Mr. Watson, you cannot decarbonize your economy overnight. You can start to inform the people who make the investment of the best way to make that investment. The only way, at least that I know, is to have a price mechanism. If you don't have a price mechanism, you make a cost-plan type of decision, because we are driven by a market economy, and that is driven by price. It may not be the ideal situation, but that's what we have right now.
