We lost power for a few days this spring. Luckily the weather was nice so we didn't need heat to keep the pipes thawed. No AC when it is less than 90 degrees is no big deal. Hotter, it gets uncomfortable. All we did was:
1. Did not open fridge or freezers.
2. Put out candles at night.
3. Read books at night.
4. Went to bed early.
Guess what happended. Power came back on, the food was ok, and we were able to catch up on our shows. It was actually quite pleasant.
I have lost power in winter and that sucks because you have to worry about frozen pipes bursting. That's about the worst I can imagine. Now that I have a CPAP I would still be okay because I have a battery back up for it and solar charging for when we camp.
