The 4th International Sustainable Energy Conference – 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.
