When you enroll in Clean Wind, Green Source or Green Future Solar you purchase renewable energy certificates (RECs). A REC is created when a megawatt-hour of renewable energy is produced and delivered to the grid. RECs increase demand for, and drive development of, more renewable energy sources.

All RECs purchased on behalf of Clean Wind, Green Source and Green Future Solar customers are verified and certified by Green-e Energy national standards, the nation’s leading independent consumer protection program for the retail sale of renewable energy.

  • The renewable certificates are not sold more than once or claimed by more than one party.
