Renewable Energy Certificates (RECs) were created by the Environmental Protection Agency (EPA) to help the development of renewable energy generation sources. Each REC represents the generation of one megawatt (or 1,000 kilowatts) of clean electricity produced from a renewable energy source. The "environment attributes" include the reduction or avoidance of Carbon Dioxide (CO2) emissions resulting from conventional fossil fuel-based electricity generation. As the owner of a REC, you can claim to have purchased clean renewable energy and helped reduce your carbon footprint. Doesn't that sound great? When you purchase a REC through Clean Nation, you are taking part in a subscription-based program where you receive one clean energy REC each month. You'll receive a unique identifying number for each certificate which designates you have purchased a one-megawatt clean energy commodity.
