You keep your house at 70 degrees year round, yet your bill is higher in the winter. Why?
The colder the temperature outside, the more electricity you will use to maintain heat in your home.
For instance, it is a lot harder and requires more electricity to keep a home at 70 degrees when the temperature is 20 degrees outside, then during the summer when it is 90 degrees outside. When it is 20 degrees outside, and you are keeping your home at 70 degrees, that is a 50 degree difference. When it is 70 degrees in your home but 90 degrees outside, then that is only a 20 degree difference, making your air conditioner not work as hard, not using as much electricity.
