As we enter the 21st century, policy-makers face complex decisions regarding options for meeting the demand for transportation fuels. There is now a broad scientific consensus that the burning of fossil fuels has been contributing to climate change,1 and the transportation sector is a major contributor (see Figure 1). Yet global demand for energy and transport fuel is rapidly rising.
Understanding the environmental effects of alternative fuel production is critical to characterizing the sustainability of energy resources to inform policy and regulatory decisions. The magnitudes of these environmental effects vary according to the intensity and scale of fuel production along each step of the supply chain. We compare the spatial extent and temporal duration of ethanol and gasoline production processes and environmental effects based on a literature review and then synthesize the scale differences on space-time diagrams.

Optimal Biorefinery Locations and Transportation Network for the Future Biofuels Industry in Illinois
This article addresses development of the Illinois ethanol industry through the period 2007-2022, responding to the ethanol production mandates of the Renewable Fuel Standard by the U.S. Environmental Protection Agency. The planning for corn-based and cellulosic ethanol production requires integrated decisions on transportation, plant location, and capacity.
This dataset provides a listing of U.S. locations where ethanol transloading occurs as of April 2010. Transloading happens when railcars carrying ethanol are spotted at a specifici rail station, facility or siding that allows tanker trucks to pull alongside and transfer ethanol to the truck. The trucks then make deliveries of ethanol to blending terminals associated with the gasoline/petroleum pipeline delivery systems to be mixed into E10 or E85 prior to delivery to commercial refueling stations.
This dataset provides a listing of U.S. locations where unit train deliveries of ethanol occur as of April 2010. A unit train, also called a block train, is a rail train in which all the cars making it up (the consist) are shipped from the same origin to the same destination, often carrying only one commodity, without being split up or stored en route. The train requires only assembly at the point of origin, with assembling and disassembling trains at rail yards being unnecessary.
In January 1976, the Transportation Energy Conservation (TEC) Division of the Energy Research and Development Administration contracted with Oak Ridge National Laboratory (ORNL) to prepare a Transportation Energy Conservation Data Book to be used by TEC staff in their evaluation of current and proposed conservation strategies. The major purposes of the Data Book were to draw together, under one cover, transportation data from diverse sources, to resolve data conflicts and inconsistencies, and to produce a comprehensive document.

This article investigates ethanol and its integration into the petroleum supply chain. Recent state and federal mandates require varying levels of ethanol in reformulated gasoline (RFG) and, consequently, new complexities are being introduced into what has to this point been a streamlined petroleum supply chain.
