Energy Star washing machines typically have features such as sensors that prevent energy waste by matching water needs to the size of the load. As well, energy star models have advanced high speed motors that reduce the length of spin cycles and remove more water from clothes, so less time and energy are required to dry your clothes.

In order to qualify for the Energy Star label, a washing machine must:

  • be at least 36 percent more efficient than the minimum federal energy performance standard in Canada’s Energy Efficiency Regulations
  • use at least 35 percent less water than a standard washing machine
  • As of July 1, 2009 a washing machine must have a Modified Energy Factor (MEF) of at least 1.8 and a Water Factor (WF) of less than 7.5. The MEF is a calculation that takes into account the amount of energy required to run the machine along with the dryer energy required to remove the remaining moisture content. The WF is a limit on the amount of water used in a washing cycle that takes into account the capacity of the washing tub.
  • As of January 1, 2011 a washing machine must have a Modified Energy Factor (MEF) of at least 2.0 and a Water Factor (WF) of less than 6.0.

Another benefit of Energy Star machines is they will use less detergent than standard washing machines.
