I don't see myself as an advocate particularly. It's one of the potentially important technologies. It is one of the few technologies that, with coal-fired power, allows you to produce gigawatt-scale, dispatchable electricity—that means it's on when you want it and is not variable—low-carbon electricity.
Both it and nuclear power are quite important, because industrial societies need dispatchable gigawatt-scale power. If you throw both of them out, it gets a lot harder to solve the problem.
But, you know, we can do without any single one of these technologies. What we need is some clear action.
