Indeed. Frankly, I was all about buying energy efficient stuff when I moved in here anyways. Had an apartment once with the $300 gas bills, didn't want to do that again.

Already have an Energy Star fridge, and Energy Star washer and dryer. Didn't go top of the line, but I got decent stuff, and the energy efficiencies are going to pay off long term.
My new furnace will be 95% AFUE, and I'm most likely going to get a woodburning fireplace insert too. I love having a fireplace, but it's not built very well, and doesn't push much heat into the house. The insert lets me burn wood, but has blowers to move that heat out into the rest of the living space. I considered a pellet insert, but the insert would have been almost as expensive as the furnace once it was all said and done. Might put one in the basement once I refinish that though.
Man...I feel like such a hippie.... :p
EDIT : Tankless water heater was on my list. Would have had it in by now if it wasn't for the furnace going.
