When I bought this place it was a wreck. I had to put in new systems, so I made them energy efficient. While I still need to insulate better, I'm doing pretty good.
The attached chart shows my annual costs for energy. I have an on-demand hot water system, so waste no energy. I heat primarially with wood, unless I'm away then I have kerosene back up heat. My electricity averages about $21 per month. When possible I cook on the woodstove so I don't have to use the gas stove in the kitchen.
