据美国国会技术评估室研究预测,美国到八十年代末,若使用酒精汽油,每年可节省三千五百万到八千万加仑的汽油及其他有关能源。如果计划从巴西出口一亿二千万加仑乙醇的话,则每年可取代九千五百万加仑的汽油。酒精汽油以玉米为原料,随之会增加耕种面积、肥料及杀虫剂。由于能源与粮食争用土地,将导致粮食价格的急剧上涨。因此,美国国会对酒精汽油的生产尚未确定。这主要取决于未来农产品的价格和原料的获得及成本等因素。
According to a study by the U.S. Congressional Technology Assessment Office, the United States can save between 35 and 80 million gallons of gasoline and other related energy sources by the end of the 1980s if it uses alcoholic gasoline. If you plan to export 120 million gallons of ethanol from Brazil, you can replace 95 million gallons of gasoline each year. Alcohol gasoline uses corn as a raw material, which in turn will increase the area under cultivation, fertilizers and pesticides. As energy and food compete for land, it will result in a sharp rise in food prices. Therefore, the United States Congress on the production of alcoholic gasoline has not been determined. This depends mainly on the future price of agricultural products and the availability of raw materials and costs and other factors.
