Notes acides sur la crise du jus (1) / Sylvestre Huet, {Sciences2}, 15/11/2016Le système électrique français est en crise. Et surtout son cœur nucléaire. La dernière manifestation en est l’annonce par RTE – le gestionnaire du réseau haute tension, chargé non pas d’assurer mais de surveiller l’équilibre entre l’offre et la demande – d’un risque de coupures d’électricité cet hiver. Diantre !... lireLe moment de vérité (1/2) / Matthieu Auzanneau, Oil man, 16/11/2016Tout est prêt pour le dernier acte : sommes-nous sur le point d’atteindre les limites physiques à la croissance ? L’élection de Donald Trump pourrait accélérer le rendu du verdict... lireScaling innovation for climate change / Jonathan Coony, Development in a changing climate, 16/11/2016We were standing at ground zero in the fight against climate change, looking at a still body of water and talking. Our group was gathered along the edges of a “farm pond,” a technique used by farmers to enhance agricultural resilience to climate change, which often impacts countries through crippling droughts. A farmer demonstrated the measures he had taken to protect his livelihood from the extreme weather events that were increasingly common in his region... lireClimate Change and U.S. Leadership Under President Trump / Lindsay Iversen, associate director of climate and resources at the Council on Foreign Relations, Energy, Security and Climate, 15/11/2016In the week since Donald Trump’s election, the energy and environment community has struggled to come to grips with candidate Trump’s positions on climate change and energy policy—positions that were not deeply explored during the campaign or raised by the moderators in any of the debates. If enacted, the policies Trump has proposed will reverberate beyond American borders, with potentially serious ramifications for U.S. leadership in other foreign policy realms... lireRising uncertainties about the climate regime in the aftermath of the US presidential election / Jaime de Melo, Brookings blog, 15/11/2016The Paris Agreement—which entered into force only on November 4—is already in jeopardy amid rumors that the U.S. might pull out. This could lead to a reduction in efforts by China and other nations. The Paris Agreement is really the first important step taken to limit temperature increase, and, as highlighted in the e-book “Towards a Workable and Effective Climate Regime,” by Scott Barrett, Carlo Carraro, and myself last year, it must meet two conditions that look increasingly difficult to attain. Meeting these conditions will be difficult for reasons related to science and to the U.S. election outcome... lireFinancing the Climate-Change Transition / Hans Joachim Schellnhuber, Christian Thimann and Axel Weber, Project Syndicate, 14/11/2016Unless the world reduces greenhouse-gas emissions rapidly, humanity is likely to enter an era of unprecedented climate risks. Devastating extreme-weather events are already increasing in frequency, but much of the worst climate-related damage, such as a sustained rise in sea levels, will be recognized only once it is too late to act... lireElectricity Rate Design for the Real World / Severin Borenstein, Energy Institute at Haas blog, 14/11/2016For decades economists have bemoaned the fact that retail electricity prices don’t adjust to reflect the volatile cost of providing energy.  Because electricity is not storable, the wholesale cost can change by a factor of five or more within a single day, but the price to most end-use customers remains constant.  It’s the equivalent of the price at the gas pump being held fixed while the world oil price ranges between $20 and $140 a barrel…only compressed in time... lire
