As temperatures drop, energy bills can climb higher. Take a walk around your home and check the weather stripping on doors and windows. Also, check to see how well the trim (on the exterior) around doors and windows is sealed (caulked). Making improvements in these areas is cheap and easy enough to do yourself.
Additionally, check the temperature of the hot water in your home. You can do this by using a basic meat thermometer and just hold it under the hot water faucet. Hot water need be no hotter than 125 degrees. If it’s hotter than this, your energy expenses will lower as you lower the temperature.
