ISEC 2026 – CONFERENCE
FOR RENEWABLE HEATING AND COOLING IN INTEGRATED URBAN AND INDUSTRIAL ENERGY SYSTEMS
The 4th International Sustainable Energy Conference – ISEC 2026 brings together researchers, industry leaders, and energy policymakers from around the world to contribute their latest findings, innovations, and demonstrations toward a sustainable energy future.
ISEC 2026 will focus on the key 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 economic systems toward 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 a driver of forward-thinking concepts, ISEC 2026 aims to promote groundbreaking ideas for the heat transition in renewable energy systems and the improvement of resource efficiency. The conference fosters an in-depth exchange between research, industry, and policymaking.
In collaboration with key international organizations such as UNIDO and IEA, the event will also place special emphasis on solutions for developing and emerging economies, particularly in the Global South.
What to expect:
High-level keynote speakers, presentations, poster sessions, workshops, and intensive discussions.
ISEC serves as a catalyst for new collaborations and transformative projects that support the phase-out of fossil fuel-based energy systems.
