“Ethanol — the gasoline substitute made by distilling corn or other vegetation — has long been the subject of intense debate. According to its critics, ethanol does little to improve air quality and may actually contribute to smog, it costs taxpayers billions of dollars in subsidies, and it doesn’t do much to reduce our dependence on foreign oil. Ethanol’s defenders say its environmental effects are more positive than negative, the so-called subsidies are mostly federal and state tax breaks, and as the cost of making ethanol falls while the cost of fossil fuels remains high, ethanol could substantially reduce the nation’s oil consumption and even overtake gasoline as the preferred transportation fuel.” (03/06)
