Dishwasher uses less water than washing by hand
It's official! It's better for the environment if you use a dishwasher than wash dishes by hand. LOL.
Don't think this really resolves the issue, except maybe regarding water usage - doesn't consider electricity or very frugal methods for hand washing by some or the footprint made by materials and manufacturing needed to construct machine or transport to your house or dispose of when replacing, probably other considerations too but thought I would post for those who are interested like I am in considering the environment when we make such choices in our life.
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.
