About the
Company
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 use the power of consumer choice and help change the way power is made. Over 20 years later, we’re proud to be a carbon-neutral company that continues to keep sustainability at the heart of everything we do. Join us as we help make the planet a cleaner, greener place to be.
Our business
As the longest-serving renewable energy retailer, we’re proud to bring you 100% clean energy solutions, backed by the purchase of renewable energy certificates (RECs), for homes, small businesses and anyone else looking to get involved with sustainability efforts.
Our impact
Thanks to customer demand, we're able to support sustainable projects in the markets we serve. Our products are sourced from high-quality projects and undergo a voluntary third-party audit annually.
