Iran War's Energy Crisis Claim Hinges on Incomparable Data
The IEA's Fatih Birol has called the 2026 Iran war the greatest energy security crisis in history. The numbers behind that claim are stark. These figures are striking but they are not directly comparable. Here is why. 🧵 https://t.co/oplTLequPN
Current Energy Shock Dwarfs 1970s Crises
I don’t think we have understood yet how serious this crisis is. IEA’s Fatih Birol: ~5 mb/d lost in each of the 1970s oil shocks; ~75 bcm gas after Russia’s 2022 invasion. Now: ~11 mb/d oil and ~140 bcm gas disrupted. https://t.co/6G8leH3lHR https://t.co/ESkY9LyQjx
Spain's Power Prices Rarely Linked to Gas, Unlike UK/Italy
