Our current house is 3300SF, our electric bills are between $350 and $500 a month, depending on AC usage. We have gas stove/heat/hot water. Our previous house was only 1800SF and the same amount of money. We use between 5 and 10 computers, but only 3 or 4 monitors, which are off most of the time.

I feel like we're missing something because other people we know in the same line of work, all say they're under $100 a month.
What's your home size and electric bill?
