Video Description

Débat avec Jean-Marc Jancovici et Yves Marignac organisé par le magazine Kaizen en février 2023. Pour rester sous une augmentation de 1.5 degrés, nous devons laisser entre 60 et 80 % des réserves des énergies fossiles dans le sol. Quelles énergies faut-il privilégier pour remplacer le pétrole, le gaz, le charbon ? Des énergies renouvelables ou le nucléaire ? Liste des points abordés : 00:02:54 Quel regard portez vous sur l'état de notre Terre ? 00:07:05 Est-ce que vous pensez qu'il y a un risque d'effondrement possible ? 00:12:00 Le projet de sobriété du gouvernement vous paraît-il suffisant, pérenne, ou pas assez structurel ? 00:23:25 Peut-on imaginer une société sans dérivés de pétrole ou sans pétrole du tout ? 00:29:08 La croissance verte est-elle un mythe ? 00:33:54 Est-il possible de découpler les émissions de gaz à effet de serre et la croissance ? 00:39:42 Afin de décarboner la société, sur quels postes pourrait-on agir en termes de sobriété ? 00:44:10 Quel est le poste qui requiert le plus de sobriété ? 00:49:14 Est-ce qu'il est envisageable de tenir un scénario énergie 100% renouvelable ? 01:01:38 Dans un contexte géopolitiques instable (exemple de l'Ukraine), comment va t-on gérer la stabilité des centrales nucléaires ? Et sur la sécurité de l'approvisionnement (30% de l'approvisionnement venant du Niger), comment gérer d'un point de vue géopolitique l'approvisionnement des centrales ? 01:11:03 Précisions de JM Jancovici et débat sur la sureté, les dangers du nucléaire, la gestions des déchets. 01:21:50 Précisions de Y Marignac et débat sur la gestions des déchets, et sur la trajectoire 100% renouvelable. 01:25:04 Comment choisir la trajectoire à adopter ? 01:29:55 Comment convaincre les politiques de mettre en place un changement de système ? 01:33:50 Pensez vous que le système chinois serait plus performant pour une transition énergétique ? 01:41:02 Est-ce qu'il y a quelque chose dans le discours de l'autre qui vous a séduit et inversement ?
