HIGH-EFFICIENCY DISHWASHERSYou can spend less money on water and spend less time in the kitchen if you switch to a high-efficiency dishwasher. Again, the Energy Star label will point you to the best water-savers. High efficiency dishwashers use about 6-10 gallons of water per load of dishes (some use as little as 3.7 gallons!). Compare that to 9-12 gallons per load for average dishwashers and 20 gallons for hand washing.Many newer models require little or no pre-rinsing of dishes that's more water and time saved.
