We examine four scenarios for the evolution of the biofuel sector using a partial equilibrium model of the world agricultural sector. The model includes the new Renewable Fuels Standard in the 2007 energy act, the two-way relationship between fossil energy and biofuel markets, and a new trend toward corn oil extraction in ethanol plants. At one extreme, one scenario eliminates all support to the biofuel sector when the energy price is low, while the other extreme assumes no distribution bottleneck in ethanol demand growth when the energy price is high. Of the remaining two scenarios, one considers a pure market ...


Structural Shifts In Agricultural Markets Caused By Government Mandates: Ethanol And The Renewable Fuels Standard, John C. Olson May 2009

Structural Shifts In Agricultural Markets Caused By Government Mandates: Ethanol And The Renewable Fuels Standard, John C. Olson

All Graduate Theses and Dissertations

For many decades, demand for agricultural commodities has remained stagnant and its growth has been limited. In contrast, agricultural production continues to become ever more efficient by increasing output for stable or decreased inputs. Long-run profits have historically been near zero due to an ongoing relative equilibrium. But recent U.S. energy policy has changed to include a Renewable Fuels Standard (RFS), the goal of which is to boost domestic energy independence in an environmentally sound way. Most of the RFS in the near-term relies on the production of 15 billion gallons of ethanol made from corn. This has the ...

Land Allocation Effects Of The Global Ethanol Surge: Predictions From The International Fapri Model, Jacinto F. Fabiosa, John C. Beghin, Fengxia Dong, Amani E. Elobeid, Simla Tokgoz, Tun-Hsiang (Edward) Yu Mar 2009

Land Allocation Effects Of The Global Ethanol Surge: Predictions From The International Fapri Model, Jacinto F. Fabiosa, John C. Beghin, Fengxia Dong, Amani E. Elobeid, Simla Tokgoz, Tun-Hsiang (Edward) Yu

CARD Working Papers

We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market, multi-commodity international FAPRI (Food and Agricultural Policy Research Institute) model. The model incorporates the trade-offs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade. We examine land allocation by type of crop, and pasture use for countries growing feedstock for ethanol (corn, sorghum, wheat, sugarcane, and other grains) and major crops competing with feedstock for land resources such as oilseeds. We shock the model with ...


Temperature Influence And Heat Management Requirements Of Microalgae Cultivation In Photobioreactors, Thomas Hagen Mehlitz Feb 2009

Temperature Influence And Heat Management Requirements Of Microalgae Cultivation In Photobioreactors, Thomas Hagen Mehlitz

Master's Theses and Project Reports

Microalgae are considered one of the most promising feedstocks for biofuel production for the future. The most efficient way to produce vast amounts of algal biomass is the use of closed tubular photobioreactors (PBR). The heat requirement for a given system is a major concern since the best algae growth rates are obtained between 25-30 °C, depending on the specific strain. A procedure to determine temperature influence on algal growth rates was developed for a lab-scale PBR system using the species Chlorella. A maximum growth rate of 1.44 doublings per day at 29 °C (optimal temperature) was determined. In ...


Three Essays Concerning Agriculture And Energy, Mindy Lyn Baker Jan 2009

Three Essays Concerning Agriculture And Energy, Mindy Lyn Baker

Graduate Theses and Dissertations

This dissertation consists of three papers, each regarding a particular aspect of the relationship between energy and agriculture. The objective of the first paper is to create a model that will enhance informed policy decisions regarding the bioeconomy. A forward-looking stochastic model captures the effect of uncertainty in crude oil prices and commodity yields on biofuel industry development. Acreage limitations on feedstocks such as corn, soybeans, and switchgrass are shown to create competition for acreage among the crops. Investors in the model are rational in the sense that they engage in biofuel production only if returns exceed what they expect ...


Ethanol In The Media Agenda: The Life Cycle Of An Issue In Different Geographic Areas, Shoshana Esther Hebshi Jan 2009

Ethanol In The Media Agenda: The Life Cycle Of An Issue In Different Geographic Areas, Shoshana Esther Hebshi

Graduate Theses and Dissertations

The rise of ethanol as a fuel alternative has come with much controversy over its true benefits. Much of this debate has been played out in the media. This study aims to determine patterns in media coverage of ethanol through a content analysis of reports published from 1999 to 2008 in three newspapers whose respective service areas exhibit different dispositions about the topic--the Des Moines Register, the Houston Chronicle and the Fresno Bee. The study also aimed to expand on the attributes of coverage within each identified phase of the coverage cycle

The study found only one cycle of pre-hoopla ...
