Economic, environmental and energy life cycle inventory of automotive fuels

摘要

There is an ongoing debate as to what fuel or fuels should power automobiles. Many analysts look at economics, others look at criteria pollutants, still others make the case based on carbon dioxide and other greenhouse gases embodied in the fuel. This study utilizes life cycle inventory techniques to examine the economics, emissions and energy efficiency of automotive fuels as a means to improve the energy utilization efficiency and to better protect the environment. Application of the techniques demonstrates the trade-offs inherent in substitute fuels.
