Earlier quoted context omitted.
I've read that a dishwasher is less wasteful than hand-washing of dishes (perhaps this isn't true for people who are very, very scrupulous about their use of water while washing dishes, but that's not most of us).
Absolutely. A dishwasher in the average American household, unless they're having massive dinner parties every night, is wanton arrogance. They not only use more resources than handwashing, it also takes longer.
The water usage is almost a 10x difference and the power usage of handwashing is 2/3 more:
"A European study comparing hand washing to machine dish washing found that hand washers used as much as 27 gallons of water and 2.5 kilowatt-hours (kWh) of energy to wash 12 place settings, compared with the 4 gallons and 1.5 kWh used by a hyperefficient dishwasher to wash the same number of dishes."
