What is Change a Light?
The ENERGY STAR® Change a Light, Change the World Campaign is a national challenge to encourage every American to help change the world, one light — one step — at a time. At the campaign’s heart is the ENERGY STAR Change a Light Pledge, found at energystar.gov/changealight.
This online Pledge is a simple but vital method of forming a community of inspired individuals across the nation to commit to reduce greenhouse gases and save energy. The goal is to encourage at least 500,000 individuals to take the ENERGY STAR Change a Light Pledge this year. People who took the ENERGY STAR Change a Light pledge online last year will save more than $2 million worth of energy and reduce more than 33 million pounds of greenhouse gas emissions.
Every light changed is a step in the right direction to preserve energy resources and our environment for this generation and the next.
