World Sustainable Energy Days 2026

 

Energy transition = energy independence


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.

Programme overview 2026

European Pellet Conference, 25 February

Pellets - energy and more! 

With more than 450 participants each year, it is the meeting place for the global pellet community. Leading international speakers present the latest trends in markets, policies, technologies and innovations – helping you stay on top of developments in the pellet and bioenergy world.

Europe must urgently reduce its dependence on fossil fuel imports. Pellets can play an expanding role in this transformation! While facing challenges such as increasing electrification, reluctance to invest or policy uncertainties, opportunities are emerging from new applications such as BECCUS, biochar and biomaterials.

Join us at the 2026 European Pellets Conference to explore how bioenergy is driving decarbonisation, energy security and the circular economy for a climate-neutral Europe.

European Energy Efficiency Conference, 25 - 27 February

Energy efficiency = energy independence

Geopolitical instabilities, high energy prices and growing global competition make one thing clear: Europe must urgently increase its energy independence. Energy efficiency is a key asset in this transformation: It reduces energy demand, stabilises prices and
makes Europe more resilient.

The European Energy Efficiency Conference 2026 presents policies, technologies and business models which increase competitiveness and make energy more affordable.
