About 90% of the energy used for washing clothes is for heating water. To reduce this energy usage you can use less water or use cooler water.
Laundry tips:
- Wash your clothes in cold water using cold-water detergents whenever possible. Unless you are dealing with oily stains, warm-water or cold-water washing will generally get your clothes clean. Switching from hot to warm water can cut a load's energy use in half.
- Wash and dry full loads. If you are washing a small load, use the appropriate water level setting.
- Dry towels and heavier cottons in a separate load from lighter-weight clothes.
- Don't over-dry your clothes. If your dryer has a moisture sensor, use it.
- Clean the lint filter in the dryer after every load to improve air circulation.
- Use the cool-down cycle to allow the clothes to finish drying with the residual heat in the dryer.
- Periodically inspect your dryer vent to ensure it is not blocked.
- Air-dry clothes on clothes lines or drying racks whenever possible.
