How to Save Energy on Laundry
🇩🇪 Diesen Artikel auf Deutsch lesenWash in cold water, run full loads, use the highest spin speed your clothes tolerate and air-dry when you can. According to ENERGY STAR, about 90% of the energy a washer uses goes to heating water, so switching to cold makes the biggest difference.
Laundry adds up: several loads a week, hot water, and a dryer that's one of the biggest electricity users in many homes.
Step by step
- Switch to cold water
Modern detergents clean well in cold water. Use warm or hot only for heavily soiled items or for hygiene needs.
- Run full loads
Washers and dryers use nearly as much energy for a half load as for a full load.
- Use a high spin speed
The more water the washer removes, the less work the dryer has to do.
- Clean the lint filter every load
A clean filter improves airflow and shortens drying time.
- Use moisture sensing
Choose sensor dry instead of timed dry so the dryer stops when clothes are dry.
- Dry loads back to back
A warm dryer uses less energy for the next load.
- Air-dry when possible
A drying rack or clothesline costs nothing to run and is gentler on clothes.

Do I need special detergent for cold water?
Most detergents work in cold water. Products labeled for cold washing can perform even better at low temperatures.
Should I upgrade my washer?
ENERGY STAR washers use less water and energy. If your washer is old and needs replacing, efficiency is worth considering.
