    Wash clothes in cold water

    Water heating consumes about 90% of the energy it takes to operate a clothes washer. Unless you're dealing with oily stains, washing in cold water will generally do a good job of cleaning. Switching your temperature setting from hot to warm can cut energy use in half. Using the cold cycle reduces energy use even more.
