Our house is 3500+ sq. ft. (200 year old farmhouse) and we have electric for everything but heating, which is oil. Our electric generally doesn't top $90 and that's even with using more electric means for warmth to shift costs from the oil - things like electric blankets, ceramic heaters and so forth. Here is SE Pennsylvania we only use AC during the very hottest months of the year, and then only in three or four rooms in the house which we can close off. All things considered, I'd say we have it good!
