The USMC Expeditionary Energy Office (E2O) is at the forefront of transforming how the Marine Corps generates, manages, and utilizes energy in expeditionary environments. Established on October 1, 2009, by direction of the Commandant of the Marine Corps (CMC), the E2O was born out of a commitment to prioritizing energy as a critical enabler for warfighting effectiveness.
Driven by the need to optimize expeditionary capabilities across all warfighting functions, the E2O's core mission is to analyze, develop, and direct the Marine Corps’ energy strategy. Our efforts are guided by the Commandant’s Planning Guidance, Force Design 2030, and other emerging warfighting concepts that define the future of Marine Corps operations. We are the Functional Advocate for Operational Energy, providing expert advice to the Marine Requirements Oversight Council (MROC) on all energy and resource-related requirements, acquisitions, and programmatic decisions. Our work is critical to enabling the USMC to meet the energy mandates outlined in Title 10 U.S.C. § 2926, legislation governing the management of energy for contingency operations.
Originally a special staff under the Assistant Commandant of the Marine Corps, the E2O's current placement under Deputy Commandant Combat Development and Integration (CD&I) underscores our strategic role in shaping the future of Marine Corps warfighting. This placement ensures that energy considerations are seamlessly integrated into the development of new concepts, doctrine, and operational capabilities, from initial requirements to final acquisition.
We are dedicated to:
-
Reducing Dependence on Bulk Fuel: Minimizing the vulnerability of our forces by decreasing reliance on fuel supply chains.
-
Promoting Energy Efficiency: Implementing energy-saving technologies and practices to minimize operational footprint and extend operational reach.
-
Advancing Alternative Energy: Identifying, testing, and integrating innovative energy solutions to enhance energy security and reduce logistical burdens.
At the E2O, we believe that energy is not just a resource, it is a strategic advantage that enables the warfighter to fight our nation's battles across the spectrum of conflict, ensuring we are postured to fight tonight , and prepared to win tomorrow's fight.
Our Functional Areas:
To achieve our mission, the E2O focuses its efforts across four key functional areas:
-
Power Generation, Distribution, and Storage: Develops technology that produces, distributes, or stores energy outside of bulk fuel. This includes generators, photovoltaics, fuel cells, advanced batteries, electrical power distribution systems, and vehicle power exportation, supporting both universal energy needs and specific platforms (UXVs, sensors, DEWs, medical equipment, etc.).
-
Bulk Fuel: Focuses on research and development efforts to increase efficiency and performance of bulk fuel storage and distribution, including modernizing existing systems.
-
Modeling and Simulation: Develops software and equipment that analyze and project energy consumption for Marine Corps units for planning and acquisition.
-
Training and Education: Develops training and education programs that increase the efficiency and effectiveness of energy-centric FMF activities. These programs support E2O efforts by defining required training for new technology and promoting a warfighter mindset that values and conserves energy.
