Open Calls for the European Energy Efficiency conference 2027

OÖ Energiesparverband(ESV), organiser of the World Sustainable Energy Days (WSED), is inviting papers and speakers for the European Energy Efficiency Conference 2027 edition, taking place from 3 to 5 March in Wels, Austria. Researchers, practitioners and experts are invited to share their work, projects and insights with the wider sustainable energy community.

The conference is built around one idea: energy efficiency is the fastest, most cost-effective and lowest-risk way to keep Europe's energy supply affordable, secure and sustainable. It brings together businesses, public authorities, researchers and policymakers working across the sector, from technical solutions to policy and financing.
