Skip the sink wash
Upgrade your dishwasher
In the United States, the most efficient ones carry the Energy Star label. Some machines use just 2.3 gallons of water for a full wash cycle—about the same amount you’d use in one minute of running the kitchen tap.
Scrape, don’t rinse
It can be a hard habit to break, but you don’t need to run your dishes under the faucet before putting them on the dishwashing rack. If there’s dried-on debris, use the dishwasher’s rinse feature instead of doing it yourself.
Let the dishes air-dry
When you press start, be sure your dishwasher’s heated dry feature is off. Thanks to the energy saved, you’ll lower the carbon footprint of the cycle by more than 10 percent.
Of course, some dishwashing jobs require elbow grease. If you do hand-wash, turn off the tap while you scrub and use two filled basins: one with hot, soapy water for washing and another with cool water for rinsing.
