Use dishwashers

The average dishwasher in US homes today uses 8.7 gallons of water per load. Washing by hand for 10 minutes with water running can use 20 gallons.

Today’s dishwashers are about 95% more energy-efficient than those bought in 1972—your old dishwasher may be costing you more in energy bills than it would take to buy a new one.
