Calif. farmers team up to convert beets to ethanol - Article Photos 1/3

In this March 6, 2013 photo, a mature sugar beet is shown, in Tranquility, Calif. Farmers in central California hope to build the nation's first commercial-scale bio-refinery in nearby Mendota, Calif., to turn beets into biofuel. Europe already has more than a dozen such plants, but most ethanol in the United States is made from corn. (AP Photo/Gosia Wozniacka)
