直到现在Agrofuel满足能源消费总量的只有一小部分。它满足不到1%的能源消耗。然而生产这样的更少的能量大约有百分之二十三的美国粗粒生产和大约百分之四十的植物油生产的欧洲是利用。一项研究由美国国家科学院说,即使我们所有的玉米和大豆产量则满足使用大约百分之十二的美国汽油需求和大约百分之六的美国对柴油的需求。这是一个非常少量考虑到整个国家的生产将被用于生产生物燃料。这提出了一个严肃的问题是否利用农作物生产生物燃料将是可持续的,相反,它可能是更好的使用以来世界人口的很大部分仍在遭受饥饿(Doornbosch & Steenblik,2008)。
可以努力使用其他可再生能源。除了使用农作物大量的土地和水可以用来生产的作物。这可以产生非常消极的影响人口的粮食安全以及环境。世界看到一个与增长的人口的食物短缺。因此利用农作物生产这些生物燃料是一种决定,需要给定一个沉思(Goldemberg & Guardabassi,2009)。

Till now Agrofuel satisfies only a small portion of the total energy consumption. It satisfied less than 1 percent of the energy consumption. However to produce such less energy approximately twenty three percent of the US coarse grain production and approximately forty percent of vegetable oil production of Europe was utilized. A study done by the US National Academy of Sciences says that even if all the production of corn and soyabeans for US is used then it would satisfy approximately twelve percent of the US demand for gasoline and approximately six percent of the US demand for diesel. This is a very small amount considering the fact that whole of the nation’s production is being used to produce biofuel. This raises a serious question on whether using crops to produce biofuel would be sustainable and instead it could be put to better use since a large section of the world population is still suffering from hunger (Doornbosch & Steenblik, 2008).
Efforts can be made to use other renewable sources of energy. In addition to the usage of crop a vast amount of land and water would be used to produce the crops. This can have a very negative impact on the food security of the population as well as on the environment. World is seeing a shortage of food with the increasing population. Thus using crops to produce these biofuels is a decision which needs to be given a deep thought (Goldemberg & Guardabassi, 2009).
