Energy Attribute Certificates (EACs) serve as a tracking system for energy produced from renewable sources, like wind or solar power. Each certificate represents the environmental benefits associated with the generation of a specific quantity of renewable energy, usually one megawatt-hour (MWh). EACs can be bought and sold in various markets, allowing entities to claim that they have used renewable energy without necessarily having to consume it directly. This mechanism supports compliance with regulatory frameworks and promotes the use of renewable energy sources by providing monetary incentives.
