History of Energy Star in Timeline

Energy Star is a program run by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) to promote energy efficiency. Products meeting specific EPA energy-efficiency criteria can display the ENERGY STAR logo. This helps consumers easily identify and purchase energy-saving products, reducing energy consumption and contributing to environmental protection.
