evidence: The amount the U.S. military spends annually on air conditioning in Iraq and Afghanistan: $20.2 billion, according to a former Pentagon official. [...] "And anyway, it's not the war that's broken Washington's piggy bank," he adds, noting that Medicare, Medicaid and Social Security account for far more spending than the $107 billion the Pentagon says it will spend in Afghanistan next year. [...] CLARIFICATION: The Pentagon disputes the calculation made by Anderson about air conditioning costs. Defense Department spokesman Dave Lapan says that in fiscal year 2010, the Pentagon spent approximately $15 billion on energy for all military operations around the world. The Pentagon says when it comes to Afghanistan, it spent $1.5 billion from October 2010 to May 2011 on fuel. That fuel was used for heating and air conditioning systems, but also for aircraft, unmanned aerial systems, combat vehicles, computers and electricity inside military structures.
