Green-e® Certification

Green-E Certification

Green-e® Energy offered by the Center for Resource Solutions, is the most stringent and widely-used voluntary certification program in the U.S. setting buyer protection and environmental standards for renewable energy credit (REC) products. The Green-e® Energy certification ensures that only one customer claims credit for each REC and the megawatt-hour of electricity generation it represents.

About Renewable Energy Credits

RECs are created when a renewable energy facility generates electricity. One REC is equivalent to 1,000 kilowatt-hours of renewable electricity and represents the environmental benefits associated with the generation of that energy. Think of a REC as a receipt — it allows businesses, governments, or individuals who can’t generate renewable electricity to purchase, track and verify their green power purchase.

Green-E LogoWhat the Logo Means

When you see the Green-e® Energy logo, it means:

  • The renewable energy option contains only new renewable resources.
  • The renewable sources of energy supplying the renewable energy option are independently verified by Green-e® Energy, operated by the non-profit Center for Resource Solutions.
  • The purchaser of a Green-e® Energy Certified renewable energy certificate is the sole "owner" of the environmental attributes of a specific megawatt hour (MWh) of energy added to the grid. Independent verification ensures that no MWh are double-counted.
  • The company offering the certified renewable energy option agrees to abide by the Green-e® Energy Code of Conduct and Customer Disclosure Requirements governing its ethical treatment of customers.
