WHAT IS A RENEWABLE ENERGY CERTIFICATE (REC)?
When a source of renewable energy, like a wind or solar farm, generates 1,000 kWh of electricity (about the average monthly electricity use in a typical US household), a Renewable Energy Certificate (REC) is issued.
“Each certificate represents a given amount of electricity that’s been generated from renewable sources,” Eduardo Garcia wrote in The New York Times. “When energy companies produce that power, they get certificates they can sell to consumers.”
