Our new house in Oregon will be all electric. Heating and cooling will be with mini splits. With the electric and gas rates there, which are pretty typical for most of the US, it's far cheaper to heat with mini splits. But even more important, I've stayed in places with mini splits and they're super comfortable. With the central air/heat in our CA home the blower and furnace or A/C goes on, then goes off, then goes on. So the temp fluctuates. The mini splits just ramp up and down as needed to keep the temp steady.
I'm looking forward to not having propane. No worrying about getting a delivery when we're nearly out. No tank of explosive fuel to spew flames or explode in a fire. There is some footage out there from I think the Camp fire in Paradise that shows tanks with big jets of flame spewing from their vents, and in the distance, sounds of tanks exploding.
The utility there has a mix of sources with a lot of renewable and they're adding more all the time. We'll probably put in solar as well. If it's big enough it will offset all our use.
