Without belaboring the events of the last five years, virtually every one of those trends has reversed course. That has occurred partly as a result of the recession and the lasting changes it produced in the US economy, and partly due to an energy revolution that was largely invisible in 2007 but had already begun.
US gasoline consumption peaked in 2007 and has since declined to 133 billion gal/yr last year. The EIA forecasts it to fall to 128 billion by 2020 and 113 billion by 2030. US crude oil output is the highest in 22 years and is set to exceed imports this year, while the US has become a net exporter of gasoline and other petroleum products. Since 2007 US ethanol production has grown from 6.5 billion gal/yr to 13.3 billion gal., and it seems more than coincidental that corn prices had doubled to an average of $6.22/bu by last year.
