Thread: Each week I run a simulation of Australia’s main electricity grid using rescaled generation data to show that it can get very close to 100% renewable electricity with 24GW/120GWh of storage (5 hrs at av demand) Results: Last week: 100% RE Last 269 weeks: 98.5% RE (1/5)

My favourite chart from the @IEA special report on electrification. Electricity is only 23% of Final Energy (No big deal), but it's 37% of Useful Energy (What?) and delivers 46% of GDP (Wow!) And it's going clean, fast. Still think there's no transition? iea.blob.core.windows.net/as…

Everyone thinks AI will accelerate science. I think it will mostly accelerate disappointment. Not because AI isn’t powerful, but because we’ve made this exact mistake before in the 1990's. Let me tell you about it. 🧵1/

Over the past year, lots of people have asked me what I think of the argument Jean-Baptiste Fressoz makes in More and More and More - that sources of energy are only ever additive. TLDR: not much. mliebreich.substack.com/p/mo…

"Cour des Comptes estimates that EDF – already drowning in debt – will have to spend €460bn (£394bn) by 2040 to upgrade the nuclear park (le Grand Carénage), to bring the grid into the 21st century, and new reactors won’t be ready until the middle of the century. All of this is creeping into French electricity bills. France is now facing what Britain has already been dealing with for years: the upfront investment cost of a modern energy system. I struggle to enthuse over the £40bn Sizewell C nuclear project." Telegraph 4th Aug 2026 telegraph.co.uk/business/202…

Le McKinsey Global Institute vient de publier le prix du même mégawattheure nucléaire par pays. Ça fait un peu mal : 63 dollars en Chine, 65 en Corée, 190 en France. Le triple. Les trois quarts de l’écart tiennent à nos coûts de construction. Et ces coûts explosent chez nous principalement par incompétence collective. Nous produisons du sur-mesure à l’unité, nous lançons les travaux avant que le design soit finalisé, nous changeons tout le temps de plans, et nous nous appliquons des normes plus strictes que n’importe qui sur terre pour faire plaisir aux lobbies. Même le devis des 6 prochains EPR2 est passé de 50 à 70 milliards avant même d’avoir coulé le premier béton. C’est d’autant plus rageant que dans les années 70-80, nous avons construit notre flotte dans les règles de l’art : des designs simples, à la chaîne. 4 réacteurs par an. Boum. C’est ce que font la Corée et la Chine aujourd’hui. Rien de sorcier, rien qui ne soit réplicable. Pire, c’est nous qui avons inventé la méthode ! Et l’enjeu de l’énergie n’a jamais été aussi urgent. Dans le même rapport, McKinsey note que 55 % du prix d’un data center repose sur le prix de l’électron. La révolution IA qui définit la nouvelle hiérarchie des nations passe par notre capacité à remettre à plat notre stratégie nucléaire. Concrètement il s’agit de : •Figer un design simplifié de l’EPR2, aligné sur les normes coréennes, et ne plus jamais y toucher. •Annoncer la construction des EPR 7 à 14 pour que la filière se mette en ordre de marche. •Pressuriser Bruxelles pour que le financement puisse se faire à taux réduit. Il n’y a pas de futur industriel et donc de futur prospère pour la France si nous ne faisons pas ça au plus vite. Nous aurions déjà dû le faire il y a 10 ans.

Pakistan's solar boom coincided with a 21% rise in electricity in 2 years. All of the 21% rise in electricity demand was met with distributed solar - actually grid electricity fell 3% in the last 2 years...
