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?
Dishwashers are not a thing where I live.
I wash my dishes in at least two passes. First (optional) pass is to remove the gunk, no soap, as little water as possible. Second is to apply soap, with just enough water to wet the surface for the soap to work. Third pass is the rinse, and this is where most of the water consumption happens. I plug the sink, put the soapy dishes in the sink, and let the slightly soapy water from the current item fill it, making sure that the rest of the items consume as little water as possible even in this step.
I think for an after dinner washing for a family of four, I take around 10 minutes for the entire thing.
