I have a very high efficiency propane FHA furnace, a cast iron woodstove (I burn 2 cords/ yr) and a propane cookstove that has 2 continuous pilot lights that keep the kitchen toasty with no electricity consumed. The furnace rarely runs if I have a fire going in the woodstove, so most of my generator load is just lighting, refrigerators and the odd well pump cycle. 2 cords of firewood and 600 gallons of propane keep the house warm for a year.
