Re:Thanks for the attempt
Yep, mixed up the L/km bit (clearly we need more fuel efficient cars in North America...). The point was, in using either figure, he's accounted for the engines efficiency, which you seem to think he didn't. Since I remain confused by what exactly he's done "fundementally wrong" in his calculation, can you do it for me. What is the energy consumption per day of a Petrol car, running on gas, going 50 km a day with a fuel economy of 12km/L. He says 40kWh, you say he's wrong. Fair enough, what is it? Remember, the point of that section was to calculate this value, not that of an electric car. I don't care what an electric car gets, it's not what he was calculating.
As an aside, if he "has the nerve of presenting his arguments as the final word in the renewables debate", what exactly are you, I or anyone else doing? We're all presenting arguments....the nerve! His is one of the most balanced I've seen. By admitting you've an axe to grind, you're admitting to a lack of objectivity. That's great for an amusing argument, but not so great for intelligent policy.
