Air Dry Your Dishes
By using a dishwasher, you actually save water and energy over hand washing dishes. You can save even more energy and time when doing the dishes by not rinsing your dishes before putting them in the dishwasher. Scrape them clean of food debris before placing them in the dishwasher. Choose the cycle that matches the dirtiest dishes in the dishwasher load. Avoid choosing cycles that use the extra heat options whenever possible.
Did you know:
Air drying is the best way to dry your dishes without encouraging the growth of bacteria.
Now, if the debate is between washing dishes by hand or using a dishwasher, then the dish-washer wins.
What to do:
Select the air-dry cycle instead of the heat dry cycle for drying the dishes after the load is complete.
If you don't have this option on your dishwasher, when the load has finished washing, turn the dishwasher off and open the door a crack to let the dishes dry. This keeps available heat inside, but allows the dishes to air-dry. This saves about 15 percent of your total dishwasher's energy use.
