DoD Energy Use in 2010
DoD spent $15.2 billion on energy in (Fiscal Year) 2010. Seventy four percent of this (or $11.2 billion) can be attributed to operations while the remaining 24% (or $3.7 billion) to the Department’s permanent installations and 2% (or $0.3 billion) to non-tactical vehicles.
Note that 872 trillion Btu corresponds to site delivered energy. In energy balance terminology it refers to final energy consumption. So, if you want to compare this amount with a country’s energy consumption you better use the estimated source energy, which by the way more or less corresponds to primary energy supply, and which by way is not given in the DoD’s annual energy management report.
According to my calculations the DoD’s primary energy consumption is slightly above 1100 trillion Btu. This is roughly the amount of energy consumed in Nigeria, a country with a population of 150 million.
Two types of energy are dominant in DoD’s energy mix - oil, with a share of 77% , and electricity, with a share of 12%.
This should be not surprising because:
(1) The DOD’s worldwide infrastructure includes over 539,000 facilities (300,638 buildings and the rest structures) located at more than 5,000 sites around the world, on more than 113,000 km2 (bigger than the land area of Louisiana).
(2) The DOD operates approximately 15,800 aircraft, over 300 non-nuclear ships, some 195,000 non-tactical fleet vehicles, over 300,000 tactical ground vehicles (wheeled and tracked), in addition to over 120,000 generators. And all these machines consume oil, lots of it.
· First, DoD’s annual energy management reporting system considers only purchased energy. Therefore, if DoD doesn’t pay anything (in kind fuel and power) then it is not counted.
· Second, the DoD does not take into account of nuclear energy in its energy accounting. So, nuclear energy consumed in 11 nuclear aircraft carriers and over 70 nuclear submarines are unaccounted for.
This is my message for William Lynn (Deputy Secretary of Defense) and Sharon Burke (Assistant Secretary of Defense for Operational Energy Plans and Programs).
Without having a comprehensive data there is no way to do any meaningful energy analysis. Mrs Burke rightly mentioned on several occasions that the DOD lacks sufficient data on and analysis of operational energy use to manage consumption effectively. The DOD needs better statistics on how much energy is being consumed, where, and for what purposes.
