Energy modeling
 | This technology-related article is a stub. You can help Wikipedia by expanding it. |
Energy modeling and energy system modeling refer to the process of building computer models of energy systems in order to analyze them. Such models often employ scenario analysis to investigate different assumptions about the technical and economic conditions at play. Outputs may include system feasibility, greenhouse gas emissions, financial costs, and energy efficiency of the system under investigation. A wide range of techniques are used, ranging from broadly economic to broadly engineering. Mathematical optimization is often employed. Models may be international, regional, national, or local in scope, with governments often maintaining national models for national energy policy development.
Model types
