The article's reasoning only works if you assume you're extracting gasoline already refined from the earth. You're not. I'd bet the energetic cost of refining gasoline from crude oil is much larger than that for the coal or "powerplant oil", thus seriously offsetting that 33% vs 50%? This is ignoring the more obvious fact that a powerplant can operate at nearly constant efficiency, while a real car driving on a read road will have a wildly varying efficiency, even with a hybrid engine...) And even if electric is "less green" now, we are kind of sure that we can drive down the price of electric power very low in the future (solar, renewable, classic nuclear, fusion etc. ...only one breakthrough in only one of these will have huge price lowering consequences), while the price of oil can only go up...
