A simple way to save over $180.00 a year on energy bills is to install a programmable thermostat. The cost is less than the savings and the savings will be around for years to come. These type of thermostats prevent energy waste because you can control when and when NOT to heat. Have your heating and cooling systems checked annually to be sure they are running properly. Be sure to caulk and seal windows and doors etc and save even more PLUS you will be warmer (or cooler in the summer). Energy Star has some tips for sealing that may be helpful.
