Nova Sciencenow

Steven Chu is the U.S. Secretary of Energy under President Obama. He’s a Nobel Prize-winning physicist, and a big proponent of renewable power, like wind and solar. He says that although they’re essential to fight climate change, that’s only one reason we should adopt them in the United States. Another reason is purely economic—there’s a lot of money to be made in the clean energy market. Podcast produced by David Levin. Interview by Doug Hamilton. NOVA is produced by WGBH in Boston.
