CMU study finds that HEVs and PHEVs with small battery packs offer more emissions and oil displacement benefits per dollar spent than large pack PHEVs and BEVs; policy implications

Green Car Congress

Strategies to promote adoption of hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) with small battery packs offer more social benefits (i.e., We find that, in the base case, plug-in vehicles (PHEVs and BEVs) may produce more damage on average than today’s HEVs.

EIA projects decline in transportation sector energy consumption through 2037 despite increase in VMT, followed by increase

Green Car Congress

For the Transportation sector, EIA projects that energy consumption will decline between 2019 and 2037 (in the Reference case) because increases in fuel economy more than offset growth in vehicle miles traveled (VMT). Light-duty vehicle miles traveled increases by 20% in the Reference case, growing from 2.9 trillion miles in 2018 to 3.5

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

Green Car Congress

If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. The ORNL team analyzed two categories of vehicles: current vehicles as well as future technologies that are not currently in the market but are conceptually valid—for example, CNG hybrid electric concepts.

EIA Energy Outlook 2013 reference case sees drop in fossil fuel consumption as use of petroleum-based liquid fuels falls; projects 20% higher sales of hybrids and PHEVs than AEO2012

Green Car Congress

Increased sales for hybrids and PHEVs. Despite the projected increase in LDV miles traveled, energy consumption for LDVs further decreases after 2025, to 13.0 Reductions in battery electric vehicles are offset by increased sales of hybrid and plug-in hybrid vehicles, which grow to about 1.3 Overall findings.

JEC updates well-to-wheels study on automotive fuels and powertrains; electro-mobility, natural gas and biofuels

Green Car Congress

WTW energy expended and GHG emissions for conventional fuels ICE and hybrid vehicles shows the potential for improvement of conventional fuels and ICE based vehicles. It adds an assessment of electrically chargeable vehicle configurations, such as plug-in hybrid, range extended, battery and fuel-cell electric vehicles. Earlier post.).

Swiss WTW study finds important role for alternative fuels as well as alt drivetrains in move to low-emissions vehicles

Green Car Congress

WTW energy demand and GHG emissions for EV and PHEV drivetrains for various electricity sources; gasoline ICE vehicle is solid square, hybrid the hollow square. Battery-electric range for plug-in hybrids is 60 km, while electric range for full battery-electric and fuel cell vehicles is 180 km. Click to enlarge. Click to enlarge.

MIT, Ford researchers find lightweight conventional vehicles could have lower lifecycle GHG impact than EVs depending upon location

Green Car Congress

In fact, for the midsized cars considered in our analysis, model results suggest that aluminum lightweight vehicles with a combustion engine would have similar emissions to hybrid electric vehicles (HEVs) in about 25% of the counties in the US and lower than battery electric vehicles (BEVs) in 20% of counties.
