The Energy Star program, an initiative of the U.S. Environmental Protection Agency (EPA) and the Department of Energy (DOE), was begun in the early 1990s and helps consumers make smart, energy-efficient purchases for their homes.

Products bearing the Energy Star label have the same features and functionality as non-labeled products but use less energy. The benefits include energy-bill savings and a reduction in greenhouse gas emissions. In addition to everything from computers to light bulbs and all major appliances in between, even entire new homes can earn the Energy Star seal of approval.

To qualify for Energy Star certification, a product must meet or exceed guidelines set by the EPA and DOE. The label ensures that a product uses 10%–50% less energy than a similar model. Energy Star appliances also bear the yellow EnergyGuide, which estimates how much annual energy the product will use and its cost compared with that of similar products.

Energy Star products might cost more than their counterparts, but the energy savings gained over the lifespan of a certified product can easily make up for the initial extra expense. And, as additional incentive, many utility companies offer rebates on Energy Star products. Contact your local utility company for more details when considering making a new appliance purchase.
