巴西使用的59％的能量来自生物能源(占28％)和水电(占31％)。使用酒精来代替汽油这一研究项目的成功,使巴西每年可出口40亿升汽油。到1995年这一数字可能上升到每年65亿升。用酒精作燃料也使巴西的制糖业重新恢复了活力。因此,用酒精作燃料的计划为巴西节省了进口石油所需的外汇,保证了能源的安全性,为农村地区提供了就业机会并促进了 59% of the energy used in Brazil comes from bioenergy (28%) and hydropower (31%). The success of the research project using alcohol instead of gasoline has enabled Brazil to export 4 billion liters of gasoline each year. By 1995, this figure could rise to 6.5 billion liters per year. The use of alcohol as a fuel also revived Brazil’s sugar industry. Therefore, the plan to use alcohol as fuel saved Brazil’s foreign exchange required for oil imports, ensured the safety of energy, provided employment opportunities for rural areas and promoted
