La bonne équation pour réduire massivement les émissions de CO₂ / Patrick Criqui, The Conversation, 5/04/2016

Le 16 mars dernier, l’Agence internationale de l’énergie a dévoilé ses premières estimations pour les émissions de CO2 énergétique en 2015 : pour la deuxième année consécutive les émissions mondiales ont été stabilisées, alors même que la croissance économique avait été de plus de 3 % par an, en 2014 et en 2015… lire

Transition énergétique : le mythe du modèle allemand à l’épreuve du modèle britannique / Jacques Percebois, Observatoire Energies d’Entreprises, 7/04/2016

Comment prend corps la croissance verte autour de l’Hexagone ? Approche « pragmatique » des Britanniques ou vision « idéologique » des Allemands, Jacques Percebois examine les sources d’inspiration pour faciliter une transition énergétique réaliste en France… lire

Des flux et des stocks / Claude Crampes et Thomas Oliver Léautier, TSE Debate, 7/04/2016

A cause de la non-stockabilité de son produit, l’industrie électrique n’a pu se développer que par des investissements gigantesques en capacités fiables de production et de transport. Les politiques environnementales actuelles qui donnent la priorité aux ressources renouvelables intermittentes inversent l’ordre causal : ce n’est plus la non-stockabilité qui détermine les technologies, ce sont les technologies qui imposent la stockabilité… lire

Oil prices and the global economy: It’s complicated / Maurice Obstfeld, Rabah Arezki, Gian Maria Milesi-Ferretti, Vox, 8/04/2016

Oil prices have fallen sharply and remained persistently low, but the expected demand boost has not materialised. This column notes that when nominal interest rates are pinned at zero, lower inflation due to a drop in oil prices raises real interest rates, working against the traditional positive income effects. Dangers arise from the possibility of unanchored inflation expectations and dislocations – including corporate and sovereign defaults – that could spook already jittery financial markets. To combat such negative loops, demand support by the global community – along with a range of country-specific structural and financial-sector reforms – is urgent… lire

Britain is Sending a Huge Nuclear Waste Consignment to America – Why? / Gordon MacKerron, SPRU, the Energy Collective, 6/04/2016

A very unusual exchange is about to take place over the Atlantic. The UK is sending some 700kg of highly enriched uranium to be disposed of in the US, the largest amount that has ever been moved out of the country. In return, the US is sending other kinds of enriched uranium to Europe to help diagnose people with cancer… lire

Why Solar Will Need to Cost 25¢ Per Watt by 2050, And How the Industry Might Get There / Varun Sivaram and Shayle Kann, Energy, Security and Climate, 7/04/2016

For solar power to become truly mainstream, how much should it cost? And is the industry on track to meet that target? We tackle each of those questions in an article released today in the journal Nature Energy. In a nutshell, our answers are: for solar power to supply nearly a third of the world’s electricity by 2050, it will ultimately need to cost around 25 cents per watt (in today’s dollars), fully installed. And that target may be out of reach without a major technological shift… lire

The EU Carbon Trading Market: A Decade of Experience / Timothy Taylor, Conversable Economist, 7/04/2016

It’s common to hear proposals that the US should adopt a “cap-and-trade” system for reducing climate emissions. Indeed, back in 2009 the House of Representatives passed the American Clean Energy and Security Act, the so-called “Waxman-Markey” act, which would have implemented such a law, but the legislation died in the US Senate without ever being brought to a vote. In the meantime, the European Union has now had a cap-and-trade policy in place for 10 years. How well is it working?… lire

Electrification: A Key Driver for a Decarbonized and Energy Secure Europe / Hans ten Berge, Eurelectric, the Energy Collective, 6/04/2016

As European policymakers explore pathways to decarbonise the EU economy, the heating, cooling and transport sectors are moving very much into focus. Contributing as much as 66% of Europe’s greenhouse gas emissions, these sectors have become a key challenge in unlocking Europe’s sustainability potential. However, decarbonising Europe in a cost-efficient manner remains a crucial challenge for industry, policymakers and customers in today’s energy world in view of the decentralised nature of heating and transport, as well as their high dependency on fossil fuels… lire
