A Supply Curve Of Conserved Energy For Automobiles

This report analyzes the cost effectiveness of automobile fuel economy technologies and the fuel savings that could result from their widespread use in the U.S. automobile fleet. Estimates are derived for the years 2000 and 2010. The technologies analyzed here do not exhaust the list of technologies that may be available for improving fuel economy. This is especially true for the 2010 estimates. If policies to push fuel economy to substantially higher than current levels are enacted, or if fuel prices rise substantially, many more new fuel economy technologies than analyzed here will surely be developed. This analysis thus represents the technological potential for a limited list of technologies that are relatively well understood. Supply curves of conserved energy are developed to illustrate the results of the analysis.
