My Decisions Impact Michigan, the U.S. and the World

Did you know that there are cars that do not run on gasoline? Vehicles can run on less polluting fuels such as propane, ethanol, hydrogen and electricity.


Propane is the leading alternative fuel in the country. Today there are more than 200,000 propane vehicles in the United States and about 9 million worldwide. Propane burns cleaner than gasoline, so fewer airborne pollutants are released into the atmosphere. Propane is also less expensive than gasoline, so money can be saved by driving a propane fueled vehicle.

Corn for Ethanol


Ethanol is a clear colorless liquid that is made from starch crops, such as corn. All gasoline powered vehicles can be run on a mixture of gasoline and ethanol which includes up to 10% ethanol. There are special vehicles that can run on mixtures of up to 85% ethanol. Ethanol is a renewable fuel and can help reduce the amount of air pollution released by vehicles. The production of ethanol is also more energy efficient than that of gasoline.
