Conference for
Renewable Heating and Cooling
in Integrated Energy Systems
The 4th International Sustainable Energy Conference will be held in Graz, Austria from 14 to 16 April 2026.
The ISEC 2026 invites researchers, industry leaders, and energy policymakers from around the world to contribute their newest findings, innovations and demonstrations toward a sustainable energy future.
ISEC 2026 will focus on the question: How can we achieve energy sovereignty within a time horizon dictated by climate change and defined by politics?
Global solutions such as the transformation of our economic systems towards a sustainable circular economy, the complete phase-out of fossil fuels, the implementation of sector coupling, energy storage systems, and the smart electrification of the energy supply will be central themes in presentations and discussions.
