Energy Star

Energy Star (trademarked ENERGY STAR) is an <a href="/facts/Efficient_energy_use/8K8vBAVk">energy-efficiency</a> program administered by the <a href="/facts/U.S._Environmental_Protection_Agency/ghI985SI">U.S. Environmental Protection Agency</a> (EPA) in partnership with the <a href="/facts/U.S._Department_of_Energy/PRp6Cz8g">U.S. Department of Energy</a> (DOE). The EPA establishes energy efficiency specifications, and those that meet these specifications are eligible to display the ENERGY STAR logo. 
More than 75 product categories are eligible for the ENERGY STAR label, including appliances, electronics, lighting, heating and cooling systems, and commercial equipment such as food service products. In the United States, the ENERGY STAR label often appears with the <a href="/facts/EnergyGuide/hJPLDxMt">EnergyGuide</a> label of eligible appliances to highlight energy-efficient products and compare energy use and operating costs.
One of the most successful voluntary initiatives introduced by the U.S. government, the program has saved 5 trillion kilowatt-hours of electricity, more than <a href="/facts/US$/naEEDUhC">US$</a>500 billion in energy costs, and prevented 4 billion metric tons of greenhouse gas emissions.
Elements of the ENERGY STAR program are implemented in Canada, Japan, and Switzerland. In 2018, a 15-year long agreement with the <a href="/facts/European_Union/6GYcR8qM">European Union</a> expired. A previous agreement with the <a href="/facts/European_Free_Trade_Association/m8yeTInz">European Free Trade Association</a> also ended.
