Ethanol
So now ethanol prices are collapsing, because there's no way to get the ethanol distributed to lots of cars quickly and as a result demand isn't materializing.
The economy isn't going to go green (let's not debate just now how green is corn) unless supply, distribution, and demand are all addressed.
Ethanol has a distribution problem. But solar, for instance, has a pricing problem. What is the long run outlook for solar pricing?
We can't swear off oil unless pricing is reasonably dependable for alternative energy sources. No one is going to invest really big money in alternatives unless they can predict prices with some certainty.
None of these problems is too hard to solve, but merely saying we need a carbon tax doesn't produce distribution for ethanol. Merely saying we want to tax carbon doesn't suppress the market demand for oil even at a 25% increase in price (what is now being predicted and prepared for.
