The next fuel war
Published 2 October 2026
The strongest importer is not always the one that finds a cheaper barrel. Sometimes it is the one that needs fewer barrels.
The IEA's Global EV Outlook 2026 estimates electric vehicles displaced around 1.7 million barrels a day of oil use in 2025, with China accounting for about one million. Under its Current Policies and Stated Policies scenarios, worldwide displacement reaches around five million barrels a day by 2030, while China's reaches about 2.7 million. These are scenario results, not measured future consumption. The newer edition updates the earlier 2025 outlook rather than turning its assumptions into a guarantee. IEA Global EV Outlook 2026; Scenario detail.
Displacement means demand avoided relative to a counterfactual in which the same travel used oil. It is not necessarily the same as a five-million-barrel reduction from today's observed total consumption. Travel can grow while oil intensity falls. Petrochemicals, aviation and other uses can grow while road demand becomes less oil-dependent. The denominator matters as much here as it did at Hormuz.
Electrification moves the exposure. A vehicle needs electricity and charging infrastructure rather than petrol; the grid needs generation, transmission and balancing. If electricity comes partly from imported fuels, the transport system may still have an international energy link. If generation is domestic and diversified, the nature of the vulnerability changes more substantially.
Coal remains part of that reality. The IEA's Coal 2025 demand assessment projects global consumption at about 8.845 billion tonnes in 2025 and identifies China and India as dominant sources of use. The publication is a 2025 assessment, not a live September 2026 count. Its role in this story is to prevent a false claim that growing renewable generation has already removed conventional fuel from the energy system. IEA coal-demand assessment.
Oil security and climate strategy are related but not identical. An efficient electric vehicle can lower oil dependence. Its climate outcome depends on electricity generation and the broader lifecycle. A coal supply expansion may improve immediate power availability while creating a different emissions and environmental burden. Policy has to manage more than one objective.
India's ethanol programme replaces part of the petrol blend with domestically sourced fuel. The petroleum ministry's August 2025 response reports cumulative foreign-exchange savings of Rs 144,087 crore from the programme from ESY2014-15 through July 2025, and about 24.5 million tonnes of crude substitution. These are ministry-reported programme estimates, not savings audited by this publication. Ministry response.
The same response gives average ethanol procurement cost at Rs 71.32 per litre as of 31 July 2025, including transport and GST, and says that weighted ethanol cost was then above refined petrol cost. That destroys a simplistic claim that blending must always make the pump cheaper. The policy can pursue import reduction, rural income and environmental goals without every litre having a lower input cost. Source record.
Nor should litres substituted be confused with identical useful energy delivered. Fuel properties and vehicle calibration matter. The ministry acknowledges that older vehicles may need earlier replacement of some rubber parts and gaskets, while arguing that broad concerns over performance were overstated. A consumer should use the manufacturer's compatibility and service guidance rather than a universal claim that every vehicle experiences the same result.
There is a fiscal transition too. The IEA's EV scenario projects more than $65 billion of net global fuel-tax shortfall by 2030 if governments do not change taxation as oil use is displaced. It discusses possible changes through vehicle, road-use or electricity taxation. The toll can move even when the fuel changes. EV tax discussion.
The longer-term geopolitical implication is bargaining power. A country that can substitute, use less or generate more energy domestically can negotiate with a supplier from a stronger position. It does not need to eliminate every import. It needs credible alternatives at the margin and a system resilient enough to use them.
The pre-war slowdown was not the wartime shortage
The IEA's Global Energy Review 2026 estimates oil demand rose by 650,000 barrels a day in 2025, about 0.7%, below the 2010-19 average annual increase of 1.4 million barrels. It attributes the slowdown partly to weaker petrochemical feedstock growth, electrification and biofuel use. The assessment is about 2025, before the 2026 war shock changed the near-term market. IEA 2026 review of 2025.
The same report describes naphtha, LPG and ethane as important feedstocks for plastics. A fuel story that considers only road travel misses this demand. When cars consume less oil, chemicals can still need hydrocarbon material. The uses differ in how easily they can substitute and how strongly they depend on industrial growth.
A structural slowdown in demand growth does not guarantee cheap oil during a physical disruption. Growth can be slower than in the past while current demand still exceeds deliverable supply. The September 2026 shortage and the preceding year's slowdown therefore belong in the same account, not opposite ideological accounts.
Long-run projections should be handled with that humility. The IEA's 2024 India outlook expected substantial demand growth to 2030 and significant savings from efficiency and EV adoption. Its numbers are a pre-war outlook, not an updated September 2026 baseline. The purpose of keeping it in the story is to show the planned direction and its assumptions, not to pretend the next several years are already measured. Source record.
Energy strategy has to work across both horizons. It needs supplies for this week's refinery and investment for the next decade's system. A government that only chases the next cargo can remain vulnerable. A government that speaks only of the future can leave today's essential activity exposed. The art is connecting the two budgets and the two clocks.
The battery changes the supplier map
The 2026 EV outlook records more than twenty million electric-car sales in 2025, about one-quarter of new car sales. China accounted for nearly seventy-five percent of electric-car production and more than eighty percent of battery-cell production. These are industry estimates for 2025, not a claim that the same percentages apply to India's entire vehicle stock or battery requirements. IEA's manufacturing and sales assessment.
That creates another trade-off. Replacing petrol with electricity can reduce recurring oil imports, while the vehicle and battery supply chain can depend on imported equipment, materials or technology. Those are not identical vulnerabilities: a battery is not purchased anew every time the vehicle travels, while petrol is. But neither supply chain should be declared geopolitically free.
The report says electric two- and three-wheeler sales grew by more than thirty percent in India in the first quarter of 2026. This is a reported quarterly growth rate, not the share of all Indian vehicles already electrified. The relevant transition for many users can arrive on two or three wheels before it arrives through a new private car. Source record.
The same report estimates EV electricity demand could exceed 1,500 terawatt-hours by 2035 without policy changes, around four percent of projected global electricity demand. That global share does not tell a city whether its local feeder can handle an evening charging peak. Generation adequacy and local delivery capacity are different constraints, just as global oil supply and the next accessible tanker were different constraints. Source record.
Smart charging can move some demand away from peak hours; vehicle-to-grid can potentially provide flexibility. The IEA notes that standards and regulation remain uneven and that few models support the latter. A promising mechanism is not yet a universal operational asset. The energy transition should be read through deployed equipment and actual access, not only technology announcements.
The strategic prize is fewer unavoidable barrels at the margin. In a supply crisis, the fuel not required does not need a ship, insurance or an emergency dollar payment. It still needs the alternative system to function. Reducing one dependency succeeds only when the replacement has been built well enough to carry the work.
The mineral route still passes through the fuel route
The IEA's Global Critical Minerals Outlook 2026 estimates that the leading refining country's average share, excluding rare earths, rose to seventy-two percent in 2025 from seventy percent in 2023. It identifies Indonesia as the leading nickel refiner and China as dominant in other key energy minerals. This is a measure of refining concentration across the report's mineral set, not a claim that one country owns seventy-two percent of every mineral deposit. IEA critical-minerals outlook.
The distinction between mine and refinery matters just as reservoir and oil refinery mattered earlier. The deposit's country, the processing country's technology and the finished component's manufacturer can be different. Diversifying mines without diversifying processing may leave the most important bottleneck intact. A battery supply chain needs its own map of rights, capacity, routes and permissions.
The 2026 report also connects Hormuz to mineral processing. It says the Middle East supplies around one-quarter of global sulphur and that half of global seaborne sulphur trade passes through the strait. Sulphuric acid is used in fertiliser and in processing minerals including copper, lithium, cobalt and nickel. It reports disruption prompting China to curb sulphuric-acid exports in May 2026. These are the report's dated assessments, not independently verified current flows. Source record.
A transition away from oil can therefore remain exposed to a shipping crisis associated with oil. The ship may carry sulphur instead of crude, but the material can enter a battery or crop-input supply chain. The connection is physical, not rhetorical. The new energy system still consumes industrial inputs that need processing, finance and transport.
Stockpiles can buy time here too, though the IEA warns that mineral markets differ from oil. Material quality, processing steps, substitution and storage economics vary. One should not copy a ninety-day oil rule onto every mineral without asking what the factory actually needs. A reserve of the wrong chemical form may be as unhelpful as crude held where no refinery can receive it.
The objective is better-distributed resilience, rather than an impossible claim of no dependence. A country can reduce daily fuel imports and still work to diversify battery inputs. It can use more domestic electricity while improving grid equipment supply. Each change needs to be measured against the vulnerability it is intended to reduce, not judged by whether it abolishes every foreign relationship.
That is why this is an energy story converging on fuel rather than a defence of one molecule. Oil remains important, gas brings separate constraints, coal supports much of the present grid, and alternatives change the next decade's demand. The market trades today's bottleneck while investment decides tomorrow's choices.
