Clothes Washers with Energy Star Ratings

U.S. Department of Energy Implements More Stringent Criteria for ENERGY STAR® Clothes Washers, Expands CFL Program

The U.S. Department of Energy (DOE)  announced more stringent criteria for clothes washers under the ENERGY STAR® label in 2008.

Based on first-year projected sales data, approximately 1.9 million ENERGY STAR®-qualified clothes washers will be sold, saving American families up to $92.4 million annually on their water and utility bills.

The more stringent requirements for clothes washers carrying the ENERGY STAR® label will take effect in two phases. In order to qualify, clothes washers must be a minimum of 43 percent more efficient than current federal energy efficiency standards with a maximum Water Factor (WF) of 7.5, as of July 1, 2009. As of January 1, 2011, clothes washers must be a minimum of 59 percent more efficient with a maximum WF of 6.0. WF measures the water efficiency and is calculated as gallons of water used per cubic foot of capacity – the lower the WF, the more efficient the clothes washer.

Following the 2011 criteria change for clothes washers, consumers are expected to save $120 million on utility bills annually, 11.2 billion gallons of water and 659 million kilowatt hours of electricity.

Current ENERGY STAR-qualified clothes washers use 75 percent less energy than clothes washer models manufactured in 1980. The ENERGY STAR® criteria for clothes washers, last modified in January 2007, were drafted with input from stakeholders and public review and comment.
