Clean Tech Nation (start time: 4:57): Over the last few years renewable electricity generation has doubled, thanks in part to President Obama’s 2009 stimulus package. In fact, many clean technologies and industries have taken off, including solar, biofuels, green building and electric vehicles. But the stimulus money is about to run out, as is the production tax credit for wind development. To make sense of the current status of and future prospects for clean tech, co-host Susan Moran interviews Clint Wilder, co-author (along with Ron Pernick,) Clean Tech Nation: How the U.S. Can Lead in the New Global Economy.

Wilder and Pernick run Clean Edge, a clean-tech research and advisory firm.

hay — Dr. William Hay of the University of Colorado in Boulder.

Feedback in Climate Models (start time: 14:00): We are witnesses to unprecedented changes to the earth. Great storms and melting ice caps. Scientists say these events are related to the carbon we are dumping into the atmosphere. But even the scientists are stunned by the speed and scale of melting sea ice and ice caps and sea-level rise. Dr. Bill Hay, professor emeritus of geology at CU-Boulder, talks with us about why scientists haven’t been able to keep up with mother nature.
