While, I know that not everyone has the ability to do this, we cut off our heat and use our wood burning stove to heat our home. While others have electric bills over $300/month, ours have been under $200.00. We make an effort to turn off lights, use smaller wattage lightbulbs in our lamps. We watch how much laundry we do and the size of the loads. We grow alot of our own food and I can and freeze it in the summer.
