Ways to cut the cost

  • 1

    Wash in cold water — 90% of a load's energy goes to water heating

    Saves 200-400 kWh/year

  • 2

    Run full loads — partial loads waste water and energy

    Cuts total washer use 30-40%

  • 3

    Upgrade to HE front-loader at replacement time

    Front-loaders use 40-50% less water and energy
