Argument: Carbon sequestration cannot be relied on for oil sands
John Podesta, head of Center for American Progress. June 2010 speech on oil sands: "Unconventional sources of fossil fuels cannot be our energy future. There are no leapfrogging technologies on the horizon that suggest with any plausibility that this could be otherwise. There are no silver bullets waiting to be fired. Notwithstanding the substantial investments our governments are making in RD&D on carbon capture and sequestration, at this point, it is still closer to being on the drawing board than being deployed. For the reasons Dr. Lynch mentioned, investments should not be made on the assumption that CCS is a technology that will make continued production of fossil fuels environmentally and economically viable. Of course, our countries should continue to cooperate on CCS research, as Secretary Chu and Minister Prentice are directing. But for the foreseeable future, “greening” inherently dirty sources of energy does not add up to much more than tinkering at the margins."
