As a carbon-neutral energy retailer, it’s important to us that our products are sourced from high-quality projects and undergo a voluntary third-party audit annually. These high standards, combined with more than 25 years of experience in cleaner energy, mean that you can be confident in the cleaner energy and carbon offsets you buy from Green Mountain Energy.

We offer clean electricity solutions to customers across a variety of markets in the United States. You can also learn about some of the renewable energy and carbon offset projects we’ve supported over the years, thanks to our customers’ demand and the Green Mountain Energy Sun Club projects we’ve donated to nonprofits.
