Which Is Better For The Environment: Washing Dishes By Hand Or The Dishwasher?

Which Is Better for the Environment: Washing Dishes by Hand or the Dishwasher?By Wendy Ruopp, managing editor of EatingWell Magazine

Anyone who's ever watched a teenager (grudgingly) wash one fork at a time when it's their turn to do the dinner dishes has probably had the thought "I wonder if that's really the most efficient use of our resources." Actually, your first thought is probably, "How does the child manage to run the hot water continuously yet get the task done at such a glacial pace?" (Don't Miss: How to Save Time in the Kitchen: Our Best Time-Saving Ingredients & Cooking Tips) In any case, your suspicions that it's really not the best thing for the environment are borne out by research.

A study out of the University of Bonn in Germany, reported by Pablo Päster in the May/June issue of EatingWell Magazine, found that washing a load of dishes (12 place settings) by hand uses on average 27 gallons of water and 2.5 kilowatt-hours of energy to heat the water -- equivalent to running a hair dryer for two and a half hours. (Not to mention the parental energy it takes to get your kid to wash all those dishes in the first place.)

By comparison, an energy-efficient dishwasher uses about four gallons of water and 1 kWh of energy per load. (And over the course of a year, using the dishwasher saves more than 400 hours of labor!) Researchers also found that dishwashers cleaned better, as half of the hand-washers failed to reach an “acceptable level” of cleanliness.

As far as we know, the researchers shed no light on how to get your family to load the dishwasher properly, start it when it’s full and then put the clean dishes away without complaining about it.

Lower your carbon footprint even more -- and save money -- with these tips:
• Scrape food off plates before loading the dishwasher, but don’t pre-rinse.
• Only run a full load and load it per the manufacturer’s suggestions for maximum cleaning. (Don’t Miss: 9 Green Products for a Healthy Kitchen.)
• No dishwasher? Hand-wash dishes right away (you’ll use less water when there’s no stuck-on crud).

Do you primarily wash your dishes by hand or use a dishwasher?

Sure, an "energy-efficient dishwasher uses about four gallons of water" - but what about the average dishwasher? How much water and energy is used by the dishwashers most people can afford and live with - including the water used by those who clean the dishes before placing them IN the dish washer (and use the dishwasher primarily for heat-sterilizing the dishes)?

Or perhaps someone could research how little water is used when someone who is conscious of water use does the same quantity of dishes by hand? I doubt that such a person would use anywhere near 27 gallons..........

I use my dishwasher for the items that can and should go into the dishwasher, but I wash some things by hand.

Also add in to the dishwasher cost that like most newer things these days it is always on. The drain is slight of course, but it is another of those vampires constantly using electricity. I unplugged the dishwasher when I became single again. The amount of dishes I dirty is too small to leave for a full load.

You don't have to run the water continuously to rinse the items. And what about the energy it takes to make and sell dishwasher products? Extra packaging and fuel to distribute VS dish soap and a sponge. I add a bit of vinegar or bleach to the soapy water and you don't have to fill a whole dishpan to soak dishes. You spray to pre-wash and just dip your sponge in the water; if you keep your water clean, you can use the wash water at least twice and disinfect your sponge in between. You only have the tap on to rinse the items as needed and for pre-wash. And you can have half your clean-up done while your food is cooking; get all the prep utensils done before the food is ready. It's easy.

Sorry to see so many posters had poor experiences with their dishwashers. My Bosch is my favorite appliance and it does a splendid job. I found that Finish Advanced Deep Cleaning Powder far outperforms Cascade for best results. Run the tap to get the water hot just before the cycle begins. If your dishwasher once performed better than it does now, there are cleaning products in the dishwasher detergent section that you can run through in a single cycle; they remove buildup and make a big difference.

Some have spoken of how they value family time spent doing dishes together. That's great. As for me, I'm single, busy, and couldn't be happier to have this workhorse doing a great, economical job with what (for me) would be a repetitive and time-consuming daily chore.

Pre-rinse? That's what the dogs are for! And unlike teenagers, they LOVE helping out with the dishwasher.

(And in case you decide to whine and feel faint about hygiene - this is why my family have immune systems tougher than old shoe leather.)

With a double sink design, fill one sink with soapy water. Let soak. Wash each dish/ item, rest on toweled countertop or in dry sink.
Turn on water to rinse each item. Turn off between longer tasks. Do not run the water unless you are filling the sink or rinsing. Seems a painless way and is quick and sensitive to water use. Key is not to just run the water unless actually using it. It's better for the ecology!

We did this growing up since we didn't have a dishwasher. It's an ok method, and I still do it when I'm cooking just for myself. But considering how much my sibling and I fought about dish washing growing up, I'm inclined to think that a dishwasher would have made our lives easier. Or at least given us more time to fight about other things. :)

It's a fact, DW's are MUCH more efficient than hand washing. They key is not to use the dry cycle, just let them dry on their own.

27 gallons? Where they washing their dishes in a bathtub? You need two sinks, one for soaking and one for washing and you don t need 27 gallons to clean a 12 person diner. 27 gallons is equivalent to 105 bottles of water. Are you kidding me? Who wastes that much water? Its like a full bottle of water per plate, fork, spoon etc...

The dishwasher uses 4. They are MUCH more efficient than hand washing as long as you let then dry themselves (the dry cycle uses energy).

Hand dishwashing is exercise for the human dishwasher. It is the sharing of kitchen and table cleanup after dinner. Cleaning the dishes properly is a small and easily met challenge for a person of reasonable intelligence. It is not directly fossil fuel powered except for the hot water used, which electric dishwashers also use and reheat with electric resistance continually through the wash and dry cycles, even if they use less. The only "machine" required is made by nature and fueled by the meal eaten. It is time spent serving others and keeping the home clean and safe. It is not in any significant way 'bad' for the wider environment. Nor can such an absurd claim be fairly made by a reasonable person.

Don't forgets the benefits of the "sanitize"setting on the dishwasher. For those who don't like germs, or course.

That is crap. For a place serving of 12 would mean all of the dishes and pots and pans used wouldn't fit in the dishwasher and require some hand washing or more loads. And I have to almost clean my dishes before putting them in the dishwasher anyway. I don't agree with this study.

Our dishwasher is broken but we only do a few dishes at a time anyway. Come to think of it, if we were going to need 12 place settings we would have to borrow half of them from the neighbors.

There are quite a few ways to conserve water while hand washing your dishes. Try a low flow aerator and dumping the rinse water on plants.

Not in my experience. I've had some fig trees and blackberry bushes that only get greywater from my washer and they've been thriving for 4 years.

after reading some comments about germs, I wonder. In our efforts to eliminate germs, have we made ourselves more vulnerable to disease by lowering our bodily constitution and our immune system. Bacteria constantly evolves and if our bodies do not have to fight simple bacteria improving our immune systems, are we making ourselves prone to the more serious types of bacteria?

I got four boys, ages 9 thru 18 and they create a lot of dirty dishes as you can imagine. Long story short, even though I load and unload the dishwasher almost all the time, the bride decided to wash them by hand. She thinks she is saving electricity but she ignores excess water and natural gas consumption. I think she's lost it. Why would you bother if your husband took care of clean up anyway?
