Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

Relative changes in vehicle energy efficiency (VEE) (km/MJ) on ethanol/gasoline blends over those on gasoline for different blending levels. Several recent highly cited LCAs that have incorporated vehicle efficiency differences between gasoline and ethanol/gasoline blends could potentially be misleading. Click to enlarge.

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

Green Car Congress

Factors influencing the decrease included: In 2011, transportation-related carbon dioxide emissions fell primarily due to higher fuel costs, improvements in fuel efficiency, and a reduction in miles traveled. In 2010, the price of regular gasoline averaged $2.78 mpg) from 2010 to 2011. per gallon.

Ford researchers: global light-duty CO2 regulatory targets broadly consistent with 450 ppm stabilization

Green Car Congress

Further, the study compares 450 ppm LDV CO 2 glide paths derived using only vehicle efficiency improvements against those derived using both vehicle and fuel actions. The SMP model calculates 2000?2050 They converted from an absolute amount to scale relative to 2000. Because of the high LDV emissions in 2000?2010,

Tech: How do Hybrid & Plug-in Hybrid Batteries Recharge? Do I Need to Plug a Hybrid In?

Clean Fleet Report

When the first gasoline-electric hybrids vehicles began arriving in 1999 and 2000, early adopters did their research and were quite knowledgeable about the then-new and revolutionary transportation mode. But the mass market was confused; these new cars had an additional battery to provide electricity to an electric motor.

US EIA Reports Record-setting 7% Overall Decline in US Carbon Dioxide Emissions in 2009; Transport Emissions Down 4.1%, Lowest Percentage Reduction of the End-UseSectors

Green Car Congress

Carbon intensity changes in the electric power and industrial end use sectors. In 2009, the carbon intensity of the electric power sector decreased by nearly 4.3%, primarily due to fuel switching as the price of coal rose 6.8% The average decline in energy intensity from 2000 to 2008 was 2.0%. mpg US in 2009.

Toyota Introduces Hybrid Version of the Auris 2010, Optimal Drive for Gasoline and Diesel Units

Green Car Congress

In addition to the hybrid model, the Auris 2010 powertrain line-up also offers three gasoline and three diesel engines offering the performance and economy-enhancing benefits of Toyota Optimal Drive. Combined cycle fuel consumption is calculated to be 3.8 L/100km (62 mpg US), with CO 2 emissions of 89 g/km. Earlier post.).
