What makes a washer energy efficient?
Energy-efficient washers use less water than regular washers, which also means less water to heat, so the savings show up on more than one utility bill. These washers, usually front-loading, use a tumbler to cycle the clothes through a small amount of water. They require HE (high-efficiency) detergent, which produces only a small amount of suds and means less rinsing for clean clothes. These washers have higher capacity tubs so you can fit more clothes in, meaning fewer loads.
