Electricity demand forecasting plays an important role in electricity systems expansion planning. In this paper, we present a trigonometric grey prediction approach by combining the traditional grey model GM(1,1) with the trigonometric residual modification technique for forecasting electricity...

We discuss some methodological and application issues related to decomposing national industrial energy consumption into changes associated with aggregate industrial production level, production structure and sectoral energy intensity. Past studies are classified and reviewed with respect to...

A method for estimating non-commercial energy consumption in the household sector of developing countries is presented. It has been observed that the energy demand for cooking is not income-elastic. The average requirement per person and hence the total requirement, both in useful energy terms,...

The energy savings arising from transport and traffic management schemes in Singapore are estimated. These schemes are, respectively, the Additional Registration Fee (ARF) on passenger cars and the Area Traffic Control (ATC) in the central business zone. The ARF was introduced in 1972 and...

The 1995 survey on decision analysis (DA) in energy and environmental modeling by [Huang et al. Decision analysis in energy and environmental modeling. Energy 1995; 20: 843–855] lists 95 publications. We updated the survey and found that the number of publications has almost tripled to 252. We...

We present the results of a study on the effects of maintenance on the fuel efficiencies of a fleet of public buses. We classified maintenance into major, minor, and ineffective based on their expected levels of impact on fuel consumption. The results show a significant improvement in fuel...

We analyze trends in commercial energy consumption, changes in the fuel-mix, and the relation between energy consumption and economic growth in the ASEAN region from 1960 to 1986. The structure of energy demand is examined at the sectoral level to identify systematic variations over time and...

A new energy decomposition method, called the Log-Mean Divisia Index Method I (LMDI I), is presented. It has the desirable properties of perfect decomposition and consistency in aggregation. Perfect decomposition ensures that the decomposition results obtained do not contain a residual term....

We present the results of a statistical study on the effects of the following four operational changes on the fuel consumption of scheduled buses: a change in the brand of engine oil used, a switch from crossply to radial tires, engine overhaul, and vehicle maintenance. This is an empirical...

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...
