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 celebrating the people, projects, and initiatives advancing Europe’s transition to clean and sustainable energy; networking opportunities at the Energy Fair. 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.
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 three days will be animated by 50 policy sessions and onsite participants will have the oppotunity to visit the Energy Fair, a platform to showcase activities in the fields of energy efficiency and renewable energy. The 2026 edition will host 28 stands in the European Commission’s Charlemagne building. Discover the organisations involved.
