  • Lighting and refrigerators come next.
  • The average U.S. household uses about 10,500 kWh a year, but use varies widely by region and home type.
  • Your own bill and appliance labels are the best place to start.

What this guide covers

Start with your own bill and appliance information. The details depend on your home, equipment and the information on your own bill or appliance label.

The biggest uses, by EIA data

EIA reports that in 2020 air conditioning made up about 19% of residential electricity use, space heating about 12% and water heating about 12%. Homes in the South are more likely to have electric heating and use more air conditioning.

Find the big users in your home

  • Compare your bill’s kWh by season. A summer spike points to cooling; a winter spike points to electric heat.
  • Check whether your water heater, dryer, range and heating are electric.
  • Look for second refrigerators or freezers, pools, hot tubs and EV charging.
  • Use EnergyGuide labels to compare appliances.
