SAN DIEGO, Calif. (AP) — The U.S. Navy is conducting its largest demonstration yet of the use of biofuel to power a ship.

The Paul F. Foster has been filled with about 20,000 gallons of a blend of algal oil and petroleum. The ship will leave Point Loma in San Diego on Wednesday night for an overnight journey to Port Hueneme.

The Navy has been looking at the algae-based biofuel to run its ships. The initiative is part of an effort to become a leader in green energy, with branches of the armed services aiming to cut fossil fuel consumption by as much as 50 percent by 2020.

The military uses more than 90 percent of the energy consumed by the federal government.

Fuels made from algae oil burn cleaner than fossil fuels and require no drilling to produce.
