Multifaceted energy systems
Accelerating coordinated action across governments, the energy industry and industry sectors to enable the new multifaceted energy system.
Europe's leading energy transition event will return to Lisbon, Portugal
Endorsed by the Ministry of Environment and Energy, the Lisbon Energy Summit & Exhibition 2025, the Iberian region's leading energy transition event, will welcome over 2,000 visitors to Lisbon, Portugal, a world leader in new energies and technological innovation, on 3 – 4 June 2025.
Ministers, policymakers, project developers, investors and innovators will engage at a 2-day high-level strategic conference sharing insights into transitioning the E.U.’s energy system to one based on renewables and in line with the REPowerEU initiatives. Showcased across the exhibition's hydrogen & decarbonisation, solar and innovation zones are the products and projects that will deliver this cleaner, greener energy system.
Join the international exhibition as a visitor, or book your delegate pass to access the Strategic, Hydrogen & Decarbonisation and Climatetech conferences.
