End : 16 December 2026 à 17:30
On 16 December 2026, the I.JET.IDF Chair (Investment Dynamics in Renewable Electricity and Energy Justice in Île-de-France) is organising its first science-action day.
By bringing together the scientific research carried out within the chair with feedback and insights from stakeholders in the Île-de-France region, the conference will explore the key dimensions of the Île-de-France electrification process and its challenges, particularly from the perspective of socio-spatial justice and political materialities. The discussions will alternate between presentations by key public and private stakeholders involved in electricity policy-making in Île-de-France, scientific insights into governance and evolving conceptions of electricity, and finally, by the presentation of initial research carried out under the chair, notably through a mini-exhibition of maps. The afternoon will be devoted to practical round-table discussions to learn more about initiatives on the ground, explore certain issues in greater depth, raise questions, and identify information needs to shape future work within I.JET.IDF.
Organised by a scientific chair for public policy, this event is primarily focused on supporting decision-making, for the benefit of decision-makers and local residents. Hosted at the Cité Descartes campus of the UGE (Champs-sur-Marne), it aims to be both a forum for the collective sharing of knowledge and a space for raising questions, drawing on scientific research that brings together different perspectives on the history and understanding of electrification in the Île-de-France region.
The I.JET.IDF Chair is funded by the Île-de-France Region’s Social Sciences and Humanities Chairs Programme, 2025 edition. It is led by Emmanuelle Santoire, a research fellow at the CNRS within UMR 8134 LATTS (Laboratory for Techniques, Territories and Societies), specialising in geography and law.
