Geopolitical instabilities, high energy prices and growing global competition make one thing clear: Europe must urgently increase its energy independence. Energy efficiency and renewable energy are the key assets in this transformation: They decrease energy imports, reduce energy prices and make Europe more resilient.
The World Sustainable Energy Days (WSED) present policies, technologies and business models which increase competitiveness and make energy more affordable. The event is a leading annual conference on the energy transition and climate neutrality with over 650 participants from more than 60 countries.
