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....

This paper introduces a new method to estimate and decompose sources of carbon dioxide emissions using the input–output model. This method uses what we call the ‘mean rate-of-change index’ for weights of the decomposed terms. In this journal, Ang et al. asserted that logarithmic mean...

We present the findings of a literature survey on decision analysis in energy and environmental modeling. Surveyed studies are classified according to the decision analysis technique used and by application area. It has been found that decision making under uncertainty is the most important...

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...

Four interfuel substitution processes (ISPs) are modeled using growth curves based on the data for Southeast Asian countries. Income and price variables are incorporated in the models so that an ISP can be viewed in the context of a cause and effect system responding to the changes in the...

We present a method for decomposing industrial energy demand using the Divisia approach. This method involves decomposition of the aggregate energy-intensity index measured in terms of energy consumption per unit output. The factors considered are changes in production structure and sectoral...

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...
