Mit der Implementierung von Decidim in Som Energia haben wir einen freundlicheren Raum für Partizipation geschaffen. Wir haben das Tool 2018 freigegeben als Gastgeber der Generalversammlung der Genossenschaft und Monate später diskutierten wir das Image Redesign und die gemeinsame Entwicklung der Schule von Som Energia, unter anderen partizipatorischen Prozessen. In wenigen Monaten haben sich mehr als 3.500 Teilnehmer registriert, 5 Beteiligungsprozesse, Bei der letzten Generalversammlung stimmten 3 Versammlungen und mehr als 1.300 Stimmen.

We suffer under a lack of public space. It's particularly important that we reclaim these public spaces for us. Open platforms such as Decidim do exactly that. Is not only that is open source so other people can fork it, reuse it and build a process. It also has these values that we want to reflect in our society encoded in the way it's designed.

The process started in October 2019 at the European Commission’s DG Communication and eDemocracy unit at the Joint Research Centre, the European Commission's science and knowledge service. An analysis of the needs of the Conference and which tools fit those, lead to choosing the open source tool Decidim for its technical maturity, broad community and adaptability.
