CrossTalk on post-oil

­On this edition of Peter Lavelle's CrossTalk, he asks his guests how long the world can remain addicted to oil. What is, or should be, our energy future? Should we embrace green technology to replace our current addiction to carbon fuels? (Though there are those who believe this an unrealistic scam at the moment). Is the future path nuclear
energy, considered by many as far safer today than a generation ago? A combination of both? Or is oil the only real answer for the near and medium term?
