## Highlights

The Department of Defense (DOD) relies heavily on petroleum-based fuel for mobility energy--the energy required for moving and sustaining its forces and weapons platforms for military operations. Dependence on foreign oil, projected increases in worldwide demand, and rising oil costs, as well as the significant logistics burden associated with moving fuel on the battlefield, will likely require DOD to address its mobility energy demand. GAO was asked to (1) identify key efforts under way to reduce mobility energy demand and (2) assess the extent to which DOD has established an overarching organizational framework to guide and oversee these efforts. GAO reviewed DOD documents, policies, and studies, and interviewed agency officials.
