Some key insights from the article:
Basically, what they did was to look at how much batteries would be needed in a given area to provide constant power supply at least 97% of the time, and the calculate the costs of that solar+battery setup compared to coal and nuclear.
No, but I don't think you're appreciating how difficult it would be to fill that 3%. It's not just about having 3% more power from something. It's having it at the right time. It needs to be on demand. Having something on demand that has to cover all it's costs selling just 3% isn't easy.
It's more resilient to have mixed supply where multiple types of generation take a proportion. Then when one falls short another can scale up a little.
I understand, but other people lose their shit at not having that 3% and basically equate it to being 100% coal. I basically hear:"We're still burning coal, so it was a complete and total failure! B b both sides same."
