Scenario Analysis by Energy Model

Many computational energy models have been internationally developed to analyze energy supply and demand for the purpose of assessing the specific impact of energy and environmental policies. Energy models are utilized for a wide range of requirements such as energy price impact assessment, energy policy impact assessment such as the introduction of advanced technology and infrastructure, feasibility analysis of greenhouse gas emission reduction such as carbon neutrality, and creation of a realistic future energy supply and demand outlook. The merits of the energy model consist of consistent and quantitative evaluation of numerous factors using mathematical formulas for a system with a huge and complex structure such as energy and economy, deep understanding of the system structure through modeling, and provision of a transparent framework for policy discussions. Future energy model directions include expanding and refining the types of target technologies and sectors, and refining geographical and temporal resolutions in light of computational performance improvements. © 2022 The Institute of Electrical Engineers of Japan.
