Founded in 1997, Green Mountain Energy has established itself as one of the most well-known and trusted names in sustainable energy, providing eco-conscious consumers an alternative to traditional fossil fuel-based electricity.
Unlike conventional electricity providers, Green Mountain exclusively offers plans sourced from wind and solar energy. By choosing Green Mountain Energy, customers can reduce their carbon footprint and support the growth of renewable energy infrastructure. The company purchases electricity from wind and solar farms.

While Green Mountain Energy is known for its renewable energy offerings and excellent customer service, it’s also known for its high price tag. Despite that, the provider earned a near-perfect 4.9 out of 5 stars in our review, with perfect 5-star scores in customer service and satisfaction.
