REC's

Renewable Energy Certificates (REC's) are issued when a wind farm or solar farm or a home owner produces one megawatt-hour (MWh) of electricity so one REC is earned for each MWh. That REC can now be sold at the current market price. Companies will buy these REC's to meet their renewable goals. Amazon for example can purchase these and then say they are 100 % renewable even though the are still getting power from fossil fuel plants. The same is true for other industries.
