In the next 100 years or so, we will run out of fossil fuels. In this film, Nobel laureates Mario Molina and Robert Laughlin challenge three young physicists to think seriously about the energy endgame and their children's futures. Molina believes we can solve the looming crisis through international collaboration -- as happened after he showed that CFCs were damaging the ozone layer. Laughlin disagrees. He wants engineering solutions, and says nations will go to war unless we find them.
