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?

dishwasher. it uses way less water than even filling the sink once. it obviously uses more electricity than doing it by hand though. you gotta think about the value of the time saved as well.

Depends whether you wash in hot or cold water. If you use more hot water washing dishes by hand then it'll consume more electricity too.

I use a dishwasher. Produce all my own power so that’s not a concern. Also on a treated well system so it really just makes more sense.

Generally wait until it’s full before I run it but yeah. Inefficiency is the enemy.

I used to wash by filling the sink till I met my wife - she always wet each item, scrubbed with soapy scrubber, and then rinsed. It's a far better method!

That's like the second most wasteful way of washing dishes, with the most wasteful being the same thing but not turning the tap off while scrubbing.

Well, presuming you have enough wares for a full wash. Filling the sink for just one plate would be unnecessary...

You can plug the sink and wash with your current tap method and see how many dishes it takes to fill the sink with water - that's how many you need to collect to save water with the sink method.

That's what I thought, so that's what I did! Way less water than filling the sink. Way less. I will add though that I have a pretty big sink.

Cool! My sink was small enough that I'd fill it thrice while washing under the tap haha. Now I have a washing machine and won't be going back.
