What is Green‑e® Energy?

Green‑e® Energy is the nation’s leading independent certification and verification program for renewable energy. It is a voluntary consumer-protection program that certifies superior renewable energy options offered by utilities and marketers in the voluntary renewable energy market. It is administered by Center for Resource Solutions, a nonprofit based in San Francisco, CA.

Why did the Center for Resource Solutions establish Green-e® Energy?

Green-e® Energy was established by the non-profit Center for Resource Solutions to provide information and an objective standard for consumers to compare renewable energy options, and to verify that consumers get what they pay for.

What does the Green-e® Energy logo mean to you?

When you see the Green-e® Energy logo, you can be assured that:
  • The renewable energy product contains only renewable resources,
  • The 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 option 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, and
  • 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.
