Is there a real difference in water and electricity consumption? Personally, I don’t use a lot of water to wash my dishes (by hand), but maybe I should install a flow meter to make sure.
What is your opinion on the subject? Do you have any evidence or studies available that could confirm your intuition? Or do you have other alternatives in mind?
It’s not just hand washing like that. They have done comparisons with varieties of hand washing. Basically the only type of hand washing that saves water when done frugally is the three sink/basin method.
