The EU Sustainable Energy Week (EUSEW) is a month-long series of activities to build a secure energy future for Europe. It brings together public authorities, private companies, NGOs and consumers to promote initiatives to save energy and move towards renewables for clean, secure and efficient power.

Launched in 2006 by the European Commission, the EUSEW was organised by the Executive Agency for Small and Medium-sized Enterprises (EASME) until 2021, and from 2021 will be organised by the European Climate, Infrastructure and Environment Executive Agency (CINEA), in close cooperation with Directorate-General for Energy.

The EU Sustainable Energy Week (EUSEW) will take place on 25-29 October 2021 under the theme: ‘Towards 2030: Reshaping the European Energy System’.
