Newly-manufactured clothes washers for homes, multi-family buildings and laundromats are good candidates for customer incentive programs aimed at saving energy and water.
Efficiency standards taking effect Jan. 1, 2018, will reduce energy use in residential top-loading clothes washers by 18 percent and water use by 23 percent. The standards for the generally more efficient front-loading washers were increased in 2015 and will remain unchanged in 2018.
Combined, the changes in the 2015 and 2018 standards will eliminate the need for 1.3 gigawatts of electricity generating capacity over 30 years, according to a Department of Energy estimate. That is roughly the output of two average-sized coal plants. For water utilities, the new appliances will save 3 trillion gallons of water over the same period of time, and consumers can net up to $30 billion in savings.
Commercial washers, of the type used in multi-family buildings and laundromats, will see energy use reductions of 15 percent for top-loading models and 18 percent for front-loaders. The standards will also cut the water consumption of front-loaders by 20 percent, while the water use of top-loaders will remain essentially unchanged.
A blog post by the Appliance Standards Awareness Project goes into depths on the history of standards for clothes washers, along with the benefits to consumers and the potential for more savings. Electricity and water providers stand to gain new tools to meet their load management goals and build stronger customer relationships, making strong efficiency standards a win for everyone.
