The World Sustainable Energy Days, the largest annual conference in this field in Europe, offer a unique combination of events on sustainable energy production and use, covering energy efficiency and renewable energy sources for buildings, industry and transport. 

Four conferences - which present the latest technology trends, outstanding examples and European strategies - and the "Energiesparmesse", an important energy exhibition, offer ideal opportunities to establish new partnerships. The conference makes an important contribution to awareness raising for green energy and energy efficiency.

Since 15 years, experts and decision makers from all over the world flock to Upper Austria to attend the events - in 2006, the conference attracted more than 930 participants from 56 countries.
