Cellulosic ethanol can be made from wood, agricultural wastes, and urban trash. It contributes little or nothing to climate change. It can be used to fuel cars, just as gasoline and corn ethanol do today. It can be made from materials common in the upper midwest and throughout the United States. The use of cellulosic ethanol may be one solution to the climate change problem.
