Read the instructions for your dishwasher to make sure you're taking advantage of all its energy saving features. For easy-to-clean loads, use the light or short cycle. Use the no-heat or energy saving drying cycle for further savings. If you don't have that feature, open the dishwasher door when the wash cycle is complete and let the dishes air-dry. And always, wait until the dishwasher is full before you run it.
