It will be interesting in electricity starved California as well. I don't know the percentages, but I believe I never once lived in or visited anyplace in CA that wasn't gas heated. I was actually kind of shocked to see so much electric (via heat pump) heating here in Potatoho.
I remember when CA was experiencing blackouts and brownouts under Gov. Gray Davis. Someone in California proposed - seriously - that the Federal government
require Nevada to send California
all the extra electricity they needed. If Nevada consequently came up short, Idaho, Utah, and Arizona would be required to send them enough power to replace what they were going to send to California. Colorado and New Mexico in turn would have to make up any resulting shortages in Idaho, Utah, and Arizona. And so forth and so on - their proposal involved California calling the shots on electrical distribution all the way East as far as Indiana.
This proposal went nowhere, but I I'm positive that it's still in someone's desk, ready to be dusted off and resubmitted as soon as their all-electric mandates start having the unintended - but entirely foreseeable - negative consequences.
