ENERGY STAR is the simple choice for energy efficiency achievements. People across America have looked to the EPA's ENERGY STAR program for guidance on how to save energy, save money, and protect the environment. Behind each blue label is a product, building, or home that is independently certified to use less energy and cause fewer of the emissions that contribute to climate change. Today, ENERGY STAR, is the most widely recognized symbol for energy efficiency in the world, helping families and businesses save $24 billion in 2012 alone. For more information go to energystar.gov.
