it does kind of make sense to not really bring it up since that could warrant its own video. Illinois has nuclear power, so, I can't imagine it was an accidental oversight.

I don't think so, but then again it's a long and dense video and I might have missed something
