Ok, but what do you do when you’re short of power at night? Keep in mind to turn on conventional power stations it’s expensive & time consuming. Once they startup they need to stay on for a long while to be efficient & cheap.
The real solution is to store excess power in batteries. Lithium ion is too expensive to scale, Sodium ion batteries are economically & capacity viable AFAIK.
I’ve read that gravity batteries and sand batteries are ecologically sound options that work on the scale needed to support large sections of electrical grid.

Thats just not what this post is about. Obviously storing is the way but until then yiu just gotta turn em off
