Fuelling controversy: We are facing a global energy crisis, and scientists are charged with finding alternatives to fossil fuels. In this film, Nobel laureates Steven Chu and Hartmut Michel visit a farm with three young researchers to consider our energy future. They ask whether biofuels can power the planet and, if not, what are the alternatives? The researchers are full of optimism but Chu former US Secretary of Energy brings them back down to earth with the harsh reality of economics, while Michel envisions a future powered by clean electricity.
