Ace the LEED Green Associate Exam 2026 – Go Green, Go Great!

Renewable Energy Certificates (RECs) represent proof that 1 kilowatt-hour (kWh) of electricity was generated from a renewable source, such as solar, wind, or hydroelectric power. Each REC serves as a tradable commodity that verifies the generation of renewable electricity, allowing businesses and individuals to support clean energy. By purchasing RECs, organizations can claim to be utilizing renewable energy, even if the physical electricity consumed is from other sources.

The other options do not accurately reflect the function of RECs. For instance, proof of air quality compliance pertains to emissions and pollutants, which is unrelated to the generation of renewable energy itself. Similarly, government approval for energy projects involves regulatory processes and is not the purpose of RECs. Lastly, a certificate of good practice for energy providers does not specifically address the renewable energy generation aspect that RECs focus on.
