@maxdancona,
I suspect the authors of the data you cited were a bit biased in their modelling For example, they attribute a share of the costs (or emissions) if extracting, refining and distributing gasoline for conventional vehicles, but it is not evident that they do the same for the extraction & processing for the, coal or natural gas used in generating the electrical power, or the lithium and other materials used in electrical vehicles; or the mechanical efficiency of the transmission and drive train in an electrical vehicle. All these elements are included in the reference data for conventional vehicles.
For reference the Thermal efficiency of a modern coal fired plant is ~ 34% while that for a combined cycle gas fired plant is ~56%. Transmission efficiency through the electrical grid and local low voltage lines is ~ 94%, and that for charging & discharging a battery is ~98%. Throw in the 80% efficiency of the transmission & drive train of an electrical vehicle and you get 24% thermal efficiency for battery powered autos using coal generated electrical power and 41% for gas generation plants. These figures do not include the coasts for extracting, processing and delivering the gas and coal used , as is included in the comparisons with conventional autos. If this was done the above efficiencies would be reduced significantly.
The equivalent thermal efficiency of modern automobiles ranges from 25% to 50%. The data in your source appears to attribute fuel production emissions to conventional autos but not to electrical vehicles and their ultimate power sources.
Unlike all electrical vehicles Hybrid engines are indeed much more efficient, using a constant speed, highly efficient engine to charge the battery and propel the vehicle at constant speeds; and the battery & motor for acceleration & transients. It's a good combination of the best features of both sources.
Thanks for your comments regarding Setanta's post. I'm indifferent to his irritable assaults. He's an interesting guy but is unfortunately locked inside a miserable personality. He punishes himself far more than those he attacks.
