To be honest, we could save a lot more if we get off of our butts. We cut our own wood from the forest, which is $15 for the permit (to cut a cord), then chainsaw maintenance, oil and gas, and gas money for the truck to go back and forth. We have a large furnace downstairs, but we're thinking about replacing it. It takes a lot of energy to run the blower and all of that hoop-lah. We're talking about taking it out, removing the hosing and just putting another regular wood stove down there. That would eliminate any need for electricity to run it. I don't know what they said they paid for the furnace (might have been free), the old wood "stove" (was more like a fireplace!) came with the house, and the new woodstove (for upstairs) was free from my mother. We're also cursed with an uninsulated house. We have a lot of work to do here, lol.
