This episode addresses the question of energy decarbonisation and the energy mix in France, but also the possible solutions for storing it to meet continuous energy demands. None of this will be possible without talking to citizens and supporting them during the energy transition. These are the subjects addressed by energy geopolitician Marie-Claire Aoun and doctor and explorer Jean-Louis Étienne, in the podcast Ça change tout with journalists Thierry Guerrier and Yolaine de la Bigne.
