Have a cool green laundry day

By far the biggest percentage (up to 90%) of a washing machine's energy consumption goes into just heating the water. Save energy on doing laundry by washing your clothes in cold water, or using the warmer wash settings less often. Washing in cold water helps your clothes last longer and will usually be quite sufficient to get them clean.
