      abstract = {Agricultural and energy commodity prices have  traditionally exhibited relatively low – even negative  correlation. However, the recent increases in biofuel  production have altered the agriculture-energy relationship  in a fundamental way. The amount of corn utilized for  ethanol production in the US has increased from 5% in 2001  to over one-third by the end of the decade. This increase  has drawn corn previously sold to other uses (exports,  food, feed), as well as acreage devoted to other crops  (e.g., oilseeds and other grains). In addition, there has  been an increase in the demand for production inputs,  especially fertilizers, which are heavily energy-intensive.  In short, the previous "biofuel decade" has led to  significant changes in the US, and indeed the global  economy. },
