I mean, you can get light when it's dark, and possibly run a refrigerator from a solar installation, but otherwise what would you use the electricity for? Not for heating, not for transportation (not enough of it), your cell phones and other computer devices won't be of much use without the network anyway. Perhaps if you have portable radios you could charge them, but otherwise — what?
My conclusion was that we've become alarmingly dependent on infrastructure. I decided to get some maps, old-style paper books, and started considering getting radios and tiny solar panels to re-charge them.
I guess reasoning along those lines, you're looking for literal generators that can be adapted to whatever fuel you have available.
