If you want the sparkling clean of dishwashers without the waste, energy-efficient dishwashers are perfect for your kitchen. Not only do energy-efficient dishwashers save you dollars on your energy bill; they save gallons of water while still giving your dishes the cleaning treatment they deserve. These new dishwashers are generally 10 percent more efficient than older models and just as effective. Considering the added benefits, there is no reason to not own an energy-efficient dishwasher. If you still have a few doubts, here are some answers on common questions.

Energy-efficient Dishwashers:

  1. Are energy-efficient dishwashers more efficient than washing by hand?
    When washing dishes by hand, you might think you are using no electricity at all. However, some people wash dishes by keeping the hot water running the entire time, which keeps the water heater running. Even if you fill your sink and turn off the water, many people keep the cold water running to rinse the dishes, wasting water. On both counts, energy-efficient dishwashers save both on energy and water. Either way, you will probably save resources with an energy-efficient dishwasher.

  2. How do I know if I am buying an energy-efficient dishwasher?
    Most energy-efficient dishwashers will be clearly marked, but if you want to make sure you are getting what you pay for, check dishwasher ratings. Check for dishwashers that have an Energy Factor of 0.64 or above or an estimated energy use of less than 340 kWh per year. It couldn't hurt to read a few dishwasher reviews to see how energy-efficient dishwashers perform in the real world.

  3. Can I make an energy-efficient dishwasher more efficient?
    Yes you can. Although you won't be able to make any adjustments to the actual dishwasher, you can change a few of your own habits to maximize the efficiency. Wait until you have a full load in your dishwasher before turning it on. Instead of wasting water and energy on small loads, get everything done in one fell swoop. Most energy-efficient dishwashers will wash dishes effectively at a temperature of 120 degrees Fahrenheit, so turn down your thermostat. Also, don't waste water by rinsing dishes before you place them in the dishwasher. Scrape off the food and let the dishwasher do its job.
