System for the Analysis of Global Energy Markets (SAGE)

The System for the Analysis of Global Energy Markets (SAGE) is an optimizing, technology-rich model used for international policy analysis, which was used to produce energy consumption forecasts through 2030 for EIA's International Energy Outlook for IEO05 and IEO06. For each of 16 regions of the world, it estimates 42 end-use energy service demands based on economic and demographic projections. Projections of energy consumption to meet the energy demands are estimated based on each region's existing energy use patterns, the existing stock of energy-using equipment, and the characteristics of available new technologies, as well as new sources of primary energy supply. Period by period market simulations aim to provide each region's energy services at minimum costs by simultaneously making end-use equipment and primary energy supply decisions. SAGE is part of the Markal family of models, an energy economic linear programming modeling system.
