The Department of Defense U.S. has focused on developing and experimenting with renewable energy such as solar and wind power both at home and in combat zones, for example, Afghanistan.
The Army will invest in renewable energy development for military purposes, although it is expected that the resulting technology will end up having wide applications and civil consequences, as the army has such buying power that can create markets for itself.
The federal government intends to use the military as a testing and encouragement for green energy sector, while saving and improving its military potential.
It was last summer when the Pentagon released the Strategic Action Plan for Sustainability. The plan aims to meet the Obama Administration order that by 2020 at least 20% of the energy consumed comes from renewables. The Defense Department also appointed Sharon E. Burke as a director for plans and energy to guide the transition to energy efficiency and renewable energy.
Yet according to military sources, has not yet been any success with wind energy, shown impractical in the field of battle for the low estimate as possible for solar energy. Moreover, the wind usually occurs at the top of the mountains, where troops would be exposed.
The new military initiatives are explained in part by the hundreds of thousands of vehicles that the American army has deployed around the world.
Increasingly heavier vehicles to be resistant to some increasingly destructive weapons, and therefore need more fuel. A fuel that is often boycotted their supply, so that energy efficiency would strengthen the power and independence of the army.
