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?
Depends on the type of equipment. Usually there’s a reason like there is a seam that you don’t want water pummeling constantly or with knives you don’t want them banging into other stuff and getting dull.
For a lot of good equipment in the sense of plates, food containers and stuff, the dishwasher is able to rinse at a much higher temperature than what hands can tolerate and will be able to get sanitized. So dishwashers are better in this sense as well if you want to sanitize your dishes without using a bleach rinse.
