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. The study investigated the the WTW energy and emissions from the use of natural gas in CNGVs with a range of CNGV fuel economy and natural gas compressor efficiency.

The Next Big Emissions Battle Is Not Cars; It's About Coal

Green Car Reports

The rules for vehicle gas mileage are pretty much locked down from now through 2025. mpg by 2025--or about 42 mpg on their window stickers. It''s coal. The math is complicated, but vehicles in 2025 will have to reach a fleet-wide average of 54.5 So what''s the next battleground over reducing emissions?

UMTRI study shows wide global variability in GHG emissions from operating an EV

Green Car Congress

A team at the University of Michigan Transportation Research Institute (UMTRI) study has assessed the relative amounts of greenhouse-gas emissions from driving a battery-electric vehicle (BEV) compared with greenhouse-gas emissions from driving a traditional gasoline-powered vehicle in different countries of the world. MPG ghg (0.05

FCA says Jeep Wrangler environmental impact reduced by 15% compared to predecessor

Green Car Congress

Improvements are measured by contrasting anticipated CO 2 -equivalent greenhouse-gas (GHG) emissions, with those of comparable vehicles. tons of coal burned in a power-generation plant. These factors include: the environmental impact of fuel production and delivery; material use; and the vehicle’s own fuel consumption.

EIA: light duty vehicle energy consumption to drop 25% by 2040; increased oil production, vehicle efficiency reduce US oil and liquid imports

Green Car Congress

Greenhouse gas (GHG) emission standards and CAFE standards increase new LDV fuel economy through model year 2025 and beyond, with more fuel-efficient new vehicles gradually replacing older vehicles on the road and raising the fuel efficiency of the LDV stock by an average of 2.0% per year, from 21.5 l/100 km) in 2012 to 37.2

EIA: US energy-related CO2 emissions down 2.4% in 2011 while GDP rose

Green Car Congress

It is estimated that the miles per gallon (mpg) of light duty vehicles improved by 1.0% (20.4 mpg) from 2010 to 2011. Since 1949, the 2011 decline in coal generation of more 6% is second only to the decline in 2009 of almost 12%. As recently as 2005, coal’s share of electric power sector generation was more than 51%.
