World Sustainable Energy Days

  • When: 05 Mar - 08 Mar 2024

Energy transition now – fast, smart, resilient! This is the motto of the next World Sustainable Energy Days (WSED) from 5 - 8 March 2024 in Wels/Austria – a leading international conference and tradeshow on achieving climate neutrality that attracts 600+ participants from more than 60 countries each year.
