Driving a car fueled by something other than gasoline or diesel fuel is no longer the stuff of science fiction. In addition to conventional gasoline and diesel fuel, reformulated — cleaner — gasoline and alternative fuels now are sold in many parts of the country. Alternative fuels such as methanol, ethanol, compressed natural gas, liquefied petroleum gas, and electricity produce fewer tail pipe pollutants than conventional gasoline and diesel fuel. Using them could improve air quality.
