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, ...

Fuzzy Logic-based energy efficiency Life Cycle Assessment with a case study of corn-based fuel ethanol in China
A fuzzy logic based method of energy efficiency assessment of Biomass-based Fuel Ethanol (BFE) production is introduced in this paper. Energy relevant inventory variables are defined and described by fuzzy sets representing the differences in energy inventory data between the BFE system and its reference. A fuzzy reasoning process is developed to derive the energy efficiency from the fuzzificated ...

DOE releases first installment of its quadrennial energy review
On April 21, 2015, the U.S. Department of Energy (DOE) released the initial installment of its Quadrennial Energy Review (QER). This first installment focuses on ways to modernize the U.S. energy infrastructure to increase the country's energy competitiveness and security. In its QER, DOE points out that while U.S. biofuel production has increased significantly over the past decade -- due largely ...

Falling Gasoline Use Means United States Can Just Say No to New Pipelines and Food-to-Fuel
Freeing America from its dependence on oil from unstable parts of the world is an admirable goal, but many of the proposed solutions—including the push for more home-grown biofuels and for the construction of the new Keystone XL pipeline to transport Canadian tar sands oil to refineries on the U.S. Gulf Coast—are harmful and simply unnecessary. Gasoline use in the United States is ...

Corn stover for ethanol production: Potential and pitfalls
This study uses a national agro-environmental production model to evaluate the environmental and economic impacts of introducing a market for corn stover to support a stover-based ethanol industry. Prompted by volatility in oil markets, growing concerns about global warming, and an interest in supporting farms and rural communities through stronger agricultural markets, several groups in the ...
