Alternative-fuel cars are no carbon cure-all

June 12, 2013 8:31 am | News | Comments

Making cars more fuel-efficient is great for reducing greenhouse gas emissions, but rather than promoting sales of electric and other alternative-fuel vehicles, policymakers should turn their focus to cutting emissions in other energy sectors—from oil wells and power plants to farms and forests affected by biofuels production—says a Univ. of Michigan researcher.

Oil drilling technology leaps, clean energy lags

May 2, 2013 1:52 pm | by JONATHAN FAHEY - AP Energy Writer - Associated Press | News | Comments

Technology created an energy revolution over the past decade—just not the one we expected. By now, cars were supposed to be running on fuel made from plant waste or algae—or powered by hydrogen or cheap batteries that burned nothing at all. Electricity would be generated with solar panels and wind turbines. When the sun didn't shine or the wind didn't blow, power would flow out of batteries the size of tractor-trailers.

Study reveals potential for deep cuts to petroleum use, emissions

March 19, 2013 4:16 pm | News | Comments

The U.S. Department of Energy's National Renewable Energy Laboratory and Argonne National Laboratory this week announced the release of the Transportation Energy Futures study, an assessment of avenues to reach deep cuts in petroleum use and greenhouse gas emissions in the transportation sector. The project suggests opportunities for 80% reductions by 2050

Obama wants research to wean vehicles off oil

March 15, 2013 6:01 am | by MATTHEW DALY - Associated Press - Associated Press | News | Comments

President Barack Obama is pushing Congress to authorize more federally funded research into clean energy technologies that can wean automobiles off oil. Obama proposed the idea of an energy security trust last month in his State of the Union address, but he was putting a price tag on the idea during a trip Friday to the Argonne National Laboratory outside Chicago—$2 billion over 10 years.

Agreement will lead to grid-friendly electric vehicle charging

March 7, 2013 3:16 pm | News | Comments

A technology that will allow widespread adoption of plug-in electric vehicles without negatively impacting the electrical grid is the subject of a commercial license agreement between Battelle and AeroVironment, Inc., of Monrovia, Calif. The technology may also ultimately result in lower costs for plug-in electric vehicle owners.

Ford, Daimler, Nissan to research hydrogen cars

January 28, 2013 10:39 am | by TOM KRISHER - AP Auto Writer - Associated Press | News | Comments

Ford is joining with Daimler and Renault-Nissan to speed development of cars that run on hydrogen, with hopes of bringing a vehicle to market in as little as four years. Hydrogen fuel cell vehicles generate electricity after a chemical reaction between hydrogen and oxygen. Hydrogen is stored in special high-pressure tanks, and the only emissions are water vapor and heat.

The “rebound” effect of energy-efficient cars overplayed

January 24, 2013 8:18 am | News | Comments

The argument that those who have fuel-efficient cars drive them more and hence use more energy is overplayed and inaccurate, a University of California, Davis economist and his co-authors say in a comment article published in Nature.

Photovoltaics beat biofuels at converting sun's energy to miles driven

January 17, 2013 10:51 am | News | Comments

University of California, Santa Barbara researchers debate which makes more sense, growing fuel crops to supply alternative-fuel vehicles with ethanol and other biofuels or using photovoltaics to directly power battery electric vehicles?

NREL launches interactive tool for developing a cleaner energy future

January 15, 2013 2:20 pm | News | Comments

The U.S. Department of Energy's National Renewable Energy Laboratory has created an energy analysis tool to help individuals and educators experiment with future energy use scenarios. The interactive Buildings, Industry, Transportation, Electricity, and Transportation Scenarios (BITES) allows users to explore how changes in energy demand and supply can impact carbon dioxide emissions and the current U.S. energy trajectory.

Researchers seek longer battery life for electric locomotive

January 4, 2013 9:34 am | News | Comments

Norfolk Southern Railway No. 999 is the first all-electric, battery-powered locomotive in the United States. But when one of the thousand lead-acid batteries that power it dies, the locomotive shuts down. To combat this problem, a team of Penn State University researchers is developing more cost-effective ways to prolong battery life.

New factor could limit life of hybrid and electric car batteries

December 13, 2012 8:02 am | News | Comments

A new study of the batteries commonly used in hybrid and electric-only cars has revealed an unexpected factor that could limit the performance of batteries currently on the road. Researchers led by Ohio State University engineers examined used car batteries and discovered that over time lithium accumulates beyond the battery electrodes—in the "current collector," a sheet of copper which facilitates electron transfer between the electrodes and the car's electrical system.

A closer examination of electric vehicles and the power grid

December 12, 2012 3:32 pm | News | Comments

As plug-in electric vehicles become an ever-more central part of America's daily life, University of Notre Dame researchers are anticipating what that development will mean for the nation's power grid. Under funding from the National Science Foundation's Cyber-Physical Systems Program, a research group is attempting to develop mathematical algorithms to help guide the integration of plug-in hybrid electric vehicles into the power grid.
