Abstract: Unfavorable weather can significantly impact the production and provision of agriculture-based biomass feedstocks such as Miscanthus and switchgrass. This work quantified the impact of regional weather on the feedstock production systems using the BioFeed modeling framework. Weather effects were incorporated in BioFeed by including the probability of working day (pwd) parameter in the model, which defined the fraction of days in a specific period such as two weeks that were suitable for field operations.

Transportation fuels are the major component of our energy portfolio. Of the 20 million barrels of petroleum consumed each day in the United States, 68 percent is used in the transportation sector. The Western states are in position to become key producers and beneficiaries in the emerging alternative-fuels economy. We have abundant resources that have great potential as domestic sources for transportation fuels. In 2008, the Western Governors accepted a report and passed a resolution reaffirming their commitment to developing and diversifying the region's transportation fuels portfolio.
This paper examines the impact of biofuel expansion on grain utilization and distribution at the state and cropping district level as most of grain producers and handlers are directly influenced by the local changes. We conducted a survey to understand the utilization and flows of corn, ethanol and its co-products, such as dried distillers grains (DDG) in Iowa. Results suggest that the rapidly expanding ethanol industry has a significant impact on corn utilization in Iowa.
