Video chapters: 00:00:00 INTRODUCTION - Why criticize Jean-Marc Jancovici's speech? 00:07:35 - ARGUMENT 1 - Solar and wind... a lot of noise for almost nothing 00:07:40 - 1 Solar and wind, that's the thickness of the line 00:08:53 - 2 Solar and wind production is exploding, with incredible growth rates 00:11:49 - 3 Solar and wind, soon to be major energies? 00:14:04 - 4 The collapse of solar and wind prices 00:15:30 - ARGUMENT 2 - Solar and wind: intermittency, a fatal problem 00:15:37 - 1 Controllable VS Intermittent 00:16:47 - 2 Intermittency for dummies, explained in a caricatured and misleading way 00:18:55 - 3 The real problem of intermittency according to Jancovici 00:27:35 - ARGUMENT 3 - Solar and wind consume too many metals 00:29:01 - 1 Enough metals for a low-carbon global electricity system 00:30:55 2 - 2 Stock is good, but is flow doomed? 00:34:47 - ARGUMENT 4 - Solar and wind, diffuse energies, consume too much space 00:36:07 - 1 A wind turbine per km2? 00:38:52 - 2 Solar, the enemy of forests and agricultural land? 00:42:26 - 3 Nuclear takes up less space 00:43:59 - ARGUMENT 5 - Solar and wind: energy inefficiency, EROI too low 00:44:04 - 1 The energy return rate against renewables - FEAT Le Réveilleur 00:50:38 - 2 Qualities and defects of fossil fuels: what Janco is hiding from us 00:55:18 - ARGUMENT 6 - Solar and wind only exist thanks to fossils 00:55:23 - 1 The interweaving of energies, Janco style 00:58:53 - 2 Solar panels without fossil fuels: mission impossible? 01:02:02 - 2a Mining and transport 01:02:44 - 2b Transport 01:03:31 - 2c Road transport 01:05:33 - 2d Fossil-free boats: sailing ships from the Middle Ages? 01:08:46 - 2e Fossil-free metals: mission impossible? 01:11:05 - 3 What happens if we can't do without 100% fossil fuels? 01:16:03 CONCLUSION: Renewables AND nuclear: another vision of the transition
