High and fluctuating gasoline prices are here to stay, says Paul P. Craig, professor emeritus of engineering at UC Davis and an expert in energy policy and conservation. Limits on oil supplies, production and refining capacity mean that uncertainty will dominate the global energy market for the foreseeable future, Craig says. The good news is that governments, businesses and consumers have a strong incentive to get more efficient and begin the inevitable switch to alternative forms of energy. Craig has worked as a physicist and researcher at the Los Alamos and Brookhaven National Laboratories. From 1970-75, he served under the president's science advisor as deputy director and acting director of the Office of Energy R&D Policy at the National Science Foundation. He joined the UC Davis Department of Applied Science in 1975. In 1997, he was appointed by President Clinton to the Nuclear Waste Technical Review Board, reviewing the feasibility of the proposed nuclear waste repository at Yucca Mountain, Nev. He resigned from the board in 2004. He is a member and former chairman of the Sierra Club's National Energy Committee.
