The REASONS Chair (Renewable Energy Age : SOcial NoticeS) proposes a comparative analysis of the debate about energy transition technologies ( broadly defined as the technical devices that enable the implementation of an energy transition). The Chair is based on the assumption that the debates are mainly rooted in the lack of common rules to support the transitions; through the analysis of these debates, the Chair intends to identify and understand the implied norms that the debates enable to be implemented. That will be achieved by combining four tasks, plus a governance task. The first task will focus on the way social organizations have positioned themselves in relation to transition technologies, in particular by studying in-depth two dimensions of these debates ( each dimension being the subject of a PhD thesis): the manner in which they attack companies who make false promises, thus renewing accusations of greenwashing; the manner in which these debates are structured, particularly in social networks. These studies, together with literature reviews on social opposition to transitions, will provide inputs for the eight case studies of transition technologies that constitute the second task. Each study will last for nine months and will be realized by two post-doctoral fellows able to implement interdisciplinary approaches. These analyses, which will complement those already carried out, will allow a comparison of the debates around energy transitions to be drawn up in a third task, a table that will enable the Chair's scientific (analysis of the rules of civic epistemology that are being developed) and operational (recommendations to the Company for the deployment of its technologies) objectives to be achieved. The final task will be dedicated to communication and dissemination, which involves, in addition to academic communications, communications on publication media at the meeting of the press and academic publication and the creation of a strip cartoon on renewable energy deployment. This chair is based on a long-standing collaboration between the Transitions énergétiques et environnementales laboratory (TREE, CNRS / U. Pau) and TotalÉnergies' R&D unit, a collaboration that will be expanded and amplified by this Chair. TotalÉnergie wants to better understand the rules of the game of renewable energy deployment in order to participate in the public debate and to adapt its proposals to the expectations of the public. For their part, the University of Pau has specialized in energy and environmental transitions, and the UMR TREE is the social science laboratory in charge of analyzing these transitions. The partnership has already made it possible to carry out studies of transition technologies, which will serve as a basis for the studies envisaged in the Chair in three ways: - in terms of governance, by involving not only the university team and the company's R&D team, but also a team from one of the company's operational entities in the deployment phase of a technology and a team from the company's strategic services (stakeholder engagement department); in terms of approach, to repeat (and adapt) a methodology for analyzing technologies that has already been tried and tested and consists of a combination of methods from different disciplinary fields; and, finally, in terms of accumulated knowledge, to contribute case studies that will serve to compose the common base. The partnership's objective is, on the one hand, to produce knowledge about the debates surrounding the transitions that are taking place, and in particular the rules of civic epistemology that are being discussed; on the other hand, to provide guidance to the company in the deployment of its technologies, so that it can usefully participate in these debates.
