Army Fuel Consumption


Army Fuel Consumption

 
     The Army runs of fossil fuels, and on average the DoD as a whole can consume as much fuel as a small country. The heavy reliance on fuels has grown greater as vehicles have become heavier, and electronics in the war zone have become integral to the nation’s ability to fight. The following short article will highlight an area where the Army uses the most fuel; ground vehicles, and where it is attempting to save fuel; generators. Oil derived fuels accounts for around 80% of DoDs yearly energy consumption.

     As wars have continued to be fought, the modes of transportation have changed from Personal Leather Carriers (Feet), to carts drawn by horses, trucks, and now APCs, MRAPs, and helicopters. As vehicles have gotten bigger and armor has been added, fuel consumption has also gone up to meet the power demands required to move them. At the same time, a highly digitalized battlefield requires that bases use large amounts of fuel to provide the necessary electricity for electronics. All of this has resulted in a rise in the fuel consumption of the Army, and other branches of service. On average, total DoD fuel consumption is around $13.3 billion dollars for around 932 trillion Btu. That is about the same amount of energy that Nigeria uses each year. That is a lot of energy.
As heavier vehicles have been added to the Army inventory, more fuel as been required to operate them. The HMMWC has a fuel economy of about 14 mpg. An MRAP, which is being used to supplement and replace HMMWVs in certain situations, has no base model to compare but on average has a fuel economy around 3 mpg. That’s over four and a half times worse than an unarmored HMMWV; with armor added the fuel economy of the HMMWV drops dramatically. The added armor and protection afforded by the MRAP is great on the battlefield, but hell for the logistical side of war fighting.

     FOBs and major bases in Afghanistan utilize large numbers of small generators. These generators are used from providing power to recharge radio batteries, to powering computer and communications systems, to providing energy to cook the food, provide warm water to shower with, and to power the various devices used for surveillance and base protection. When fuel runs out, generators of lower priority (such as those used for non-mission essential items) will be switched off so that communications generators will be kept running until more fuel arrives. In order to help reduce the amount of fuel consumed now and save money in these financially tight times, new technologies are being used to reduce the amount of fuel used at FOBs and bases in Afghanistan. The Army began fielding a new generation of generators that promise to consume 21% less fuel than the current fleet of generators, and also claim to be 95% more reliable. This reduction across the board of generators can have great impacts on the Army’s fuel consumption, as these generators require less fuel more can be made available to the vehicles that go out on patrol each day.

     These new generators will promise to reduce the logistical foot print in Afghanistan as less fuel is required for their continued operation. This will reduce the amount of fuel consumed by smaller bases, which in turn will reduce the number of trips by ground vehicle or airplane to provide supplies.

     Overall with the large amount of fuel being used throughout Afghanistan, the Army has to rely on ground transportation for areas with decent infrastructure, and airplane resupplies to regions with inadequate roads. The first method requires the use of a fleet of vehicles like the one pictured above (image 1) to transport the fuel. They require their own fuel to get to their destination, protection against attacks, and time to get where they need to go. The Army’s heavy use of oil and other forms of energy may prove to be a bigger problem down the line as money becomes stricter, oil prices fluctuate to extremes, and as fuel and energy requirements increase as vehicles continue to become bigger and heavier, and as more of the battlefield becomes electronic. If the Army can continue to incorporate new technologies such as the new generators and possible new domestic sources of fuel, it can cut costs and divert more resources to R&D for future operations.

  1. The army uses too much fuel right now. i do not know the practicallity of adding something like solar panels on the tops of trucks or bunkers etc to help augment power or if this would only add to the costs. Fuel is however much more efficient than horses and oxen etc and we will continue to rely on it for many years until something else comes along and then that will eventually be replaced...

  2. Generators are the single pieces of equipment that use the most amount of fuel since they are on all the time and power everything at the FOBs. The main problem with implementing solar panels at a FOB are the fact that they are very fragile. Any sort of bullet or explosion will completely destroy the panel. These panel are extremely expensive and if the military were to use them there would be alot of up front cost in regards to purchasing them and installing the equipment. The military would not begin to see monetary savings for a while. The smarter idea would be to use renewable fuels or implement engines that are more fuel efficient. If only generators could be outfitted with hybrid engines...
