Q&A: The Dishwasher vs. Washing Dishes By Hand
Written by Leah Ingram . May 13, 2009
Which one is better? The answer might surprise you.
Last year, I addressed a reader question on my blog about whether it was more eco-friendly to use paper plates rather than run the dishwasher-the answer was to go with the dishwasher, which surprised many people. In response to that, another reader wrote with a related question. I'm sure it's a quandary all of us green and frugal folks have considered at one time or another:
Is it more green to use a dishwasher or to wash by hand? I don't own a dishwasher, and I wash "Asian" style with a small bowl of hot soapy water to dip the washcloth in, scrub the item, then a quick hot rinse from the tap, then onto the drying rack. My husband has always argued that a dishwasher would be more efficient with the water, but I don't see how it could be. What do you think?
The next time that you wash dishes by hand, here's an experiment I'd like you to try. Stop up the sink over which you hot rinse the dishes, and then at the end of the wash cycle, measure how much water is in there. I'll bet it's more than you thought you were using, because when it runs down the drain, you don't see it. How many gallons did you end up with?
I'm suggesting this experiment because, unbelievably, newer, efficient dishwashers use as little as five gallons of water for the entire dishwasher load. On the other hand, says the American Water Works Association, when you wash dishes by hand, the average person uses 20 gallons of water. Now maybe this figure comes from those that leave the tap on as they're washing and aren't conservative with water the way you are. But I'll bet that it would be a challenge for you to hand wash an entire day's worth of dishes using five gallons only-for the dipping, washing and rinsing.
Considering that you don't own a dishwasher, you don't have one as your back-up option, and I would suggest you continue to wash your dishes in the water-saving manner you've been using. But in the future, you may have to question whether getting a dishwasher does make sense as a water- and time-saver.
