In the article it explains that ethanol has less BTUs than gasoline. Therefore, a $3 gallon of gasoline has the same energy as a $4+ gallon of ethanol.

Not only that, putting ethanol into gasoline actually increases the cost of the gasoline since ethanol is more expensive. It's expense comes from the fact that it is very expensive to produce, and the resulting product from original source is far less than gasoline from crude. No, ethanol is not the answer. Hydrogen is probably a far better, albeit more expensive, solution. And, yes, I am aware that as the new fuels become more prevalent the costs of production will decrease.

I think what you meant to say was that a $3 gallon of gasoline has the same energy as a $4+ gallon-and-a-half of ethanol. (gasoline has about 50% more Btu/volume)
