About Green Mountain Energy

As the longest-serving renewable energy retailer in the United States, we want to help make the planet a cleaner, greener place to live.

Our mission

"Choose wisely. It's a small planet.®" That's how it all started back in 1997 when a crew of like-minded folks in Vermont set out on a mission: to inspire hope and motivate action through the use of clean energy. Over 25 years later, we’re proud to be a carbon-neutral company that continues to keep sustainability at the heart of everything we do. 

Our business

Green Mountain Energy proudly brings you 100% clean energy. Our solutions are backed by the purchase of renewable energy certificates (RECs) for homes, small businesses and anyone else looking to get involved with sustainability efforts.
