World Sustainable Energy Days 2021

The countdown is on! Only 2 weeks left until the World Sustainable Energy Days (WSED) taking place from 21-25 June 2021 in Wels/Austria and online.


Boosting economic recovery with the energy transition is the focus of this year's special edition of the event! After more than a year, it is one of the first international conferences offering online and on-site participation (in full compliance with COVID regulations). Take advantage of this opportunity!


Energy transition ↔ Green recovery!

Europe is aiming for a 55% reduction of CO2 emissions by 2030 as a milestone on its way to climate neutrality by 2050. It is crucial that the investment decisions made in the next few years put us on the path of being "fit for 55" by the end of this decade. The WSED show how we can make a green recovery happen in practice and how renewable energy and energy efficiency can contribute as an investment engine. It presents policies, technologies, markets and more!


A comprehensive package of specialised, complementary events:

  • European Energy Efficiency Conference
  • European Pellet Conference
  • Industrial Energy Efficiency Conference
  • Innovation Workshops: Green Finance, Buildings, Technologies
  • Young Energy Efficiency Researchers Conference
  • Energy Efficiency Policy Conference
  • Smart E-Mobility Conference


Each year, over 600 participants from more than 60 countries attend!


The event is organised by the OÖ Energiesparverband, the Energy Agency of Upper Austria. Upper Austria is a leader region in the energy transition: Greenhouse gas emissions from buildings were reduced by 39% in 10 years. Over 60% of all space heating and 31% of the primary energy already come from renewables.
