If you have an automatic dishwasher, use it. It consumes a third less
water than hand washing, which saves energy and money. Tips for operating
your dishwasher efficiently include:
Avoid pre-rinsing dishes before putting in dishwasher. Use your rinse
cycle until it's time to clean a full load. It can save up to $70 a
year.
Use the energy-saving cycle to shorten the run time and save gallons
of water.
Use no-heat drying.
When shopping for a new dishwasher, follow these simple tips:
Compare features - look at models that offer energy-saving features.
Compare prices and check the Energy Guide label
for operating costs of the models you're considering.
Consider the machine's water usage - over 80 percent of the energy used by
dishwashers is for heating the water. Therefore, models that use less water
use less energy.
