[en] A set of 11 documents addresses various aspects and issues related to energy transition and to climate by 2050, according to four main scenarios (frugal generation, territorial collaborations, green technologies, restorative bet) and for different specific sectors. For each sector, the conclusion of previous works is recalled in terms of induced impacts of scenarios. Therefore, the different documents address and discuss: technical and economic conditions of the electricity mix for each scenario and according to different meteorological scenarios, an analysis of needs in materials (notably materials for high potential technologies associated with electric vehicles, electric renewable energies, and nuclear), impacts of scenarios on lands (associated with agriculture, forests, renewable energies, buildings and transports), the adaptation to climate change (levers and brakes of notably climate-sensitive sectors: transports, agriculture, forest, industry and building), the perception of the different scenarios by a panel of citizens (in terms of individual and collective expectations), macro-economic et sector-based impacts of scenarios, opportunities of the gas and liquid fuel sectors, for the proteins sector, for the new construction sector, for the last-kilometre logistics sector (growth possibilities, technical and organisational transformations and adaptations), and issues related to territories in order to make communities aware of the benefit of prospective approaches
