Ever wonder which type of dish washing is better for the environment?
The answer to this one may surprise you. A few years ago, the University of Bonn in Germany compared the amount of water and power used when washing a full load of dishes in a modern Energy Star dishwasher versus washing the same amount of dishes by hand. The dishwasher was the clear-cut winner, using only one sixth the amount of water, slightly less power (to heat and pump the water, in the case of hand washing), and less soap. Of course, buying a dishwasher costs money, and its higher efficiency won’t pay off the purchase price right away. But if you already have a dishwasher, go ahead and relax. Letting the dishwasher take care of those greasy cooking pots is as good for the environment–and your wallet–as it is for your sanity.
