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...

In this paper, we introduce the combination of an energy-process model with the geometric distributed lag demand, called the energy-GDL process model, as well as its solution technique. In an energy-GDL process model, the demand is represented by a function of the prices not only in the current...

The Waterloo Energy Modelling System (WATEMS) is a spreadsheet-based tool for the creation and maintenance of mathematical programming models of energy supplies and demands. Unlike the approach of general purpose matrix generators, WATEMS restricts the modeller to network constraints and just a...

We discuss a model that involves the use of linear programming to calculate the least costly configuration of the energy system in the province of Ontario in Canada for the year 2021. We identify some desirable changes in energy technologies and fuels, compared with the present, and we analyze...
