Army must cut energy costs to balance budget

The Army must reduce energy costs at its installations and on the battlefield to meet the challenges of a Defense Department budget that will shrink $487 billion during the next decade, Gen. Raymond Odierno, the service's chief of staff, told a Pentagon press briefing Friday.

Odierno did not provide details, but in August 2011 the Army launched a program to seek $7.1 billion in private investments for renewable energy plants on its installations, with the goal of those plants producing more energy than they consume. The surplus, generated by solar, wind or geothermal plants, would be sold on the open market.

The Army also must cut its use of fuel on the battlefield, and BAE Systems has proposed a Toyota Prius approach toward developing the new $7.6 billion ground combat vehicle, which would feature a hybrid electric drive and a battery pack to supplement its diesel engine.
