According to Edward Thomas Morehouse Jr., principal deputy assistant secretary of defense for operational energy plans and programs, the U.S. Department of Defense estimates that it will use about 96 million barrels of fuel at a cost of nearly $15 billion in fiscal year 2015. DoD plans to invest $1.7 billion to improve how energy is used for military operations, and about $9 billion across the Five-year Defense Plan. The 92% of the investment will be used to enhance energy performance of weapons and military forces, and another 7% will be used to diversify and secure supplies of operational energy. Morehouse also highlighted the level of progress DoD has achieved in the realm of energy, stating "With energy and energy logistics now being incorporated into major war games, and as a mandatory performance parameter in our requirements development process,...understanding how energy affects our operations is becoming more deeply understood."
