- Wash and dry full loads. Washing full loads can save you more than 3,400 gallons of water each year.
- If you are washing a small load, use the appropriate water-level setting.
- Doing full loads of laundry in the washer saves both energy and water. Sort and organize your laundry so that you will be doing full loads. Be careful not to overload the washer. Your clothes may not get fully clean and may need to be washed again.
- Wash your clothes in cold water using cold-water detergents whenever possible. Hot water heating accounts for about 90 percent of the energy your machine uses to wash clothes — only 10 percent goes to electricity used by the washer motor. Depending on the clothes and local water quality (hardness), many homeowners can effectively do laundry exclusively with cold water, using cold water laundry detergents. Switching to cold water can save the average household more than $40 annually (with an electric water heater) and more than $30 annually (with a gas water heater).
