The previous two Green Tips discussed how much treated, potable water we waste, and how toilet flushing is the No. 1 water user. Another high water user is the washing machine. Today’s generation of washing machines use half the water of older appliances that required up to 40 gallons of water per load. Additionally, higher spinning rates on the final cycle squeeze more water out of our clothes so that energy by the dryer is reduced. Consider upgrading your washing machine!
