I don't think that anyone thinks EV's service every need yet. I don't think I would have only an EV if I was in a evacuation area for hurricanes.
A friend who lives locally has an EV that he charges with a solar setup and it functions well enough to do so all year round. It is, of course, significantly more efficient in the summer. He was very happy with his setup during last year's gas shortage.
I have seriously been considering an EV that had enough range to get my to work and back. The car I currently do that in will probably not make it much longer. It would never be my only option, but now I am wondering how much propane it would take for my generator to charge it if necessary.
