In this video, Gilles Vaïtilingom (Research Director - CIRAD) discusses the value of biomass with energy needs related to transport. He first traces an history of the use of vegetable oils and then analyzes the substitution potential of conventional fuels by first- and second-generation of biofuels.

In this video, Jean-Philippe Delgenès of INRA offers a very complete overview of the diversity of deposits and channels that enable the biological production of energy vectors.

In this video, Jean-François Filipot (France Energies Marines) presents the energy resources associated with the marine environment, the ways to characterize them, their availability, and the major types of devices that allow them to be exploited.

In this video, Jean Schmittbuhl, Research Director - CNRS / University of Strasbourg, presents the geothermal classification according to the temperatures exploited. For each of these categories, he explains the uses, interests, risks, and maturity levels of the associated operating technologies.

In this video, François Collombat (Project Manager, Hydraulic Production Division – EdF) presents the various components of an hydraulic system, from the dam to the factory outlet. For each of them, he presents the diversity of the devices currently deployed.

In this video, François Collombat (Project Manager, Hydraulic Production Division – EdF) discusses the contribution of hydroelectricity to the energy mix. In particular, he highlights the value of this type of energy for the management of peak and ultra-peak effects.
