A new PNNL study shows that 17 percent of the United States’ imported oil for transportation could be replaced by biofuel made from algae grown in outdoor raceway ponds located in the Gulf Coast, the Southeastern Seaboard and the Great Lakes. This June 2010 photo shows raceway ponds in Southern California and was taken by the QuickBird satellite.
