Green Certificate

Green Certificate may also be known as a Renewable Energy Certificate (REC)

“A Green Certificate is a tradeable asset which proves that electricity has been generated by a renewable (green) energy source.” (

Owners of renewable generation have one REC for each megawatt of generation. They can keep or sell their certificates. REC purchasers can claim that the energy they used came from a renewable source. Such purchases support renewable power generation.

The EPA has a video on RECs at this link: RECs: Making Green Power Possible.
