The potential effect of future energy-efficiency and emissions-improving technologies on fuel consumption of heavy trucks.

Researchers at Argonne National Laboratory analyzed heavy-duty truck technologies to support the Energy Information Administration's long-term energy use projections. Researchers conducted an analysis of several technology options that have potential to improve heavy truck fuel economy and emissions characteristics. The technologies are grouped as fuel-economy-enhancing and emissions-improving. Each technology's potential impact on heavy truck fuel economy has been estimated, as has the cost of implementation. The extent of technology penetration is estimated on the basis of truck data analyses and technical judgment

A Summary of Truck Fuel-Saving Measures Developed With Industry Participation

This report describes the third project undertaken by the Center for Transportation Research, Argonne National Laboratory (ANL), in a US Department of Energy program designed to develop and distribute compendiums of measures for saving transportation fuel. A matrix, or chart, of more than 60 fuel-saving measures was developed by ANL and refined with the assistance of trucking industry operators and researchers at an industry coordination meeting held in August 1982. The first two projects used similar meetings to refine matrices developed for the international maritime and US railroad industries. The consensus reached by those at the meeting was that the single most important element in a truck fuel-efficiency improvement program is the human element -- namely the development of strong motivation among truck drivers to save fuel. The role of the driver is crucial to the successful use of fuel-saving equipment and operating procedures. Identical conclusions were reached in the earlier maritime and rail meetings, thus providing a strong indication of the pervasive importance of the human element in energy-efficient transportation systems. The number and variety of changes made to the matrix are also delineated, including addition and deletion of various options and revisions of fuel-saving estimates, payback period estimates, and remarks concerning items such as the advantages, disadvantages, and cautions associated with various measures. The quality and quantity of the suggested changes demonstrate the considerable value of using a forum of industry operators and researchers to refine research data that are intended for practical application

Current emission trends for nitrogen oxides, sulfur dioxide, and volatile organic compounds by month and state: Methodology and results

This report presents estimates of monthly sulfur dioxide (SO{sub 2}), nitrogen oxides (NO{sub x}), and nonmethane voltatile organic compound (VOC) emissions by sector, region, and state in the contiguous United States for the years 1975 through 1988. This work has been funded as part of the National Acid Precipitation Assessment Program's Emissions and Controls Task Group by the US Department of Energy (DOE) Office of Fossil Energy (FE).

Performing physiocracy: Pierre Samuel Du Pont de Nemours and the limits of political engineering

The story of Pierre Samuel Du Pont de Nemours has often been described as one of success. The man was a well-known statesman, economist and entrepreneur in late eighteenth-century France and his main legacy, the famous and still thriving Du Pont company, suggests a brilliant trajectory. The aim of this paper, however, is to analyze Du Pont's failure in performing the political and economic doctrine of which he was an active promoter all through his life: physiocracy. In all of his very diverse activities, be they scientific, political, or entrepreneurial, Du Pont indeed deliberately attempted to enact this original liberal doctrine. He tried, along with fellow physiocrats, to introduce freedom of trade and enterprise in Old Regime French minds and economic practices. Later, when emigrating to the United States, he devised a plan for a physiocratic colony. But none of these ventures was actually a success during Du Pont's lifetime: the performation of some of physiocracy's main propositions only came later, in a diffuse and partial way. We contend that this relative failure of performativity can be explained by Du Pont's specific type of agency: one relying mainly on political engineering, based on personal ties and reputations, as well as on a strict distinction between ends and means
