出于能源安全、促进农村经济发展、保护环境等方面考虑,美国政府大力倡导和扶持生物燃料生产,导致美国成为世界上最大的生物燃料生产和消费国。生物燃料生产对美国经济发挥了极大的推动作用,同时也对国际粮油市场产生了巨大影响。 For reasons of energy security, promotion of rural economic development and protection of the environment, the U.S. government strongly advocates and supports biofuels production, leading the United States to become the largest biofuel producer and consumer in the world. Biofuel production has played a significant role in boosting the U.S. economy and has also had a huge impact on the international grain and oil markets.
