Pledge to change a light

"Change the World, Start with ENERGY STAR®" is a national campaign encouraging all Americans to join with millions of others and take small, individual steps that make a big difference in the fight against global warming.

Change the World

We really can Change the World by changing just one light bulb. If each household changed one standard bulb to one compact fluorescent bulb (CFL), we could: prevent 9 billion pounds of greenhouse gas emissions from power plants, the equivalent of taking 800,000 cars off the road; reduce garbage by keeping 110 million bulbs out of the trash; save enough energy to light more than 3 million homes for a year.

Now it’s your turn!

Join the more than 2.7 million individuals who have taken the ENERGY STAR® Pledge to save energy and help the environment.
