Guest: Gwyneth Cravens.

Even the skeptics can be convinced—and need to be, says novelist Gwyneth Cravens. In her book Power to Save the World, she takes an informed look at nuclear energy in order to debunk some of the myths surrounding it. Today on Focus, she'll join us to talk about her findings and her belief that nuclear energy is a completely realistic solution to global warming—possibly even a necessary one.

Guest: Brian Jennings.

The price of oil has driven the rise of ethanol as a potential alternative, but some still remain skeptical, questioning the environmental impact of ethanol production. Today on Focus we'll have the second of two programs looking at the pros and cons of ethanol with guest Brian Jennings, Executive Vice President of the American Coalition for Ethanol.

Guest: Joseph Romm.

In his State of the Union address last year, President Bush called for the development of hydrogen as an energy source. This morning on Focus we'll talk with former Department of Energy official Joseph Romm about whether hydrogen could be powering our world in the near future. Romm says he doubts that hydrogen-powered cars will become available anytime soon—but hydrogen fuel cells could power our homes and businesses. He'll also discuss his recent book, The Hype About Hydrogen.
