Change a Light, Change the World
Join our effort to save energy and help reduce greenhouse gas emissions. Pledge to switch at least one incandescent bulb in your home with an ENERGY STAR® qualified bulb.
If every American home replaced just one light bulb with an ENERGY STAR compact fluorescent light (CFL) bulb, we would save enough energy to light more than 3 million homes for a year and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars.
What’s more, changing to an ENERGY STAR qualified CFL can save you up to $42 in electricity costs over the life of each bulb.
Take the ENERGY STAR pledge now and help change the world.
