Green Mountain Energy1




Green Mountain, the nation’s leading competitive retail provider of cleaner energy and carbon offset solutions, was founded in 1997 with the mission “to change the way power is made”. Over a decade later, the company remains 100% committed to this mission. From electricity products made using clean, renewable sources such as wind to carbon offset products that help neutralize carbon emissions, every single product offered by Green Mountain Energy has an environmental benefit.

The company is the longest serving green power marketer in the United States, backed by one of the largest renewable power producers, and the only retail electricity provider in the nation that’s dedicated to cleaner energy.

Green Mountain has made a significant difference for the environment; since inception, Green Mountain and their customers have helped spur the development of over 40 new wind and solar facilities across the nation and avoid more than 11.3 billion pounds of carbon dioxide emissions.

That’s as much as:


  • Taking over 52 million cars off the road for a week.
  • Over 473 million households turning off their lights for a week.
  • Over 478 million trees would absorb in one year.


Green Mountain are proud of their membership on The Green Power Partnership which is a voluntary program that encourages organizations to buy Green Power as a way to reduce the environmental impacts associated with purchased electricity use. The Partnership currently has nearly 1,300 Partner organizations voluntarily purchasing billions of kilowatt-hours of green power annually.

Partners include a wide variety of leading organizations such as Fortune 500 companies, small and medium sized businesses, local, state and federal governments, and colleges and universities. (for information, please visit
