Renewables really aren't that cheap unless you view them entirely in isolation. Sun doesn't shine all night and wind doesn't blow continuously, it needs to be viewed with storage to represent a complete picture. Rooftop solar is more expensive than nuclear due to the zero economies of scale, residential storage is staggeringly expensive, and utility scale solar + storage only became less expensive than nuclear power a couple of years ago.

Solar and wind both have significant sovereignty issues. The entire solar supply chain is in China where they're heavily subsidized so the PRC can corner the market -- and substantially all the rare earths in wind turbines come from China. Generally recycling costs aren't considered and at least in the west there's no plan to recycle at least the fiberglass in turbine blades, leaving them to be buried.

I'm all for renewables but the way they're positioned is unrealistic.

Nuclear is only expensive because of the way it's built in the US, relying on the few locations made available (if any) to build basically fully customized installations. If we copy-pasted reactors onto sites that suit them it would be very competitive, don't take my word for it. Jigar Shah who headed the DOE loans program said the exact same thing during his term.

If we're being pedantic, nuclear is renewable too thanks to seawater extraction. There's a practically unlimited amount of uranium in the ocean and the rock underneath it.
