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.

As an engine for forward-thinking concepts, ISEC 2026 aims to push groundbreaking ideas for the heat transformation in renewable energy systems and improved resource efficiency. The conference fosters a comprehensive exchange between research, industry, and policymaking.
