WATEMS-GDL is an energy-modelling system designed for the easy construction and updating of energy-planning models of the mathematical programming type. This paper describes the development of WWW-WATEMS-GDL, based on WATEMS-GDL. WATEMS-GDL users can use WWW-WATEMS-GDL to put their energy models...

Undesirable output-oriented Data Envelopment Analysis (DEA) models with different return of scales are used to study the CO2 (Carbon dioxide) emissions performance of the transport sector throughout China's 30 administrative regions. Empirical results show that the number of efficient regions...

In this paper, an energy-process model with geometric distributed lag (GDL) demand, called the energy-GDL process model, is updated to aid in energy-related CO2 emission control policy analysis. The updated model was formulated, constructed and solved with the updated GDL version of the Waterloo...

As one of the three high-energy consumption sectors (industry, building, and transportation) in China, the transport sector faced a devastating resource and environment challenge. The transport sector was reportedly responsible for about 15.9% of the country’s total final energy consumption in...

Energy end-use for all sectors (commercial, residential, transport, industrial) in Hong Kong shows that the residential share increased from 14.2% in 1990 to 18.1% in 2007, such share increase has prompted the authors to analyze the issue. The Divisia decomposition analysis is used to evaluate...
