My dishwasher uses less then half a sink of dishwater. Add rinsing water and I've wasted more water then the dishwasher uses. The power used is pennies a load. My washer is auto fill. The clothes don't sit in a tub of water the water is sprayed on the clothes. Less drying time, the clothes are almost dry coming out of the washer. Same with dishwasher, the new appliances cost pennies to use.
