Some years ago a friend lived in a part of Memphis where they had an extended power outage. Something like 10 days. It wasn't cold enough for the pipes to freeze, but they had an all-electric apartment and had no light or way to cook anything.
They drove 150 miles to here, borrowed our Coleman stove, Coleman lantern, and a Mr. Heater propane heater head, stopped at a K-Mart on the way out for fuel, and were able to live a bit better until the power came back on.
We have gas heat here - "space heaters" that the insurance company hates, but they don't require any electricity. Neither does our old pilot-light type water heater. We've been in the dark a few times, but at least we were warm...
