Green Mountain Energy

Green Mountain was founded with the mission to change the way power is made.  Over a decade later, we remain 100% committed to this mission. From electricity products made using clean, renewable sources like wind to carbon offset products that help neutralize carbon emissions, every single product offered by our company has an environmental benefit. This makes Green Mountain the leading competitive retail electricity provider in the nation that's dedicated to cleaner energy – a distinction we're quite proud of!

Together with our customers, we've made a difference for the environment. Here's how:

Since our inception, our customers have helped avoid more than 14.8 billion pounds of carbon dioxide emissions. That's like:

  • Taking over 1 million cars off the road for a year
  • Over 624 million households turning off their lights for a week
  • Over 688 million trees would absorb in one year

All of our customers together have helped spur the development of over 50 new wind and solar facilities across the nation.

Our customers' demand for clean, renewable energy supports the Green Mountain Energy
