$2.50 a Gallon?

The demand for gasoline is ever-growing but supply capacity is peaked. In the article, Analysts: Crude Could Hit $60 a Barrel, it states that we should be expecting $2.50 a gallon somewhere in spring. After spring, I believe gas prices will get even higher. I do not see the demand for gas diminishing any time soon. This made me think of substitute goods, as the price for gas increases, the benefit of a substitute increases. I believe the trend for hydrogen and alcohol fueled cars will rise. There are a few motor companies that are investing in these substitute goods; I feel these companies will be a good investment in the long run.
