Energy-efficient upgrades

Upgrading to a newer appliance not only means improved features and performance, it often comes with a huge improvement in energy consumption. For example, it’s estimated that refrigerators that are at least 15 years old use twice as much energy as newer ones, while newer dishwashers use about half the water and energy compared to older ones.

Many new appliances are also Energy Star-certified, which means they meet performance requirements and energy usage criteria set by the Environmental Protection Agency. These appliances, available in 40 product categories, have been tested and reviewed by a third party to ensure they meet these criteria. Since the Energy Star program was introduced in 1992, it’s estimated to have reduced energy costs by $500 billion dollars while also reducing greenhouse gas emissions by 4 billion metric tons.


Consider these other energy-saving features as you shop for a new appliance.
