How to govern deep geothermal projects? Political, environmental, and scientific issues involved in the debates related to the Strasbourg earthquakes (2019-2021)

International audience ; In 2019-2021 several earthquakes linked to a drilling site located north of the Strasbourg Eurometropolis (Alsace, France) led to significant changes in the policies and discourses of the stakeholders, elected officials, industrialists, prefecture, residents' associations. In December 2020, the prefecture enacted an ordinance to halt all operations on the incriminated site and a moratorium on all such projects near Strasbourg. Our paper analyzes these changes, using the media and the consultation mechanisms as our research field. First, we analyze the changes that have taken place in the institutional space and identify the associated communication issues. Second, we analyze how these reconfigurations are reflected in the narratives of the mainstream local media. Third, we analyze the reaction of the public through an analysis of the comments that appeared in social media (Facebook and Twitter) in reaction to posts by the main actors of the debate on geothermal energy. In conclusion, we propose some reflections on the way the public uptake social media in comparison with traditional media.
