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. 2013.12.054.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

EPA Trends on EVs and PHEVs; beginning of a “measurable and meaningful impact” on new vehicle fuel economy and emissions

Green Car Congress

Thus, for the first time, in the newly released 2014 edition of the Trends report, EPA presents a brief analysis of the impact of alternative fuel vehicles on overall new vehicle fuel economy and CCO 2 O2 emissions. In this tally, the BMW i3 counts as an EV in its battery-only configuration and as a PHEV when equipped with a range extender.)

EPA proposes stringent new emissions standards for light-, medium-, heavy-duty vehicles for MY 2027 and beyond

Green Car Congress

The proposed standards are projected to result in an industry-wide average target for the light-duty fleet of 82 grams/mile (g/mile) of CO 2 in MY 2032, representing a 56% reduction in projected fleet average GHG emissions target levels from the existing MY 2026 standards.

Obama orders GHG cuts for Federal Agencies; 50% of all new agency vehicles to be ZEV or PHEV by 2025

Green Car Congress

President Obama today signed a wide-ranging executive order mandating cuts in greenhouse gas emissions for Federal agencies. Through more efficient Federal operations, agency direct greenhouse gas emissions can be cut by at least 40% over the next decade, the order suggests.
