Upgrade to an efficient washing machine

Why? Washing your clothes uses a significant amount of energy, especially if you use warm or hot water. New, efficient clothes washers use less water and energy than old and conventional washers, resulting in energy savings. Some newer models also allow you to wash more clothes per load and are gentler on your clothes.
What to look for:
  • ENERGY STAR® certified clothes washers. They use nearly 25% less energy and 40% less water compared to non-certified washers. Look up efficient models here.
  • A Modified Energy Factor (MEF) of 2.0 or higher. The MEF considers the energy used by the washer, the energy to heat the water, and the energy used by the dryer. The higher the MEF, the more energy efficient the clothes washer.
  • A low Water Factor (WF). WF measures the amount of water the washer uses. The lower the WF, the more water efficient the clothes washer.
  • The right size. Choose a washer that's sized appropriately for your household.


Added benefits:

  • Wash more clothes. Some front-loading models without an agitator and some advanced top loaders can handle more clothes per load, which means fewer loads are needed to finish the laundry.
  • Gentler on clothes. Front-loading clothes washers are also easier on your clothes, helping them last longer. Advanced top-loaders are also gentler.
  • Dry less. Efficient washers extract more water from clothes, so they dry faster.


Good to know: An ENERGY STAR certified clothes washer will save you the most energy if your current clothes washer was manufactured before the year 2003.
