Study on regional energy balance of biofuel in China

中国是第三大生物燃料生产国，生物燃料被设定为推动中国可再生能源政策的一个非常重要的因素。然而，有人担心，生物燃料的推广将引发诸如与食品竞争等几个问题。本研究评估了从农业残留物（水稻秸秆和小麦秸秆）中提取生物乙醇的潜在生产与省级能源需求之间的差距。结果表明，在农村地区，如安徽省，生物燃料的潜在产量将大于汽油的需求。此外，该研究还审查了政策，例如关于水权交易的政策，以避免在黄河流域推广生物燃料造成的水资源短缺。

China is the third largest biofuel producer, and biofuel is set as a very important factor for the promotion of renewable energy policy in China. However, there are concerns that the promotion of biofuel will cause several problems such as competition with food. This study evaluated the gap between the potential production of bio-ethanol made from agricultural residuals (rice straw and wheat straw) and the energy demand at a provincial level. The results show that the potential production of biofuel will be larger than gasoline demand in the rural area, such as in Anhui Province. Moreover, the study examined the policy, like the one regarding the water right trading to avoid water shortage caused by the promotion of biofuel in the Yellow River Basin.
