i don't know cubic feet, but we have 1800 square feet. I am in Michigan. the house is heated with gas, bill this year with my cuts 250 for two of the months. The electric is never over 28 per month. Daughter watches tv about 2-3 hours a day. I am on computer alot. Laundry is once a week, about 3-4 loads and we line dry. cold water only. I think the key is to unplug everything when not in use. I started many years ago and when i walked around my house it was amazing how many electric clocks there are, i unplugged them all. the stove clock is good and the rest are now battery (have lasted a long time). we read at night, but use lower watt bulbs. happy hunting for savings, you are using a lot of electric appliances.
