Washing machines are second only to toilets as the largest water users in the home, accounting for 14 percent of household water use. Household water consumption has a significant impact on aquatic life as well, especially when water supplies are drawn from freshwater lakes and rivers where only 1 percent of readily available water is freshwater. To help save the environment and reduce the amount of freshwater we use, energy-efficient washers use up to 50 percent less energy and 60 percent less water than standard machines. These new washing machines are 37 percent more energy-efficient and use 18 to 25 gallons per load, about half what traditional washers use, which can save a lot of money on your water bill! Listed here is Green Guides list of most efficient washing machine companies.
