World Sustainable Energy Days 2021

Boosting economic recovery with energy efficiency – this is the focus of the WSED 2021.

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!

  • business actors engaged in the energy transition: technology and equipment companies, energy companies, service providers, planners, developers, financing community etc.
  • the energy research community
  • public body representatives (e.g. EU institutions, national, regional and local governments, energy agencies)
  • over 600 experts from more than 60 countries each year!
