Mettre en espace la transition. Retour sur la construction d’un dispositif participatif pour la planification énergétique territoriale

Résumé :

La stratégie nationale en matière de transition énergétique prévoit d’atteindre la neutralité carbone en 2050. La forte conflictualité qui accompagne l’inscription spatiale de la transition invite à repenser les modes de participation publique aux décisions relatives à la gouvernance territoriale de l’énergie. La planification énergétique, en tant qu’outil de construction d’un projet territorial cohérent, pourrait ainsi devenir un levier de démocratisation des politiques publiques de transition. Cet article explore cette hypothèse à travers l’étude ethnographique de la construction d’un dispositif participatif au sein d’un PETR (Pôle d’équilibre territorial et rural) de 80 000 habitants. L’objectif était d’associer les habitants à la spatialisation des objectifs énergétiques définis dans son PCAET. L’analyse s’appuie sur des observations et entretiens menés durant un processus encore en cours au moment de la rédaction de cet article ; il s’agit donc de restituer des points d’arbitrage ayant émergé entre les acteurs engagés dans le projet. Trois enjeux majeurs émergent. D’abord, la planification spatiale est soumise à des contraintes multiples, limitant les marges de manœuvre des collectivités. Ensuite, l’étroitesse de ces marges de manœuvre implique une difficulté sur le sens à donner à la participation : comment proposer un dispositif qui offre un réel débouché politique, concret et compréhensible, à l’engagement des habitants ? Enfin, l’ampleur des efforts requis (production d’EnR, réduction des consommations) complique l’appropriation par les individus de la planification à l’échelle territoriale. Notre enquête révèle ainsi un paradoxe : la planification énergétique participative vise à prévenir les conflits locaux en impliquant les habitants dans la définition des trajectoires de transition, mais les marges de manœuvre restreintes et l’ampleur des défis tendent à réduire la participation à un exercice de sensibilisation, voire d’acceptation d’une réalité subie.

Résumé en anglais :

France’s national energy transition strategy aims to achieve carbon neutrality by 2050. This target requires both ambitious reductions in energy consumption and a significant increase in renewable energy production. These objectives are set within a context of decentralized public energy action, placing local authorities at the heart of a dual challenge: technical (how to consume and produce energy sustainably at the territorial level?) and democratic (how to conduct the transition in a way that is perceived as legitimate by residents?). The high level of conflict surrounding the spatial implementation of the transition—particularly the deployment of renewable energy infrastructure—calls for a rethinking of public participation in decisions related to territorial energy governance. In this context, energy planning (notably through the development of documents such as the Territorial Climate-Air-Energy Plans, PCAET) can be seen as a privileged space for democratizing public policies on energy transition. As a comprehensive and coherent territorial project, energy planning offers an opportunity to engage residents in the democratic shaping of these policies. This article explores this hypothesis by presenting an ethnographic study of the construction of a participatory device designed to involve residents of a Pôle d’Équilibre Territorial et Rural (PETR) with 80,000 inhabitants in spatializing the energy objectives defined in its PCAET. As a member of the TEPOS network (Territories with Positive Energy), the PETR aims to meet its energy needs through local renewable sources. The device under study centers on a digital platform inviting contributors to propose actions for mapping, on a territorial map, the community’s targets for renewable energy production and consumption management. Our analysis draws on observations and interviews conducted during an ongoing process at the time of writing. Rather than describing the final state of the device as envisioned by its promoters, we focus on key points of arbitration that emerged among the actors involved—points that reveal the inherent difficulties of democratizing energy planning issues. First, it appears that the spatial planning exercise itself (whether participatory or not) is subject to strong constraints of various kinds (regulatory, budgetary, political, and material), which limit the community’s room for maneuver in achieving its TEPOS objectives. Second, the narrowness of this room for maneuver raises questions about the meaning of participation: how can a device be designed that offers residents a real, concrete, and understandable political outlet for their engagement? Third, the massive scale of the efforts required (in terms of renewable energy production and consumption reduction) makes it difficult for individuals to grasp planning at the territorial level. Our investigation ultimately suggests—and this is its main finding—that the very idea of participatory energy planning faces a paradox: while its purpose is to prevent local conflicts over renewable energy infrastructure by involving residents in defining the energy transition at the territorial level, the limited room for maneuver of local authorities, combined with the massive scale of the efforts required, tends to reduce participation to an exercise in raising awareness or acculturating residents to a reality that is imposed upon them.
