38th International Energy Workshop

3-5 June 2019, Paris, France

Register for IEW 2019

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 International Energy Workshop (IEW) is a leading conference for the international energy modelling community, providing a venue for scholars and researchers to compare modelling tools, discuss modelling advances for emerging energy sector issues, and observe new trends in the global energy sector.

International Energy Agency

The 38th edition of the International Energy Workshop (IEW) will be hosted by the International Energy Agency, Paris, France. The International Energy Agency is the global energy authority, providing data, analysis and solutions on all fuels and all technologies; helping governments, industries and citizens to make good energy choices. Through its gold standard modelling tools, the IEA examines the full spectrum of energy issues ranging from medium-term (Market Reports on oil, gas, coal, renewable, energy efficiency) to long-term (World Energy Outlook) as well as looking into technologies (Energy Technology Perspectives) and system integration questions.

Keynote speakers & Plenary session chairs

Dr Fatih Birol (Chair)

Dr Fatih Birol has served as Executive Director of the International Energy Agency since September 2015. He was re-elected in January 2018 for a second four-year term, which will begin in September 2019. Under his leadership, the IEA has undertaken its first comprehensive modernisation programme since its creation in 1974. This effort focuses on three pillars: opening the doors of the IEA to include major emerging countries, such as Brazil, China, India, Indonesia, Mexico and South Africa who have joined the IEA Family, thus increasing its share of global energy demand from 38% to almost 75%; broadening the IEA’s security mandate to natural gas and electricity as well as oil; and making the IEA the global hub for clean energy technologies and energy efficiency.
