Because transportation is so heavily dependent on petroleum fuels, it is at the center of the u.s. energy security issue and is a significant factor in greenhouse gas concerns. Many aspects of these driving forces act in parallel, and addressing them can yield benefits in all three areas. This feature reviews the directions that might be taken by ite in utilizing its expertise and unique position to help achieve a triple-win. The present economic situation in the United States is buffeted by sharp downturns in consumer demand and housing values. At least in part, this was precipitated by the energy shocks of 2007 and 2008, with fuel costs crossing $3 per gallon in 2007 and then $4 per gallon by mid-2008. Beyond cost, there is concern about the integrity of future supplies of petroleum fuels and the nation's energy security in an uncertain world. At the same time, there is growing worldwide concern for the effects of burning carbon-based fuels and the greenhouse gas (GHG) emissions they produce. At the nexus of these three intersecting concerns are the possibilities for a win, win, win situation. Many aspects of these driving forces act in parallel, and addressing them can yield benefits in all three areas.
