Dishwashers in the U.S. use 24,000 GWh of energy per year. There are both technology and behavioral opportunities to increase the energy efficiency of dishwashers. Technology options include dishwashers with cold-water inputs, more efficient dish configurations, and flow-through heating. Water efficiency is another consideration with dishwashers, as improved water efficiency may help to increase energy efficiency.
