This research examines whether sweet sorghum, a crop considered more drought-tolerant and suitable for semi-arid areas than corn, could result in an economically viable sweet sorghum ethanol pathway in the Great Plains. We find that that if the D5–D6 RIN price spread exceeds the $0.35/gal recently experienced, the benefits of the pathway would be equivalent to about $90/acre of sweet sorghum, or $0.38/gal of ethanol. Because of sparse cultivation potential, only four the six existing plants in the Nebraska–Colorado High Plains area might expect transportation costs to be low enough for economic feasibility.

Ethanol And Food Prices - Preliminary Assessment, Richard K. Perrin

Food prices in the U.S. rose dramatically in 2007 and early 2008. Given the integration of the world markets for foodstuffs, prices increased around the world as well, leading to riots in a number of countries in early 2008. The popular press has tended to attribute these food price increases to demand for corn by the ethanol industry. Grain prices are one determinant of food prices, but they constitute less than 5% of food costs in the U.S.(a higher percentage elsewhere.) This paper focuses on the likely relationship between ethanol and food prices, ignoring the potential role of other important …

Grain Ethanol - Why Consider Food For Fuel?, Richard K. Perrin

Current U.S. energy policy encourages additional ethanol production through a combination of subsidies and mandates. Grain ethanol production converts a potential food into fuel. Concerns have been expressed that this drives up the price of food, and could contributed to world hunger problems. Other objections to grain ethanol have been raised: it might not reduce greenhouse gases much if at all; intensified cropping could deteriorate environmental resources, and it might increase smog in cities. Why, then, do proponents favor increased grain ethanol production? It is possible that it will educe greenhouse gas emissions; it can reduce petroleum imports, it can …
