What is Renewable Energy Certificate (REC)?

Renewable Energy Certificate

Quick Answer

A Renewable Energy Certificate (REC) is a tradable certificate that represents proof that one megawatt-hour of renewable energy has been generated. It helps track and promote the use of renewable energy sources like wind and solar power.

Overview

A Renewable Energy Certificate (REC) is a way to certify that energy has been produced from renewable sources, such as solar or wind. Each certificate represents one megawatt-hour of renewable energy generated. When a renewable energy producer generates electricity, they earn RECs, which can then be sold to companies or individuals looking to offset their carbon footprint or support green energy initiatives. The process works by allowing renewable energy producers to sell their RECs separately from the electricity they generate. This means that even if a company does not directly use renewable energy, it can buy RECs to claim that it is supporting renewable energy production. For example, a company that uses fossil fuels can purchase RECs to demonstrate its commitment to sustainability and to help fund renewable energy projects. RECs matter because they provide a financial incentive for the development of renewable energy sources. By purchasing RECs, businesses and individuals can help increase the demand for clean energy, which can lead to more investment in renewable technologies. This not only helps reduce greenhouse gas emissions but also promotes energy independence and job creation in the renewable energy sector.
