The best way to characterize this until now I think is that there's been too much emphasis on the supply side of the equation. It certainly plays its role in reducing carbon emissions, but there are also many demand-side solutions, as we call them, like energy efficiency and others, that can provide equal if not greater benefits and create more jobs than some of the other solutions. These just haven't received the attention they deserve. They represent a tremendous opportunity to reduce carbon and a host of other environmental impacts.
