WASHINGTON, Nov. 3 (UPI) -- The U.S. Navy aims to use alternative energy to meet 50 percent of its needs within the next 10 years, an environmental official said in Washington.
U.S. Navy Rear Adm. Philip Cullom, a director of environmental readiness for the force, said the Navy was testing a command boat that used a 50-50 blend of algae-based fuel and conventional petroleum as part of a green-energy campaign.
