Looking at reviews to find the best, energy efficient dishwasher for your home? Good idea!
Your home appliances can really add to your energy bills — and your carbon footprint.
If you’re in the market for a new dishwasher, look for a model that’s Energy Star certified. Energy Star is a program that was started by the U.S. Environmental Protection Agency in the 1990’s. It created a certification standard for energy-efficient computers and appliances. The EPA says that in 2006, $14 billion were saved in energy costs through the implementation of Energy Star products.
Here’s a list of the top ten best dishwashers available in the U.S. in 2011, ranked strictly by efficiency. Most of these are premium dishwashers, so you’ll also get a quiet dishwasher that cleans well too. Model numbers with asterisks (*), contain characters that denote color, or another variable unrelated to energy efficiency. This list was compiled using Energy Star’s Energy Factor criteria, which is a measurement of energy use per cycle. The higher the Energy Factor, the better.
When shopping for dishwashers, Energy Star recommends buying one with an appropriate size. Dishwashers that are run full are the most energy-efficient. Standard-size models tend to hold 8 or more place settings, while compact (drawer) models hold 7 or less. Get a compact model if you only generate a few dishes on a daily basis. Also, dishwashers with multiple wash-cycle options (for lightly-soiled dishes, for example), can help you save additional energy.
