A sudden surge in crude oil prices, triggered by Israeli air strikes on Iranian infrastructure, has exposed fissures in Britain’s energy security planning. Brent crude rose above $85 a barrel on Monday, a 6% jump, as markets priced in the risk of a broader Middle Eastern conflict disrupting supply routes through the Strait of Hormuz. For a nation still weaning itself off fossil fuels, this volatility is a stark reminder that the transition is not yet complete.
The strikes, which targeted oil refineries and storage facilities in southwestern Iran, represent the first direct military action on Iranian soil since the Iran-Iraq war. While Israel claims the operation aimed to disable Tehran’s nuclear weapons programme, the immediate economic shockwave has rippled across global markets. The UK, which imports roughly 8% of its crude oil from the Middle East, faces an immediate 2p rise in petrol prices at the pump, according to the RAC.
But the deeper issue is strategic. Britain’s energy security strategy, published in 2022, emphasises renewables, nuclear power, and domestic gas production as buffers against foreign supply shocks. Yet progress has been glacial. Offshore wind capacity has grown, but planning delays mean several major farms are years behind schedule. The government’s target of 50GW of offshore wind by 2030 now looks aspirational. Nuclear power, meanwhile, remains mired in cost overruns and design disputes. Hinkley Point C, the only new plant under construction, will not come online until 2029 at the earliest.
This leaves the UK vulnerable to precisely the kind of price spike we are seeing today. When geopolitical tensions flare, the country’s reliance on spot markets for liquefied natural gas (LNG) becomes a liability. Unlike pipeline gas, which is tied to long-term contracts, LNG prices swing wildly. In 2022, after Russia’s invasion of Ukraine, the UK spent £50 billion on energy subsidies to cushion households. That bill would be higher today, with inflation already squeezing budgets.
The Labour government, which inherited this strategy, now faces a test. Rachel Reeves, the Chancellor, has warned that “economic stability” is her watchword, but she has limited tools. A windfall tax on oil and gas producers could raise revenue, but it risks discouraging investment in the North Sea, where output is already declining. The clean power superpower ambitions espoused by Ed Miliband, the Energy Secretary, require billions in private capital, which is harder to attract when interest rates are high.
There is a silver lining, however. High oil prices make renewables more economically attractive by narrowing the cost gap with fossil fuels. The levelised cost of offshore wind has fallen by 72% since 2012, and onshore wind and solar are now cheaper than gas in many markets. If the government can accelerate grid connections and reform planning laws, the current crisis could catalyse a faster buildout. That is the calm urgency of the situation: each price shock is a reminder that dependence on imported fossil fuels is a strategic vulnerability.
The physical reality is simple. The Earth’s lithosphere holds a finite amount of hydrocarbons, but the climate system’s tolerance for their combustion is even more limited. Every barrel burned adds 430 kg of CO₂ to the atmosphere. The extra 1 million barrels a day that OPEC would normally supply to calm markets cannot materialise if Iran’s facilities are offline. Meanwhile, the UK’s Strategic Petroleum Reserve, which holds about 4 million barrels, offers only a 10-day supply at current consumption rates.
This week’s oil spike is not just about geopolitics. It is a stress test for the energy transition. If Britain cannot insulate its economy from a regional conflict in the Middle East, it has not yet built the resilience it needs. The data are clear: renewables and electrification are the path to energy independence. The question is whether the political system can move fast enough to match the pace of a warming, fracturing world.
