World Sustainable Energy Days 2025

Competitive, collective, climate-neutral!

Staying on target for climate neutrality is a key challenge in changing political and economic frameworks. The aim is clear: no more fossil fuels! Becoming the first climate-neutral continent will offer Europe a key competitive advantage and increase our resilience in all sectors.

In 2025, the World Sustainable Energy Days (WSED) showed how to gain momentum and present policies, programmes and innovation to reach our goals together.

The World Sustainable Energy Days (WSED) are a leading annual conference on the energy transition and climate neutrality with over 650 participants from more than 60 countries.
