While running a full dishwasher is the most energy- and water-efficient way to take care of the dishes, even running a half load is better than handwashing. Whether it's a full load or half, dishwashers still use 80% less water than washing by hand. And in terms of energy costs, running the dishwasher can save over $100 a year. Just keep in mind that a half load is still less efficient than a full load, so run it only if you absolutely must.
