Mine is 2.27. I am wondering if that has to do with having a large (just under 3,000 sq. ft.) 4 bedroom home? I have to think the calculator is 'assuming' I heat the entire thing in the winter, which I don't. I close off rooms unless kids/guests are coming to stay. Yeah, I am nice enough to allow them heat, especially the grandkids.
I say this because my year round natural gas bill/ budget plan is only $92 and our winters are brutally cold here. I also recycle pretty much everything, could do a lot better on that, and I compost a lot through the year too - great for my garden and the neighbors.
Thanks for putting that up, walksalone! I think it's cool and useful for us to be able to see how much we take up. I saw your results @ 0.00 too and wondered how you were still alive.......
