For George Shultz, former U.S. secretary of state, clean energy is more than a policy issue. It's personal. That's one reason he drives an all-electric Nissan Leaf powered by solar panels on his home rooftop. "You've got to walk the talk," says Shultz, who leads the Shultz-Stephenson Task Force on Energy Policy at Stanford's Hoover Institution. He is particularly concerned about the impact of global warming on the lives of his great-grandchildren. "I've got to do what I can to see that they have a decent world," he says.
