Renewable Energy Communities: Towards a new sustainable model of energy production and sharing.

In the context of Europe's efforts towards decarbonization, this paper introduces a novel framework for Renewable Energy Communities (RECs), validated with multiple case studies from Italy's practice. Drawing on established concepts and an extensive literature review, the framework identifies key pillars supporting its model. The paper delineates the essential features defining the conceptual model of RECs, offering a process-oriented perspective. This model serves as a tool to assess the success of existing RECs comprehensively and provides a structured pathway for the development of new projects across different countries, fostering replication within communities. An overarching framework is presented as a solution to enhance the effective utilization of renewable energy sources. Buildings, and the communities of people who live in them are considered primary energy consumers and direct beneficiaries of a REC framework. Consequently, an original pathway for the mass renovation of buildings located in highly populated areas, from the energy sources perspective, is provided. • A conceptual model of Renewable Energy Communities (RECs) is developed. • Provides a structured pathway for the development of new projects across countries. • Provides a tool to assess the success of existing Renewable Energy Communities. • The model represent a concrete solution for the nearly Zero Energy Building and Zero-Emission Building concepts.
