Utility bills will always be a part of your life, but there are things that you can do to make them a smaller part of it.
If you can, get a programmable thermostat for your home. Set it to keep the temperature cooler at night and when you are not at home in the winter, and warmer at night and when you are not at home in the summer.
For every degree higher for air-conditioning and lower for heating, you could save $100 per year on your utility bill. This simple act also cuts down on carbon emissions 1% for each degree.
If you are too cold, put on a sweatshirt or snuggle up with a blanket. I use a space heater to warm the romm I'm in for a while. If you are too hot, close the blinds and turn on a fan. Ceiling fans circulate the air and drop the temperature of the house.
Small changes add up to big savings!
