Option 1: Emission Free Energy Certificates (EFECs)

Emission-Free Energy Certificates (EFECs) are created to represent the emission-free attributes of generating sources, such as nuclear, that do not directly emit greenhouse gases from combustion.  When you purchase Carbon-Free Electricity Plan from Constellation, the electricity you purchase will be matched with EFECs from nuclear energy sources allowing you to easily purchase carbon-free electricity.

Since EFECs come mostly from nuclear, it may not be a viable option if the sustainability requirements are against nuclear. EFEC’s are purchased the same way Certified Green E RECs (see below) are purchased, and is essentially an adder to the energy cost.
