摘要:Within a period of two years, the issue of energy transition has become a topical theme in France, in civil society and in academic circles. Although consensus appears to have been reached on the need to change our energy system based on the consumption of non-renewable energies with negative impacts on the environment, taking action appears more difficult, as shown by the recent demonstrations in Brittany which brought together entrepreneurs, employees and local elected representatives against the levy of an ecotax on the transport of goods by road. After recalling the stakes of energy transition (1.1), we shall attempt to show that it is perhaps the approach taken – an approach taken from the top and essentially technical – which explains in part, the difficulties of making energy transition effective, leading to the assumption of a “false start” (1.2).
