Later this week I'd expect multiple areas in the Santa Cruz Mountains to lose power (from the coming storm). It's very common, happens multiple times per year (fires, winds, rains can all cause it). Sometimes it's just a day, sometimes many more.
Unless I someday get to live somewhere with a very substantial solar system, I won't ever be with only an electric car. Grid-delivered electricity isn't reliable enough to bet on.
And consider storms like hurricanes Irma and Maria which left many areas of the Caribbean without power for multiple months.
In the Bay Area, it's regularly an occurrence where people in the Santa Cruz Mountains will not have power for 2 days to a week. With little to no notice too.
You come home with a low battery to refill it at home, you might not be able to get very far. Hopefully you just drive with 50+ miles ready all the time.
