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?
By hand but only because I took the kitchen of the previous tenants and it had none and there is no space to easily install one. If I ever buy a new kitchen I would by one.
