To carry out military and humanitarian missions around the world, U.S. forces require reliable fuel supplies and secure supply lines. At the micro level, the military is as much at the mercy of high oil and gasoline prices as the average consumer. In addition, when you calculate the fully burdened cost of fuels, for instance a gallon of jet fuel delivered to the front lines in Afghanistan, it can be upwards of $400 per gallon. And, on a macro level, oil often comes from regions of the world that are not U.S. military allies. The need for great energy independence is therefore a very important national security issue.
