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.

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.

Was wir schätzen ist, dass es unter dem Gesichtspunkt der Demokratie aufgebaut ist und daher die Demokratie ein großes Anliegen ist. Demokratische Grundsätze wie Rechenschaftspflicht, Gleichheit und Transparenz stehen im Mittelpunkt des Entwurfs.
