The European Climate, Infrastructure and Environment Executive Agency (CINEA) is organising the 20th edition of EU’s flagship event for clean energy and renewables, the European Sustainable Energy Week. 

The 20th edition of European Sustainable Energy Week (EUSEW) will take place on 9-11 June 2026 in Brussels and online, under the overarching theme of ‘A clean, secure and competitive Energy Union’.   

The European Sustainable Energy Week is the biggest annual event dedicated to renewables and efficient energy use in Europe, and it features a 3-day Policy Conference, the EUSEW Awards ceremony, as well as networking opportunities at the Energy Fair, celebrating the people, projects, and initiatives advancing Europe’s transition to clean and sustainable energy.  During the conference, youth voices are put forward through the Young Energy Ambassadors and the European Youth Energy Day. Last but not least, the Sustainable Energy Days give visibility to and foster clean energy solutions in the EU and around the world, from March to June 2026.
