Modern dishwashers are impressively efficient. Unless you’re employing the most scrupulous hand-washing technique, machine-washing your dishes generally saves both water and energy. Some dishwashers use as little as 3 gallons of water per cycle, while hand-washing can require up to 27 gallons.

In our evaluations of dishwashers, we not only test models for their capacity to clean and dry dishes but also factor in how much energy and water they use during operation. If you’re looking for an energy-efficient dishwasher that gets your dishes clean and dry, below are five of the highest-performing models in our ratings that also score well for energy efficiency. For a wider selection, you can check our complete dishwasher ratings for more models that earn a top-notch rating for energy efficiency.
