But to give just one example--the single most energy intensive step in ethanol production is the distillation step, which happens around 100 deg. C. Just ONE step in the production of gasoline (catalytic cracking) happens at hundreds of degrees C. And that is just one of dozens of refining steps necessary to produce gasoline.
