Again… You can and should swap in hot sunny areas specially California. I’m from California originally. You gotta be retarded not to have solar panels now. But over in places where shit freezes like here near Seattle, the entire north, and or maybe also texas, thar doesn’t work. Here in the PNW, we have all electric kitchen, but also a wood burning chimney and a gas burning central heater. If the power is out you get no heating and die…or you keep warm with a chimney fire. Well heat pumps also work using propane or natural gas. There are also gas powered heaters that don’t need electricity.
