Renewable Energy Certificates

What are RECs?

A renewable energy certificate (REC) legally conveys the environmental attributes of 1 megawatt-hour (MWh) of electricity generated from a renewable energy source (e.g., solar, wind, biomass, hydro). RECs are used to track renewable energy from the point of generation to a purchaser of green power. The one purchaser owns exclusive rights to claim all renewable generation attributes of the REC. To safeguard this exclusivity, RECs are tracked in one of 10 electronic tracking systems across Canada and the United States.

RECs: Making Green Power Possible

RECs are a flexible tool to help any organization – no matter its limitations – achieve stated environmental and sustainability goals. RECs represent the environmental attributes of 1 megawatt-hour (MWh) of electricity generated from a renewable energy source (e.g., solar, wind, biomass, hydro), and are used to track renewable energy from the point of generation to a purchaser of green power. The electricity purchased from renewable sources displaces electricity on the grid that would have otherwise been produced from traditional generating facilities.
You may have heard comparisons of RECs to carbon offsets. Although they both are needed for green power, and both represent the environmental benefits of certain actions that can help mitigate greenhouse gas emissions, they are fundamentally different instruments. Offsets represent a metric ton of emissions avoided or reduced; RECs represent attributes of 1 MWh of renewable electricity generated. You don’t offset your usage with a REC, but rather, match your usage with RECs.
Green-e® certified renewable energy and carbon offset products meet the most stringent environmental and consumer protection standards in North America. Green-e Energy is the trusted global leader in voluntary clean energy certification for renewable energy and carbon offsets. Businesses looking to purchase verified clean energy with confidence should choose Green-e certified sustainable products and services, backed by the economic and environmental benefits of clean energy policy, markets and technology to reduce the environmental impact of their electricity use. The Center for Resource Solutions (CRS) runs multiple programs that certify RECs as Green-e certified. It is a nonprofit resource, advocating for the advancement of clean energy policy, markets and technology, and believing in their economic and environmental benefits.
