As 2010 drew to a close and everyone around the world celebrated with fireworks and noisemakers, I had just one thing on my mind: Did my dishwasher fulfill its green promise? As I reported last January, we welcomed our trusty Energy Star appliance to the family after an entire adulthood of hand washing dishes.
Oh how wonderful these last twelve months have been! No more hours hunched over a sink full of dirty dishes. Just stacks of sparkling clean plates, forks, pots, and pans. And the best part is–the dishwasher saves water and energy over even the thriftiest hand washer!
Or so I’d heard. After a year-long study (sample size: 1), we ran the numbers. Did we save water in our Year of the Dishwasher compared to the previous year? The answer: no. We used almost the exact same amount of water both years. How could this be? Were we thriftier than the thriftiest hand washer after all? Maybe the dishwasher couldn’t compete with that.
