After losing power at one point for three days, when it became time to replace our stove, we switched to a gas stove. It still works when the power is off (although you need a lighter to ignite it then) and allows us to cook and keep the house at a livable temperature in the winter when we lose power.
I have lots of camping gear, moved 3 propane lanterns and a propane cook stove into the house, and sanitized and filled my 4 water jugs to have 22 gallons of clean water.
