Welcome to the webpage of the 43nd edition of the International Energy Workshop (IEW), which was hosted by the Research Institute of Innovative Technology for the Earth (RITE) in Nara, Japan, on 11-14 June, 2025.

About the Conference

The IEW is a leading conference for the international energy modelling community. In a world of environmental and economic constraints, energy modelling is an increasingly important tool for addressing the complexity of energy planning and policy making. The IEW provides a venue for scholars and researchers to compare modelling tools, to discuss modelling advances for emerging energy sector issues, and to observe new trends in the global energy sector.

The IEW features plenary sessions and parallel sessions. We invite six keynote speakers. During the parallel sessions around 150 papers were presented. The call for papers was closed on February 1st, 2025. The selected papers covered a range of topics.

IEA-ETSAP workshop (9-10 June) and training course (11-13 June) will take place at the Todaiji Culture Center in Nara. Please see the detail at https://iea-etsap.org/index.php/etsap-meeting
A separate registration to the IEA-ETSAP events will be possible via the web page given above.
