As the world’s largest automobile markets, the United States and China lead the world in oil consumption, importing more than half the petroleum they consume. The CERC-Clean Vehicles Consortium seeks to reduce this oil consumption by supporting the joint research of the nations’ leading experts in clean vehicle technologies. The University of Michigan’s Prof. Huei Peng and Tsinghua University’s Prof. Minggao Ouyang lead this effort.
This National Research Council (NRC) report assesses the potential to achieve twin goals of reducing petroleum use and cutting greenhouse gas (GHG) emissions from U.S. cars and light trucks to 80 percent below the 2005 level by 2050.
ABSTRACT. Improving the fuel efficiency of automobiles (cars and light trucks) is an important means of addressing transportation oil demand and greenhouse gas (GHG) emissions. This report examines the efficiency attainable through evolutionary changes in U.S. automobiles that have fueling characteristics as well as performance, size and other attributes similar to those of today. The analysis combines results from previous engineering studies of powertrain efficiency and load reduction with new examinations of rates of technology change and cost reduction.
With the backing of 13 car companies, the United Auto Workers and other parties, the Obama Administration announced the biggest step forward on auto efficiency in over a generation. The new Corporate Average Fuel Economy (CAFE) regulations just finalized target the greenhouse gas emissions equivalent of 54.5 mpg by model year 2025, double the efficiency of this year's vehicle fleet.
Building on the Bush Administration's 2007 proposal to raise automotive fuel economy by up to four percent per year, the Obama Administration is now considering regulations that might target a doubling of Corporate Average Fuel Economy (CAFE) standards by 2025. But just how much can the efficiency of cars and light trucks be improved, and at what cost?
A new report from a University of Michigan researcher estimates that, even without going electric, U.S. cars and trucks could achieve an average efficiency of 74 miles per gallon by 2035. Compared to a federal 2005 Corporate Average Fuel Economy (CAFE) baseline, that’s a tripling of fuel economy.
Autonomous "robot" vehicles that can drive themselves hold great promise for transforming transportation systems across the world. Part of their appeal is the potential to greatly improve energy efficiency and reduce emissions. Not so fast, notes Bradley Berman in a critical piece on ReadWriteDrive, where he quotes Energy Institute research professor John DeCicco's admonition that technology "doesn't save us from ourselves."
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.
More and more plug-in electric vehicles are hitting the roads each year, but is the technology really close to a tipping point for mass-market growth? In this analysis piece for the Society of Automotive Engineers (SAE), U-M Energy Institute research professor John DeCicco argues that the real turning point for EVs will come only after transportation systems are automated for driverless operation.
