In 2009, the Commandant of the Marine Corps (CMC) created the USMC Expeditionary Energy Office (E2O) to

“analyze, develop, and direct the Marine Corps’ energy strategy in order to optimize expeditionary capabilities across all warfighting functions.”

E2O works closely with the combat and technology development communities and serves as the proponent for Expeditionary Energy in the force development process. Additionally, E2O is tasked with advising the Marine Requirements Oversight Council on all energy and resource-related requirements, acquisitions, and programmatic decisions. And, in accordance with the National Defense Authorization Act for Fiscal Year 2009, the Secretary of the Navy assigned the E2O responsibilities as the Marine Corps Senior Official for Operational Energy.
