If you move somewhere where there are tornadoes, hurricanes, floods or blizzards, which is much of the U.S., you also risk losing electrical power, and often unpredictably, and for days at a time.
I agree with HCH, if you have necessary medical equipment that runs on electrical power, you should consider a backup solar and battery system, or even a small generator, if you can afford it. Many here in Los Angeles have those systems installed in the event of earthquake or any other kind of disaster. I have a small gas powered generator to keep the fridge and freezer running.
I’m not sure if a city like Los Angeles would be affected by those PG&E fire-prevention blackouts, since we’re with the L.A. Dept. of Water and Power, and I don’t live in an area prone to wildfires.
