That isn't what the article is about. He is talking about the energy efficiency of capturing solar power via photosynthesis. From the perspective of this article, growing crops for food is just as inefficient.
If acquiring solar energy through biofuels is less efficient than through photoelectric cells or other means then the market will definitely sort this out (though would not directly account for externalities such as carbon pollution).
That makes more sense. But we still pay a premium for energy in a high-density, liquid form that we can pump into vehicles. Of course, that's changing as battery technology improves.
