Energy Guide Labels

PrintPrint

All major home appliances must meet the Appliance Standards Program set by the US Department of Energy (DOE). Manufacturers must use standard test procedures developed by DOE to prove the energy use and efficiency of their products. Test results are printed on yellow Energy Guide labels (pictured below) which manufacturers are required to display on many appliances. This label provides the necessary information to perform a Life Cycle Analysis when comparing different models.

Instructions: Click on the numbers below to view detailed descriptions about the information found on Energy Guide labels.

The Federal Trade Commission's Appliance Labeling Rule requires appliance manufacturers to put these labels on refrigerators, freezers, dishwashers, clothes washers, water heaters, furnaces, boilers, central air conditioners, room air conditioners, heat pumps, and pool heaters. The law requires that the labels specify:

  • the capacity of the particular model—for refrigerators, freezers, dishwashers, clothes washers, and water heaters;
  • the energy efficiency rating and the estimated annual energy consumption of the model—for air conditioners, heat pumps, furnaces, boilers, and pool heaters;
  • the range of estimated annual energy consumption, or energy efficiency ratings, of comparable appliances.

How to Use the Labels

A worksheet on how to use the labels in choosing a cost-effective and environmentally friendly appliance is given below.
