There is significant momentum behind natural gas extraction efforts in the United States, with many states embracing it as an opportunity to create jobs and foster economic strength. Natural gas extraction has also been championed as a way to move toward energy independence and a cleaner energy supply. First demonstrated in the 1940’s, hydraulic fracturing is now the predominant method used to extract natural gas in the U.S.
Shale gas is changing the American energy economy at a breakneck pace, and its rapid, widespread domestic utilization is redefining the questions our government must address about energy security, policy and the environment. Shale gas as an energy source poses a huge potential boon to American manufacturers of all stripes, but the relationship between the shale gas boom and U.S manufacturing competitiveness needs clearer understanding.
ABSTRACT. Public policy supports biofuels for their benefits to agricultural economies, energy security and the environment. The environmental rationale is premised on greenhouse gas (GHG, "carbon") emissions reduction, which is a matter of contention. This issue is challenging to resolve because of critical but difficult-to-verify assumptions in lifecycle analysis (LCA), limits of available data and disputes about system boundaries. Although LCA has been the presumptive basis of climate policy for fuels, careful consideration indicates that it is inappropriate for defining regulations.
The climate benefits of biofuels such as ethanol and biodiesel have been debated for many years. Attempts to compare these fuels with one another and fossil-derived fuels such as gasoline and diesel confront many uncertainties, not all of which can be resolved through further data analysis. By scrutinizing the greatest sources of uncertainty and grounding analysis in the areas of high certainty such as combustion chemistry and the terrestrial carbon cycle, this paper sheds light on this challenging subject and points the way toward new strategies for addressing CO2 emissions from transportation fuels.
Since 2005, the United States has embarked on a steady expansion of renewable fuels such as ethanol and biodiesel, widely touted as a win-win proposition for energy security and the environment. However, the promised breakthroughs in biofuel technology have greatly lagged the rapid ramp-up of production mandated by Congress while adverse side effects of the policy have become ever more clear.

TRB Special Report 311: Effects of Diluted Bitumen on Crude Oil Transmission Pipelines analyzes whether shipments of diluted bitumen have a greater likelihood of release from pipelines than shipments of other crude oils. The oil sands region of Canada is the source of diluted bitumen shipped by pipeline to the United States.
Dedicated in Fall 2013 and currently nearing completion, the Battery Fabrication and Characterization User Facility is a space developed in cooperation with the Michigan Economic Development Corporation and Ford Motor Company. This lab will enable industry and university researchers to collaborate on developing cheaper and longer lasting energy-storage devices in the heart of the U.S. auto industry. The new facility — for prototyping, testing and analyzing batteries and the materials that go into them — promises to be a key enabler for Southeast Michigan's battery supply chain.
