Future energy efficiency improvements within the US department of defense: Incentives and barriers

The present work describes the military impact of improved efficiency and then highlights existing technological, political, and financial barriers for improving overall energy efficiency. As the largest user of energy within the US government, the Department of Defense (DOD) is rightly concerned that any disruption to the nation's energy supply may have an extremely adverse impact on its military capabilities. The total solution to providing energy security will be multi-faceted with progress required on many fronts. Increasing the use of renewable energy sources and improving energy storage capabilities are gradually creating a positive impact, but investing in improving the overall efficiency of the military effort provides both immediate and long-lasting payback. One might suppose that a decrease in the energy used by the DOD should lead to a decrease in military capability, but historical data proves otherwise. It is shown that the military has additional impetus, compared to civilian consumers, to pursue energy-efficiency improvements. Many tools are available to help the DOD along this path, yet there remain obstacles which must first be identified and analyzed as discussed herein.
