En Som Energia, con la implementación del Decidim, hemos generado un espacio más amable de participación. Estrenamos la herramienta en 2018, albergando la Asamblea General de la Cooperativa y meses más tarde, hemos llevado a debate el Rediseño de Imagen y la elaboración colaborativa de la Escuela de Som Energia, entre otros procesos de participación. En pocos meses se han registrado más de 3.500 personas participantes, 5 procesos participativos, 3 asambleas funcionando y más de 1.300 votos en la última consulta de la Asamblea General.

Gracias a Decidim, hemos conseguido en Barcelona coproducir un plan estratégico de ciudad conjuntamente con la ciudadanía. En el 2016 inauguramos el Plan de Acción Municipal en forma de proceso participativo a través de Decidim Barcelona. Actualmente dicho plan recoge casi 7 mil propuestas ciudadanas. Una de las ventajas de utilizar esta plataforma es que puedes seguir en todo momento el estado de implementación de las propuestas aceptadas.
