Hence solar, which generates until sunset, paired with ~4 hours of storage, which carries the grid through peak evening load until most folks are off to bed and grid load declines rapidly.
And then it's a rainy day and everybody stays home from work because there's no power? Or we spin up a bunch of dirty natural gas?
This also doesn't address the seasonal changes in supply. We're realistically talking about creating energy infrastructure (and then maintaining it) that ulaverages maybe 20% capacity.
I just feel like solar proponents like to completely ignore the very real unsolved issues because solar+batteries is tidy if you don't think too much about it.
Natural gas fired peaker plants will continue to be a crucial part of our electrical system indefinitely. They allow generation to be rapidly spun up and down to stabilize the grid; other generation sources can't react as quickly, or sometimes can't react at all. And natural gas isn't very dirty.
