A high Energy Star rating indicates that a product, such as an appliance or building, meets strict energy efficiency guidelines set by the U.S. Environmental Protection Agency. This rating helps consumers identify items that use less energy, which can lead to lower utility bills and reduced environmental impact. Products with a high Energy Star rating are tested and certified to perform efficiently without sacrificing quality or performance. This rating applies to various categories, including refrigerators, heating and cooling systems, and lighting, making it easier for consumers to make informed choices that contribute to energy conservation.
