Section outline

  • Throughout Europe, Renewable Energy Communities have emerged as powerful models of local initiative, resilience, and innovation. While each is shaped by its unique legal, cultural, and geographical context, successful RECs tend to share certain core principles: they start with a strong local commitment, combine technical and social innovation, and put people—not profits—at the heart of the energy system. This section presents three leading examples of best practice, offering inspiration for what is possible when communities are given the tools and space to lead.

      • REScoop.be (Belgium): Building a Federation of Cooperatives

        In Belgium, REScoop.be serves as the national federation of renewable energy cooperatives. Rather than centralizing control, each cooperative remains autonomous while collaborating through the network to share tools, experience, and investment opportunities. This model of “federated cooperation” allows communities to retain local ownership while benefiting from economies of scale and shared learning.

        By creating a platform where energy co-ops can support one another, REScoop.be has helped make Belgium a leader in citizen energy. The lesson is clear: RECs don’t need to grow by scaling up—they can grow by linking across, creating strong networks rooted in local identity and shared values.

      • Som Energia (Spain): Energy Democracy in Practice

        Founded in Catalonia in 2010, Som Energia has grown into one of Europe’s most emblematic citizen-led energy cooperatives. With over 85,000 members, it supplies green electricity across Spain, develops solar and biogas installations, and reinvests profits into new community projects.

        Key to its success is the cooperative’s emphasis on energy democracy. Members participate directly in governance, and transparency is built into every level of decision-making. Som Energia also invests in communication tools and training to ensure that members remain informed and engaged. In doing so, it has become more than a service provider—it has become a movement for energy justice and citizen empowerment.

      • CleanWatts (Portugal): Digital Tools for Local Energy Sharing

        In Portugal, CleanWatts has taken a more technology-driven approach to RECs. Its focus is on developing smart software that allows community members to track, manage, and share energy in real time. By providing intuitive interfaces for households and municipalities, CleanWatts makes it easier for communities to participate in collective self-consumption and local energy trading.

        Digital innovation can often feel abstract or exclusive. CleanWatts challenges this notion by using technology to make energy use visible, understandable, and actionable. The result is not just smarter energy management, but deeper community participation—especially among younger, digitally engaged users.

      • What Do These Initiatives Have in Common?

        Despite their differences, these best practices share some key characteristics:

        • They started small, often with a single pilot project.
        • They built trust through openness, inclusiveness, and transparency.
        • They combined technical solutions with a strong community narrative.
        • They created mechanisms for learning and adapting—either by federating, innovating, or reinvesting.

        Each shows that there is no one-size-fits-all model—but there are values and strategies that travel well across borders.

      • Principles for Success

        If you’re thinking of starting or supporting a REC, consider these guiding principles:

        • Start where you are – begin with what’s feasible and familiar.
        • Engage early and often – people need to feel heard and included.
        • Prioritize the public good – put social and environmental benefit first.
        • Be transparent – governance must be accountable and participatory.
        • Share what you learn – help others grow by telling your story.
