The problem with solar is that the sun doesn't shine overnight. The good thing with that is that we use much less power overnight than we do during the day.

If you're relying a lot on solar, you need to build a big-ass battery that you charge during the day and use at night.

Alternatively, you build a nuclear or gas plant sized to overnight usage and run them 24/7. Then, you build way smaller batteries to handle dispatchability and smoothing demand over the course of a day. Nuclear is good for baseline power, and doesn't come with the environmental costs of a gas plant. It has a niche.

Big if true. Winds tend to be stronger at night though.

Or pumped hydro, compressed gas, molten salt, green hydrogen, etc.

Base load. See here: https://cleantechnica.com/2022/06/28/we-dont-need-base-load-power/
