I'm in California and have no air conditioning. My electric bill still runs over $100 per month normally, and on really cold months where we use the fan to blow the gas heater, it can be as high as $300.

I love summer when my gas and electric bill are at their lowest - it helps pay for the extra water we use!

I think ours is so high because we normally have three computers going, various TVs and radios, and we do not have dual pane windows - which we hope to add this fall. That will really help on our electric and gas.
