Energy modeling applications for analysis of policy options-an overview

The paper reviews the complex relationships of the elements of a national energy system and the integrated energy planning approach that can be inevitably implemented through computer based modeling tools. General format of an IEP model and its main modules have been described and typical examples of energy models developed and used in different countries have been quoted to show the world-wide application of energy models for policy planning. Energy modeling tools and representative E3-models, that offer capacity building opportunities to the developing nations, have been described.
