Abstract: The transition towards distributed low-carbon energy systems coincides with the introduction and materialization of renewable energy technologies (RETs) and associated infrastructures at the local level and implies a complex re-organization of the territories and a careful consideration of the relationship between energy sources and technologies and the local scale. Indeed, the design and effective implementation of energy policies and technologies require engaging multiple actors across scales in identifying measures ideally fitting with the given political, socio-cultural, economic and territorial contexts, building the acceptability and support of diverse publics.
Social research on social acceptance of RETs and associated infrastructures has grown in the last decades proposing several conceptual frameworks. However, this literature still presents some limitations, such as the scarcity of studies on social acceptance of the whole energy system change instead of single technologies/projects. Moreover, studies often rely and focus only on a single level or dimension of social acceptance, notably community acceptance at the local level, or political and socio-economic acceptance at the national level. Thus, studies integrating market, socio-political and community aspects or triangulating/combining findings from different levels are limited.
This thesis presents a longitudinal and multi-scalar investigation of public discourse and stakeholders’ perspectives on energy policies and technologies in the Marche region (Italy) by connecting public and institutional arenas. The research adopts Social Representations, Justice and Identity Theories and a discursive analytical approach to investigate public engagement and social acceptability in energy system change. The research consists of three studies: a longitudinal discourse analysis of the public sphere (2011-2017), involving document materials and naturalistic data (i.e. local media, political and public debates) to examine the historicity and territorialisation of RETs and related people’s responses; an analysis of public consultations and environmental assessments' reports (2015-2016) regarding the regional energy plan 2020 and twenty-two narrative interviews (2017-2018) with key informants and actors operating at different scales (i.e. policy, market, expert and civil society actors).
The first study shows that people opposition to the territorialisation of RETs were motivated by different factors involving procedural (engagement, authorisation, regulation, guidelines, and assessment in RET deployment), distributional (environmental and social impacts, fit with place materiality and symbolic meanings, distribution of costs and benefits between places and actors) and recognition elements of justice (recognition and treatment of local communities and authorities).
Moreover, the study found that different RETs are conceptualized as strongly intertwined, considering the distributed generation of RETs as a physical aggression and multiplication of impacts devastating the territory. Territorial features and memories of unsustainable economies (overbuilding and soil consumption, widespread industries and pollution, landscape disruption) played a great role in public conceptualization of and responses to RETs considered as aggravating environmental criticalities, putting at risk local economies based on agriculture and tourism and reinforcing distrust toward firms and politics.
To face this situation, the Regional Government started a re-configuration process with the elaboration of energy and environmental policies by means of preliminary and inclusive participation. Despite the institutional participatory pathways have addressed many critical issues, enhancing the timely recognition and inclusion of different normative appraisals in planning and decision-making, and enhancing the overall quality and legitimacy of the plan, this remains constrained by different factors constraining the potential for a sustainable and effective implementation of the strategy and undermining socio-political, economic, and community acceptance.
The findings are discussed in light of the theoretical, methodological and applied (policy) implications of the research on social acceptance and deliberative governance.
