This paper consists of three inter-related parts. The first is a survey study on the application of growth curves to energy studies. A description on each of the four identified application areas, namely, energy resource analysis, energy demand modeling, fuel substitution, and energy technology...

We present the results of a factorization analysis of automobile fuel consumption in actual traffic. Three specific studies related, respectively, to trip purpose, road type, and time period of trip generation were carried out. In each study, the variations in vehicle fuel consumption were...

We present the results of a study on process energy use of two asphalt-mixing plants. The production process involves the mixing of granite aggregates and bitumen to give asphalt mixtures. The mixtures are widely used as a road-paving material. A large part of the process energy use is for...
