When the world’s largest military decides to power their massive fleet of vehicle on more eco-friendly fuel, that’s a good thing, right? Not according to the US Congress. In fact, the defense budget pretty much bans biofuels or any alternative fuel that costs more than oil-based diesel and petroleum. Not surprisingly, the congressman that presented the amendment was from one of America’s largest oil-producing states: Texas. The Defense Department argues that it needs to come up with alternative sources of energy that do not involve changing over current fuel tanks. The Obama administration shares this vision, which is probably the reason that the Republican-controlled Congress is getting in the way of the military’s green initiative.
