When the power goes out, it's almost always in the winter. So we pull out the propane lanterns and let them do double-duty of lighting and heating. If it looks like the juice will be off for a while, I crank up the genset. It's a 4kw Honda commercial unit, and it runs pretty damned quietly, and provides enough power for the fridge, freezer, well pump and septic. We have a 1950's era propane boiler in the basement that feeds a gravity hot eater system, so we can fire that up on about an amp of power. But we mostly heat with wood, and to be honest, I look forward to the power going out in a snow storm. Everything is so quiet. We forget how much background noise comes from electrical stuff. And it's nice to escape it from time to time.
