Dishwashers do not drain your energy as much as other appliances, but if you want a home that is energy-efficient through and through, then you’ll certainly want to ensure you have a modern, energy-efficient dishwasher. In addition to energy consumption, you'll want to consider the water usage of your dishwasher. Modern dishwashers have all kinds of technologies meant to maximize water usage, including soil sensors to test how dirty your dishes are and how much water and heat will be needed, clean-water rinse cycles, efficient spray jets and strategic dish rack designs that ensure every dish gets a complete cleaning.5
Consider the size of the dishwasher you need. If you are more inclined to wash dishes by hand or you simply don't use very many dishes, you can probably purchase a smaller dishwasher. There are even countertop-sized dishwashers available for people who might lack space for a full dishwasher, renters who want a dishwasher they will be able to move to their next home or people who use very few dishes and don't want to run their full-size dishwashers. Just be sure you get the right size for your household needs. If you get too small a dishwasher, you could end up running the dishwasher more often, which will reduce your savings overall.
Whichever dishwasher you select, be sure to choose one with several washing options — and then use those options. Choosing a lighter wash whenever possible will help cut down on water and electricity costs. And stay away from the heated dry option. It's usually not needed and can rack up energy costs with little to no benefit to you.
