Study finds energy savings of PHEVs relative to HEVs dependent on charging coverage and daily VMT

Green Car Congress

A study based on a spatial and longitudinal travel dataset by a team from Lamar University, Iowa State University and Oak Ridge National Laboratory found that whether plug-in hybrids (PHEVs) have lower energy costs that conventional gasoline vehicles (CGVs) or hybrid-electric vehicles (HEVs) depends on charger coverage.

Study finds removing corn residue for biofuel production can decrease soil organic carbon and increase CO2 emissions; may miss mandated 60% GHG reduction

Green Car Congress

Using corn crop residue to make ethanol and other biofuels reduces soil carbon and under some conditions can generate more greenhouse gases than gasoline, according to a major, multi-year study by a University of Nebraska-Lincoln team of researchers published in the journal Nature Climate Change. —Liska et al. g CO 2 e MJ ?1

Simulations identify potential approach to reducing amount of rare earths required in permanent magnets

Green Car Congress

The rare earths have many unique physical and chemical properties which make them important, if not critical, components in a variety of energy technologies, noted Karl Gschneidner from Iowa State University in a separate presentation at TMS 2011. superconductors in both wind generators and electrical transmission lines.
