Avoid common energy wasters when it comes to dishwashing. Rather than pre-rinsing dishes, which can use up to 20 gallons of water alone, simply scrape food into the garbage. Run the dishwasher only when it’s full, and select the no-heat drying option to save up to 20% on energy bills.
- Skill level: Basic
- It’s easy to save energy by using your dishwasher the smart way. This appliance uses about the same amount of energy and water per load, no matter how many dishes are inside, so wait until it’s full to run it. Lower the water temperature to 120 F and use eco-mode if available to reduce energy use 20%-30%.
- Cost range: Free
- Running your dishwasher as efficiently as possible won’t cost a thing.
- Savings: $40 annually
- Besides saving water and electricity, you’ll cut down on heat generation when you choose no-heat drying, which can be kinder on top-rack plastic dishes, too. Also, using an ENERGY STAR certified dishwasher instead of hand washing will save 5,000 gallons of water and $30 in utility costs each year.
