Lived without power for many years. Had an outhouse, Even without a well, we would catch water. Luckily where we live there is plenty of rain.
However we always had a wood stove as we didn't trust propane. (I don't even know if propane was availible on the islands then. It is now, but we still don't have it.And we didn't want to buy anything. Put stuff outside in the winter to keep. Put up dried meat. Which always keeps!
Made cheese from our milk which keeps well, and had a cool cellar.
I guess we were kinda backwards.
We made lamp oil out of rendered fat, for light.
I still make soap.
But now we are old and we have power, electricity.
But we loose power during the winter due to big trees and strong winds.
I don't think I could live without a woodstove.
