Energy Harbor is committed to a carbon-free future. We are one of the largest generators of clean, reliable carbon-free electricity in the country. Working together, we can make a difference. Energy Harbor is striving to do our part.

Energy Harbor provides residences and businesses with clean energy options that are both simple and affordable, with Emission Free Energy Certificates (EFECs). Why should you consider Energy Harbor Emission Free Energy Certificates?

Power your home or business with Emission Free Energy Certificates

The majority of our Emission Free Energy Credits (EFECs) come from one of our four nuclear generation units located in Ohio and Pennsylvania, which are capable of generating more than thirty million EFEC’s annually.    


Nuclear energy provides more than 55 percent of carbon-free electricity in the United States and The International Panel on Climate Change found that nuclear energy’s life cycle carbon emissions were lower than solar, geothermal and hydropower and comparable to wind-generated power. According to The International Panel on Climate Change, nuclear energy is as clean as renewable energy. Electricity generated with nuclear energy avoids the emissions of more than 528 million metric tons of carbon dioxide every year. That’s more than the emissions from 111 million passenger vehicles—all of the passenger vehicles on the road in the U.S. 

Carbon-free nuclear generation is the most dependable source of electricity, operating 24/7 at more than 92 percent average capacity factor. (Capacity factor is the ratio of the actual amount of electricity generated by a plant compared to the maximum amount that it could potentially generate.) That’s more than two times the capacity factor of any other clean source. Nuclear plants are capable of operating for 18-24 months without interruption.
