EUSEW is the first major initiative organised by the European Institutions in collaboration with a wide range of private and public organisations. The EUSEW also reflects the active cooperation between several key EU initiatives managed by the European Commission, including Concerto +, Civitas Forum, ManagEnergy, EPBD Buildings Platform, the Intelligent Energy - Europe Programme, the Sustainable Energy Europe Campaign, and the European Technology platforms for Photovoltaics and Solar Thermal. EUSEW is organised under the auspices of the overall Sustainable Energy Europe Campaign (SEE). The events that took place during this first EUSEW covered key topics, highlighting the multi-sectoral nature of sustainable energy development and stressing the need for all stakeholders to work together towards a common goal. The events ranged from conferences, meetings, symposiums and award ceremonies to receptions and exhibitions.
