Renewable Energy Certificates
Renewable Energy Certificates (REC), or Green Tags, Green Certificates or Tradable Renewable Certificates represent the environmental attributes of the power produced from renewable energy projects and are sold separate from commodity electricity.[1]
Customers can buy the certificates whether or not they have access to green power through their local utility or a competitive electricity marketer, and they can purchase the certificates without having to switch electricity suppliers.
For every REC purchased, one megawatt-hour (MWh, or 1000 kilowatt-hours) of renewable electricity is generated and delivered to the power grid.[2]
Some renewable energy sources that can generate RECs are:[3]
- Solar hot water
- Photovoltaics (grid connect)
- Photovoltaics (stand-alone power supply systems)
- Wind
- Hydro

RECS International acts as the representative of market players towards national and European governmental authorities and facilitates all possible events and activities that enhance the RECS mission statement.[7]
