I'm always interested in other people's utility numbers. I live in the country so we don't have water, sewer, or gas out here. My house is all electric with a heat pump/central air. While I have a small house (1200 sq ft), it's poorly insulated. With two adults keeping the heat at 68 and the AC at 72, our monthly budget billing for our utilities is $114 a month. Some months it's much lower; it peaks around $200 a month in January and February. We live in Virginia so our electricity is controlled by the monopoly that is Dominion Power with no other electric options.
i'll share-
we are in the country as well so no water/sewage. our house is about 2300 sq. feet. we have a mix of electric and propane (fireplace and stove/oven are propane). we keep our thermostat at about 68 year round. we do a balanced payment plan on our electricity-non profit coop- which has not resulted in us ever having a balance due at the end of the year when they run the numbers (maybe a small credit) and it's currently at $255 per month. i budget $1500 per year for propane BUT a chunk of that gets used up by our generac generator b/c it's not uncommon for us to get at least 5 full days per year when it's running 24 hours per day. this winter has been so freaking cold we've used the fireplace allot more than usual.
