Making our homes as energy efficient as possible keeps utility bills down and helps us preserve precious natural resources for future generations. Our homes use energy in a variety of ways to provide comfort, convenience and entertainment.  Some systems in the home use energy directly, like our appliances and lighting. Other homes systems impact how much energy the home uses even though they use no energy themselves, like the walls and windows. 

Learning how home systems use energy can help identify opportunities for savings and home improvements.
