If your current clothes washer is about to quit, you should consider buying one that’s Energy Star-certified. Energy Star appliances are better-engineered to save you money on your utility bills and help the environment by using less energy and water. We get our electricity primarily through the burning of fossil fuels, which create greenhouse gas emissions and pollution, that in turn leads to climate change. Energy Star says that clothes washers that earn its label use 37% less electricity and 50% less water than other washers.
The Energy Star program recommends that when buying a clothes washer, you pick one that is an appropriate size. Using a small, super-efficient model more frequently to handle a large amount of laundry is less energy-efficient over time. Energy Star has two metrics to measure washer efficiency. The first is the Water Factor number. The lower the WF rating, the more efficient the washer is in using water. The second metric is the Modified Energy Factor, which takes into account the amount of energy used to run the machine and the amount of energy used to heat the water for it. The higher the MEF, the more efficient the washer is in its energy use.
Here are the top 10 washers as of May 2011, according to the Energy Star website, ranked by MEF. Note that model numbers listed with asterisks (*), have characters that indicate model color, or something else that has no bearing on performance.
