Upland switchgrass yield, nutritive value, and soil carbon changes under grazing and clipping
There have been few evaluations of switchgrass (Panicum virgatum L.) cultivars under multiple harvest managements in the northeastern United States. The objective of this study was to determine the yield, nutritive value, and soil C changes of switchgrass cultivars under grazing and clipping. In 1999, ‘Cave-in-Rock’, ‘Trailblazer’, and ‘Shawnee’ switchgrass were established in field plots at Rock ...

Yield and breakeven price of ‘Alamo’ switchgrass for biofuels in tennessee
Research on how land suitability affects yields and breakeven prices for switchgrass (Panicum virgatum L.) grown as a bioenergy crop is lacking for the U.S. Southeast. Data from a 3-yr multilocation experiment at Milan, TN, were analyzed to determine the influence of soil drainage and landscape position on switchgrass yield and farm-gate breakeven price. Plots were seeded in 2004 with ‘Alamo’ at ...

Current and future ethanol production technologies: costs of production and Rates of Return on invested capital
Considering the production goals for cellulosic and advanced biofuels in the Energy Independence and Security Act of 2007 (EISA), this study compares production costs and returns on invested capital for two current and three proposed ethanol technologies. Two methods use corn grain as the feedstock, and three use cellulosic feedstocks of corn stover, switchgrass and wood chips. Baseline levels ...

EPA Anticipates That Sorghum Based Biofuels Could Qualify For RFS
EPA announced that renewable fuels produced from sorghum biomass could qualify as cellulosic fuel under the Renewable Fuel Standard (RFS). This is a result of a preliminary analysis of the Greenhouse Gas (GHG) emissions resulting from the growth and transport of biomass sorghum feedstocks that are used to make biofuels. The analysis, which was conducted in response to a petition from the National ...

Bioenergy and land use: a spatial-agent dynamic model of energy crop production in Illinois
To reduce dependence on foreign oil and natural gas and address concerns about climate change, the USA is increasingly developing renewable, domestic energy sources, notably biomass for the production of ethanol and biodiesel. Illinois, as one of the farming states of the Midwest, has significant potential to produce bioenergy crops. Land requirements place these crops in competition with ...

How RFS Biofuel Mandates Drive Imports
It should come as a surprise to congressional supporters of the Energy Independence and Security Act (EISA), that their 2007 votes to expand the Renewable Fuel Standard (RFS) to advance “homegrown energy” would lead to historic U.S. imports of biodiesel. Here’s a look at how exactly that’s happening: Though the conventional requirement can be met with various biofuels, ...

Peak Oil – Peak Opportunity?
Possibility and public policies can harness renewable energy technologies for a bright future “Alternative” fuels are nothing new. In fact, they were the mainstream power source a century ago. Rudolph Diesel built his engine to run on peanut oil. Henry Ford designed the Model T to run on ethanol. Wind delivered a significant source of power in the last century. Cheap gasoline (and ...
