Question: how many gallons of water do you use to wash dishes?
Answer: Getting them clean in the sink can use up to 27 gallons of water per load. An Energy Star certified dishwasher can use as little as 3 gallons per load (around 11 litres), according to the Natural Resources Defense Council. In fact, an Energy Star certified dishwasher can save almost 5,000 gallons of water per year.
