Abstract:Auto production and operation consume energy, material, capital and labor resources. Numerous substitution possibilities exist within and between resource sectors, corresponding to the broad spectrum of potential design technologies. Alternative auto design concepts are examined in terms of their aggregate resource impacts. A computer-based model has been developed for generating the resource requirements of alternative automobile technologies. The model goes beyond previous tools in its scope, level of impact disaggregation, and flexibility. It projects the annual energy, material, capital, and labor requirements of the passenger-automobile fleet through the year 2000. The methodology integrates a family-tree technique for material and energy accounting, with an input-output approach which generates the capital and labor information. Twenty-four major materials are tracked, with supply disaggregated among primary and recycled materials, imports, and domestic sources. Net energy consumption is derived, along with capital and labor impacts disaggregated by 90 industries. The Resource Accounting methodology is described, with emphasis on the Fleet Attributes Model. Representative results are presented and discussed.
