I would say the key thing again is to focus on accelerating the development of technology that will replace emitting generation. It looks to me like investment in clean coal technology, R and D, and beyond that in terms of actually supporting projects that are prepared to take the first step to move along that path. It's clean coal technology in all its forms. It could be gasification or it could be oxygen combustion.
There's a whole range of new technologies, plus retrofit opportunities, recognizing that 90% of the emissions we'll have in ten years will come from the existing stock we have today. The ability to actually make changes to existing stock will also be important. It needs a lot of work in technology.
