The problem is it’s also the most currently affected. Mostly due to historic forestry mismanagement (which they’ve corrected but it takes time to make an impact) and the maliciously incompetent behavior of PG&E.
Most of the East Coast is going to be a mess. Same with states near the Gulf. Texas can’t even function now in climate fluctuations without having its grid collapse.
California has its issues, but they’re largely caused over water rights being improperly managed due to unrestrained agricultural usage. Fix that and they have much a ton fewer issues.
