 The Secretary of the Navy, Ray Mabus, spoke at Boston Navy Week about the importance of the Great Green Fleet's demonstration in this year's Room of the Pacific or RIMPAC exercise. The carrier and the submarine will be running on nuclear power, but everything else, the aircraft, the surface combatants, will be on a 50-50 blend of regular aviation gas or diesel and biofuel. The demonstration is intended to evaluate the performance of drop-in replacement biofuel blends, which is made from used cooking oil and algae and certain energy-efficient technologies. Secretary Mabus went on to talk about why the Navy is using biofuels and leading the charge for America to reduce the dependency on foreign oil. Even if we could get all the oil and gas we needed in America, it's still a global commodity, and the price shocks when somebody threatens to close the straits of our moves are when Libya started. Every time the price of a barrel of oil goes up a dollar, it costs the Navy 31 million dollars in additional fuel costs. So we've got to correct that, and we're moving to do so. Approximately 450,000 gallons of 100% neat biofuel was purchased for the Great Green Fleet demonstration, which includes USS Nimitz and carrier Erwing-11, USS Princeton, USS Chaffee, USS Chunghoon, and USNS Henry J. Kaiser. The Great Green Fleet is scheduled to deploy in 2016. For more information about the Navy's energy programs, visit greenfleet.dodlive.mil-home.
