Energy audits in the Salt Lake City area are available for $100 through the Utah Home Performance Program, and depending on your home and your utilities, you can save from 20 percent to 40 percent on your utility bills.

Your home was built before energy efficiency was a major concern for homeowners or builders. The first energy efficiency codes weren't implemented until 1993, and compact florescent lightbulbs weren't invented until 1973. In other words, an energy audit will likely identify a lot of opportunity for savings from simple measures like adding insulation and air sealing around your windows, doors, outlets and lights. You may also find you are ready to upgrade your HVAC and water heating equipment to more energy-efficient models.

For a general idea of exact savings, the average U.S. homeowner spends $2,300 per year on energy bills. If increased your efficiency by 30 percent, you'd save nearly $700 per year on your utilities.
