The EUSEW, organised by the Executive Agency for Competitiveness and Innovation (EACI) on behalf of the European Commission's Directorate-General for Energy, will host a high-level policy conference in Brussels from Tuesday, 19 June until Thursday 21 June. Approximately 4 000 people from 50+ countries are expected to attend to take advantage of the opportunity to exchange ideas with other players in the sustainable energy sector, meet EU staff and pursue business opportunities. Also during EUSEW, almost 150 Energy Days will take place in the Belgian capital, as well as 900 across Europe. Aimed at the general public, these events promote energy efficiency and renewable energy sources in an engaging, accessible and interactive way.
