What are the World Sustainable Energy Days (WSED)?


Europe has the ambitious goal of becoming the first climate neutral continent by 2050. The Green Deal and the EU Climate Law are first concrete steps. The current economic challenges are also an opportunity to accelerate decarbonisation and to create a fairer society and a more competitive economy.


In 2021, the conference - which attracts over 600 participants from over 60 countries each year - shows how we can make a green recovery happen in practice and how the energy transition can contribute as an investment engine to this deep transformation.




Our audience: the entire energy transition world!
