Per retired brigadier general Steven Anderson, who did logistics for Petraeus in Iraq: * https://www.npr.org/2011/06/25/137414737/among-the-costs-of-war-20b-in-air-conditioning https://www.npr.org/2011/06/25/137414737/among-the-costs-of-... The DoD position: > 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. On Anderson (at the time): > Anderson advocates for increased energy efficiency for military structures in order to cut down on the need for long, dangerous fuel-transport missions. […] Anderson says experiments with polyurethane foam insulation for tents in Iraq cut energy use by 92 percent and took 11,000 fuel trucks off the road. […] > In February 2011 Gen. Anderson has joined the Relyant corporation as Senior Vice President, in charge for the company’s presence in Washington, D.C., managing the organization’s strategic planning and military business development. Relyant is a global provider of construction and insulation projects, life support, demining, logistics/procurement, security, and IT communications. It should be noted though that these additional costs are spent regardless of the volume of supplies sent over supply lines, as the convoys do not carry only fuel, but also food, ammunition, batteries, spare parts, building supplies etc. nevertheless, a green approach could significantly reduce volume, and costs and risk of such operations. * https://defense-update.com/20110627_costly_aircondition.html https://defense-update.com/20110627_costly_aircondition.html
