Comments on: Electric Vehicles – CO2 from Electricty vs Gasoline

The tables show total electricity produced, divided by the total CO2 emissions and therefore don’t consider transmission losses. For the gasoline numbers, it is pure conversion of gasoline (via burning) into it’s parts, including CO2… this number does not include the background CO2 production to drill the wells, transport the crude, refining and distribution.

A potentially significant omission is how you are evaluating co2 production in electricity generation. Distribution of electricity via grid generally results in 50% loss. Does your estimate deal with co2 production for distributed electricity or original generation.

Correct… thanks for catching that typo….fixed now.

You appear to have a typo here–”Even if your fuel efficient Hybrid gets 60 miles to the gallon, you are still producing 10 pounds of CO2 versus 8 pounds for the plug-in vehicle.” Surely you mean to say that the 60 mpg Hybrid produces 18, not 10 pounds of CO2, given the 18 pounds of CO2 per gallon of gas.
