For us, not having power is rare and normally short duration of a few hours.
I'm also used to "camping" without power, running water, just like folks used to live in the country in 1920 (means using an outhouse, and washing clothes with a scrub-board in a galvanized tub).
We don't watch tv or use a computer when "camping", just like in 1920.
We have LED flashlights and since they use so few batteries, we could go months for the lights.
We also have a BBQ on a propane tank, so we can cook and boil water outside and a 20 lb tank will last 2 wks (normally lasts 4 wks).
We have a bunch of canned food, and 10lbs of rice to eat after gorging ourselves on the freezer contents during the first 3-4 days of a power outage.
So I feel we are fine if it happened.
