A truck stuffed to the gills with batteries would hold maybe 4 MW-hours of energy. You'd need a lot of trucks, except most of the time you wouldn't need any of them and they'd just sit around. Sounds expensive?

The power density is low, but presumably you're not running every electricity using device while you're hooked up to emergency power. This idea may be worse than just keeping a grid around, but my point was more along the lines that we are not tied to needing a grid itself anymore if we get power generation at every home/business. We still need some sort of backup power system, but it is possible that it takes a different form
