Current energy projections often envision an expansion of nuclear capacities to decarbonize future energy systems. However, this contrasts with the historic and current status of the nuclear industry, marked by techno-economic challenges for both light-water and non-light-water reactor technologies. Regardless, projections of strong nuclear growth have persisted since the 1970s. This paper investigates the “nuclear energy paradox” which shows the recurring divergence between historical projections and actual developments. A data compilation of long-term energy projections from international organizations such as the IAEA and the IEA as well as energy system models like GCAM and MESSAGE, as used in the IPCC, reveal a recurring pattern of high-growth projections for nuclear power. Such projections often rest on techno-economic assumptions such as substantial cost reductions. We propose the concept of nuclear imaginaries to show that these assumptions are embedded into techno-economic visions of nuclear power de

États-Unis Iran Israël guerre What is currently happening in Brussels under the guise of regulatory simplification is being presented as something technical and logical. Less regulatory pressure, more competitiveness. A series of so-called omnibus bills are intended to streamline legislation. Reporting obligations are being limited and reassessments of raw materials postponed. It sounds like administrative efficiency. In Washington, things are moving even faster: Trump is dismantling the basis for climate laws while the world continues to warm up. The framing is the same: rules slow down businesses, and a slowed-down business community makes us poor. But that reasoning assumes something that is not true: that everyone wants the same thing from the market.

Il y a peu, la Commission de réglementation nucléaire (NRC) aux États-Unis a donné son accord pour la poursuite du projet Natrium de la société TerraPower. Cette société recevant le soutien de Bill Gates va pouvoir débuter la construction de la première unité de sa centrale à Kemmerer, dans l’état du Wyoming. Pour certains scientifiques, cette approbation arrive trop rapidement.

Much of today's sustainability discourse emphasizes efficiency, clean technologies, and smart systems, but largely underestimates fundamental physical constraints relating to energy-matter interactions. These constraints stem from the fact that Earth is a materially closed yet energetically open system, driven by the sustained but low power-density flux of solar radiation. This Perspective reframes sustainability within these axiomatic limits, integrating relevant timescales and orders of magnitude. We argue that fossil-fueled industrial metabolism is inherently incompatible with long-term viability, while post-fossil systems are surface-, materials-, and power-intensive. Long-term sustainability must therefore be defined not only by how much energy or material is used, but also by how it is used: favoring organic, carbon-based chemistry with limited reliance on purified metals, operating at low power density, and maintaining low throughput rates. Achieving this requires radical technological shifts toward l

The growth in US power demand is surging to its highest rate in decades, driven first by the electrification of oil and gas production and then by the build out of data centers. While still below the 5-10% growth seen in China, the world’s first “electrostate," the US power sector is experiencing rapid structural growth. The country is delivering more than a 3.5% annual power demand growth rate for the first time in several decades, potentially positioning the US as the world’s next “electrostate,” despite the strong oil and gas focus of the Trump administration.

A new study suggests that the Gulf Stream was stronger during the last ice age due to more powerful winds, indicating that future changes in wind patterns could weaken the Gulf Stream, affecting European climate and North American sea levels. This research enhances our understanding of the Atlantic Meridional Overturning Circulation (AMOC) and its vulnerability to climate change.

Troquant son costume de financier en banque pour sa plume de Bon Pote, Thomas Wagner est une des figures emblématiques de la défense de l’environnement sur internet; il le dit lui même il "prendra sa retraite quand le réchauffement climatique sera de l’histoire ancienne » Sur les réseaux sociaux ou son blog, celui que l’on surnomme « l’influenceur du climat » livre un travail complet, sourcé et dense sur les sujets liés à l’actualité climatique : mieux comprendre le rapport du GIEC, comment faire son bilan carbone ou encore en apprendre plus sur l'histoire des voitures électriques, tout y passe. Par où commencer quand on veut s’informer sur la situation environnementale? Comment limiter son impact carbone au quotidien? Comment lutter contre l’eco-anxiété?

Evidence shows a continuing increase in the frequency and severity of global heatwaves1,2, raising concerns about the future impacts of climate change and the associated socioeconomic costs3,4. Here we develop a disaster footprint analytical framework by integrating climate, epidemiological and hybrid input–output and computable general equilibrium global trade models to estimate the midcentury socioeconomic impacts of heat stress. We consider health costs related to heat exposure, the value of heat-induced labour productivity loss and indirect losses due to economic disruptions cascading through supply chains. Here we show that the global annual incremental gross domestic product loss increases exponentially from 0.03 ± 0.01 (SSP 245)–0.05 ± 0.03 (SSP 585) percentage points during 2030–2040 to 0.05 ± 0.01–0.15 ± 0.04 percentage points during 2050–2060. By 2060, the expected global economic losses reach a total of 0.6–4.6% with losses attributed to health loss (37–45%), labour productivity loss (18–37%) and i

Voilà comment certains présentent Jean-Marc Jancovici, Polytechnicien et ingénieur de formation, expert du sujet climatique depuis plus de vingt ans. Qui eut cru que c’est d’un homme de soixante ans, suivi par près d’1 million de personnes sur LinkedIn, qui cumule plus de 20 millions de vues sur YouTube, que viendrait cet engouement pour l’écologie ? Son discours franc, sans langue de bois, sa critique du système politique et des élites ont grandement contribué à en faire un personnage apprécié et très médiatisé. Mais qui se cache réellement derrière Jean-Marc Jancovici ? Dans cet épisode, on aborde bien évidemment les sujets qui lui tiennent à coeur, mais on va aussi au-delà, afin d’en savoir plus sur l’homme qui se cache derrière la cause. J’espère que cet épisode vous plaira, et je remercie Jean-Marc pour sa transparence et sa sincérité. Bonne écoute !

Named one of the “world’s ten most influential intellectuals” by MIT, Douglas Rushkoff is an author and documentarian who studies human autonomy in a digital age. Rushkoff’s work explores how different technological environments change our relationship to narrative, money, power, and one another. He coined such concepts as “viral media,” “screenagers,” and “social currency,” and has been a leading voice for applying digital media toward social and economic justice. In the conversation we talk about the power of ideas, our disconnection from reality, going meta, ancestral fears, tech billionaires mindset and how they are preparing for the apocalypse. We also reflect on the urgent need to be more human and reconnect with what is essential.

“Combustion is the problem – when you’re continuing to burn something, that’s not solving the problem,” says Prof Mark Jacobson. The Stanford University academic has a compelling pitch: the world can rapidly get 100% of its energy from renewable sources with, as the title of his new book says, “no miracles needed”. Wind, water and solar can provide plentiful and cheap power, he argues, ending the carbon emissions driving the climate crisis, slashing deadly air pollution and ensuring energy security. Carbon capture and storage, biofuels, new nuclear and other technologies are expensive wastes of time, he argues.

A coal-fired power plant that had been mothballed has become the first of its kind to be put back on to the network in Germany, as debate rages over how Europe’s largest economy will cope without Russian gas. The facility in Lower Saxony, which is owned by the Czech energy company EGH, has received emergency permission to run until April in an attempt to boost energy production.
