Developing Energy Communities through Informative anD collEctive actions

DECIDE is a Horizon 2020 project that aims to gain a better understanding of how energy communities and energy efficiency services are established and managed. It also intends to identify which kind of communications and interactions work best to encourage participation in energy communities for specific types of individuals and groups, and to test and transfer knowledge in pilot projects across Europe. It focuses on three groups of energy communities: those existing at the beginning of the project, those that will be introduced during the project’s process, and those not directly involved in the project but benefiting from it. The three groups will provide complementary and geographically well-spread pilots such as social housing and middle-class and upper-class quarters in Austria, Belgium, Estonia, Germany, Greece, France and the Netherlands.
