Featured interview: IEA Exec. Dir. Fatih Birol

According to a new report by the International Energy Agency (IEA), global investment in clean energy is on course to rise to $1.7 trillion this year. In fact, investment in solar power is set to exceed oil for the first time ever. But there's still major concern about the unevenness of that growth. The IEA points out that more than 90% of that increase comes from advanced economies and China. Joining Julia to discuss is IEA Executive Director Fatih Birol.  Also on today's show: World Bank President David Malpass, who's stepping down on June 30 after serving more than four years.  To learn more about how CNN protects listener privacy, visit cnn.com/privacy Learn more about your ad choices.
