BRIEFING: TRANSPORTATION BRIEFING 60 TECHNOLOGY REVIEW NOVEMBER /DECEMBER 2009 F or the next few decades at least, liquid hydrocarbons—gasoline, diesel, and jet fuel—will continue to be the mainstays of transportation. They’re cheap; refueling is fast; and their energy density, crucial to long- distance travel, is hard to beat. “Advanced technology is going to happen slowly,” says Daniel Sperling, the director of the Institute for Transportation Studies at the University of California at Davis and a mem- ber of the California Air Resources Board. “The focus needs to be on making conven- tional technology more effi cient.” It should be possible to reduce the fuel consumption of a midsize sedan by up to 60 percent without sacrifi cing size or perfor- mance, using mostly existing technology. Lightweight materials will help. Advanced turbocharging and fuel-injection technol- ogy will extract more power from smaller engines that lose less energy to friction (see “Research to Watch,” p. 69) . Similarly, making airplanes lighter and their engines more effi - cient could cut their fuel consumption 30 to 50 percent by 2020. Biofuels should help curb petroleum con- sumption, although the contribution they make will depend on many factors, includ- ing the price of oil and the development of new technologies. The International Energy Agency has estimated that by 2050, etha- nol and biodiesel could meet 13 percent of global demand for transport fuel. The U.S. Energy Information Administration estimates that biofuel consumption in the United States will increase from 7.7 billion gallons per year in 2007 to 35 billion gallons by 2030 while consumption of gasoline, diesel, TECHNOLOGY OVERVIEW Petroleum’s Long Good-bye ±.3 kilograms
