Workshops, recreational activities, in-person exhibitions, and digital resources on self-consumption with solar panels, energetic rehabilitation of buildings, energy certification, charging infrastructure for electric vehicles, and many other related topics flood the months of June and July during the European Sustainable Energy Week in different municipalities of Catalonia. The campaign, an initiative of the European Commission with the objective of promoting energy efficiency and renewable energies in the European Union, opens a period of reflection to rethink our relationship with energy. Conferences, workshops, visits to facilities, competitions, and all kinds of activities are organized throughout Europe and are open to the general public, and are also aimed at energy sector professionals, authorities, companies, and NGOs, among others.
