The Energy Union and the European Green Deal advocate the participation of citizens and communities in the energy transition, which encourages a bottom-up approach in the implementation of sustainable energy initiatives. Both are in tune with the United Nations' Sustainable Development Goals, which attempt to involve all members of society in the sustainability path. The reality in EU member states, however, is that community energy still lacks the necessary regulatory framework to compete with large utility companies. This may indicate that the governance framework is lagging behind, still not ready to include communities (collective citizens) as full participants in the energy transition. KEYWORDS citizens' ownership; community renewable energy; co-operatives; energy citizenship; sustainable energy transitionThe European Green Deal (EGD) claims to be "for the E[uropean] U[nion] and its citizens", as well as a "transition" that should be "just and inclusive" (EC 2019a, 2). This wording is important, as it is trying to address, in a post-Brexit and Eurosceptic context, the issues related to the democratic deficit, legitimacy and citizenship in the EU, which the Treaty of Lisbon attempted to correct in 2007, but still have been widely highlighted in the literature for many years (for example Katz 2001).An important element of the sustainable transition is that of energy systems. In the EU, environmental protection, sustainability or climate change are approached in a more integrative manner, since they are generally accepted as issues that need to be globally addressed, and enjoy wide (and increasing) public support (EC 2019b). These topics have been on the political agenda of the EU for decades: environmental policies have been in place since the 1960s, with diverse attempts to integrate said policies with energy-related ones (see, for example, Dupont and Primova 2011). Energy policy, however, has traditionally been a very complex area for the EU (Herranz-Surrallés et al. 2020; IEA 2020). Numerous regulatory changes have failed to achieve enough market integration and liberalisation to bring down the cost of energy for consumers.The purpose of this article is to address the question: What are the drivers and barriers for the implementation and success of community renewable energy projects in the EU? It aims to inform the debate about the role of these actors in a sustainable energy transition as part of an overall sustainable transition in Europe.
