Choose an ENERGY STAR® qualified dishwasher
Natural Resources Canada states that an ENERGY STAR certified dishwasher uses 12% less energy and 30% less water on average than a standard model. ENERGY STAR® certifies that your dishwasher won’t use more than 15 litres of water. Filling your kitchen sink to hand wash dishes likely uses 20 litres or more.
Numerous ENERGY STAR® rated dishwashers are available, in pretty much every price range. As well as ensuring you buy ENERGY STAR®, look at the EnerGuide rating to be sure the dishwasher you buy is the most efficient one that will meet your needs.
