World Sustainable Energy Days 2023

"Energy transition = Energy security!" This is the motto of the next World Sustainable Energy Days (WSED) from 28 February - 3 March 2023 in Wels/Austria. 

The price crisis, multiplying signs of climate change and threats to energy security urge us to act like never before. REPowerEU, the new EU initiative, reflects this urgency and provides new momentum for the energy transition.
