Energy Offerings

Green Mountain Sustainability Efforts

Since the start, Green Mountain has been dedicated to its mission: to inspire hope and motivate action through the use of clean energy. Since 2002 they have tracked carbon dioxide (CO2) emissions avoided by folks buying our products or signing up for our plans.

This effort is no small feat and involves giving an independent auditor full access to their books, diligently investing hundreds of hours to responsibly track and manage REC supply to ensure it is appropriately allocated all so that customers can see the emissions-free benefits they are getting when they enroll.

In an effort to further support their mission Green Mountain examines their own business impact to be sure they can be a more eco-focused company. These small, but mindful changes to their daily business operations has allowed them to offset 100% of their corporate carbon footprint since 2002.

Green Mountain Energy Sun Club

Green Mountain Energy’s Sun Club champions environmental stewardship and sustainability by supporting nonprofits dedicated to renewable energy and conservation. The Sun Club has donated millions to projects that advance green energy technologies and promote energy efficiency.

Green Mountain Renewable Energy Plans

All Green Mountain Energy plans are sourced from 100% renewable energy including wind and solar. A renewable electricity plan essentially ensures that no matter how much electricity you use, an equal amount of renewable electricity will go into the grid. It does not mean that all the electricity you use is now renewable. This is because there's no way to route renewable energy once it enters the electric grid. It gets jumbled up with the rest of the electricity from all other sources.

To keep track of the renewable energy that enters the grid, we use renewable energy credits (RECs). These credits are generated once one full megawatt of renewable electricity enters the grid. The generator can then sell that REC to someone who wants to purchase renewable electricity. When you procure a renewable energy plan, your provider purchases these RECs on your behalf.
