On the grid issues: it seems like battery storage is either massive or individual. What doesn't seem to be happening is battery storage at the substation level. It would take planning but substation batteries could run low during the night and be re-charged by solar panels during the day.

In the event of a major power line being damaged, there would still be power for some amount of time coming from the substations.

Somebody I talked with last night was vehement about how irresponsible moving to EVs is, that the grid simply isn't up to it in her opinion. It's hard to get new power lines approved but distributing energy storage seems like it would help.
