  2. Farmers Plant Corn As Ethanol Demand Keeps Prices High

    ROCHELLE, IL - MAY 8: Corn from test plots sits in the barn on the farm of seed dealer and farmer Erik Petry May 8, 2007 near Rochelle, Illinois. More acres in the United States are expected to be planted with corn this year than any year since WWII to help meet increased demand, driven in part by increased ethanol production.

    A peasant cuts sugar cane during harvest in Usina Bonfim in Guariba, 400 km from Sao Paulo, on June 6, 2008. While other countries are hiking prices at the pump, Brazil is going against the trend: maintaining retail prices by cutting fuel taxes. Ethanol, made from domestically-grown sugar cane, is cheaper than gasoline, and sells for just 1.5 reals (0.95 cents) per liter -- giving the country an added measure of insulation from global oil prices. More than 80 percent of cars are "flex-fuel" models, meaning their engines are built to run on either gasoline or ethanol, or a mix of the two.

  4. A selection of General Motors flexfuel vehicles

    A selection of General Motors flexfuel vehicles that can run on E85 ethanol and provide consumers a choice at the pump to reduce gasoline consumption are displayed in this handout photo at the US Bio Woodbury Ethanol Plant in Lake Odessa, Michigan 29 May, 2007. GM will offer 14 different US flexfuel models in 2007 like the Chevrolet Impala (front) and the Chevy Silverado (rear), as well as Saab BioPower vehicles like the 9-3 (L) in Europe, and Flexpower models like the Opel Zafira (back R) in Brazil. By 2030, according to the US Department of Energy, 30 percent of the US energy needs could be met by grain based and cellulosic ethanol.
