Well, my gas bill is $100+ in the summer just from hot water, cooking, and running the dryer, so $200 isn't doable in the cold.
I live in a big old house with lousy or no insulation and an antiquated heating system. I do not have the $25-30K or so it would cost to insulate and get a better furnace. Not to mention, even though I replaced the windows 12 years ago, I did not get the best replacement windows. I also have a wife who insists that the heat be on. I am fine bundling up. Plus, I have 100 pounds of blubber to keep me warm. Anyway, while NYC is pretty hit or miss in terms of snowfall (I think we got very little last winter, a decent amount a year or two before), January and February are consistently cold enough (not -20 or anything, sure) that I have to keep the heat on. Unfortunately.
