biofuels
Corn-derived gasoline alternative
Biofuels are fuels derived from organic matter rather than fossil sources.
Ethanol from corn or sugarcane and biodiesel from vegetable oils are the most common types.
Proponents argue biofuels are renewable and carbon-neutral since plants absorb CO2 while growing.
Critics point to land use, food supply impacts, and energy-intensive production: The biofuels mandate drove up corn prices.
