Robert Laughlin of Stanford University and the 1998 co-recipient of the Nobel Prize in Physics talks with EconTalk host Russ Roberts about energy use and the future of the earth's climate. Drawing on his forthcoming book on energy, Laughlin predicts that we will continue to use cars and planes and electricity long after coal and petroleum are exhausted and speculates as to how that might play out in the future. The conversation concludes with discussions of other concerns of Laughlin's--the outlawing via legislation and taboo of certain forms of knowledge, and the practice of reductionism rather than emergence in the physical sciences.
