Robi, in the winter when the temps get below 50 at night, I pay $750/mo. to run the heat. In the summer when the temps are above 90, I also pay $750/mo. to run the air. In the spring and fall, when it's nice and I don't need the air or heat, I pay at least $400-500 mo. Remember, I have 4 women in my house, they take long hot baths or showers, sometimes several in a day. And with 4 kids, the washer and dryer never stop running. The house is fully electric, no gas or oil. Also, the house was built in 1962, when electricity was about a nickle a KW, so it has no insulation and most of the back wall, facing the lake, is glass. Single pane sliding door type glass. So when it's 40 outside, it's 40 inside, the (electric) heater never stops running.

Here's the funny part. Florida is "The Sunshine State" yet it has no real solar power program!
