European Sustainable Energy Week

The call to register a Sustainable Energy Day is now closed.


Sustainable Energy Days are events that take place anywhere around the world, promoting clean energy and energy efficiency. In the current context of the energy transition and independence of the energy supply, every Sustainable Energy Day is an opportunity to inspire behavioural changes and innovation towards meeting energy and climate goals in the EU and around the world.

These events take place between March and June 2023, exploring a variety of topics in sessions of different formats and durations.

You can be creative! A Sustainable Energy Day event might concentrate on awareness-raising, be centred on a specific activity, or focus on a particular technology or policy. It may choose to address a local community or even an entire region. Sustainable Energy Days can take place in public or private buildings, as well as outdoors or online. Past events took place in locations such as schools, parks, town halls, factories and conference centres.

In the context of the European Year of Skills, events tackling upskilling European citizens for a clean energy transition are particularly encouraged. Get inspired by our tips for organising an impactful event with our dedicated guide.
