Depending on the brand and model, a clothes dryer uses between 1,800 and 5,000 watts, according to the U.S. Department of Energy. On average, dryers use approximately 3,000 watts per hour. Over 4 percent of a household's energy consumption comes from using a clothes dryer.
Based on residential clothes dryers used in the United States, the Environmental Protection Agency (EPA) estimates an annual:
- Consumption of 43 billion kilowatt hours of electricity
- Consumption of 445 million therms of natural gas
- Emissions of 32 million metric tons of carbon dioxide (CO2)
The EPA predicts advances in dryer technology, including heat pumps, will help make dryers more energy efficient and reduce harmful CO2 emissions by up to 30 percent.
The best way to save on overall household energy costs is to limit dryer use by hanging clothes to dry.
