In this letter to The Atlantic Monthly in response to an article by Robert Bryce, Amory Lovins discusses the American military’s fuel costs during the Iraq War between 2003 and 2005. Lovins argues that a solution to the high cost of fuel for military operations is highly energy efficient military vehicles. He points out that the military could cost-effectively save two-thirds of their fuel directly, plus more fuel to deliver platforms and fuel. Such fuel efficiency would save many lives, billions of dollars a year in fuel cost, and perhaps ten times that in logistics cost, while making war-fighting more capable and ultimately less necessary. This document also includes a response from Robert Bryce, as well as an exchange between him and Capt. David J. Morris (USMC).
