The Department of Defense is one of the largest single consumers of energy and relies heavily on fossil fuels to meet national security objectives. The way energy is generated, transmitted, stored, and used, energy today is both a paramount combat enabler, and a potentially crippling vulnerability. History leads us to conclude that future wars will likely be fuel-limited environments. Critical infrastructure such as refineries, storage tanks, and distribution networks present lucrative targets to an adversary. Yet, the Air Force’s energy needs continue to grow. The reliance on fossil fuels lead to physical and geopolitical challenges in the security landscape, while alternative energy sources pose other challenges of their own. As the Air Force continues to reorient itself for great-power competition, the need to build more resilient energy infrastructure and supply chains has become increasingly urgent. The time has come to reimagine usage, generation, transportation, and storage of energy.
