Green Energy DC is a single resource for all you need to know about energy efficiency and renewable energy programs, products and services in the District of Columbia. The Clean and Affordable Energy Act of 2008 (CAEA) requires the Mayor, through DDOE, to contract with a private entity to conduct sustainable energy programs on behalf of the District of Columbia. The CAEA authorizes the creation of a Sustainable Energy Utility (SEU) and designates the SEU to be the one-stop resource for energy efficiency and renewable energy services for District residents and businesses.  The SEU will serve under a performance-based contract with DDOE, with input and recommendations from the SEU Advisory Board, and oversight from the Council of the District of Columbia.
