For more than a century, oil has been treated as the bloodstream of the modern economy. It moves cars, trucks, ships and aircraft. It feeds petrochemical plants, powers armies and shapes foreign policy. But before oil reaches the consumer, it must pass through an elaborate chain of wells, pipelines, refineries, storage tanks, ports, tankers and narrow maritime passages.
Every link in that chain can be attacked.
That vulnerability is no longer theoretical. Ukraine has used comparatively inexpensive long-range drones to strike Russian refineries, pipelines, storage depots and export facilities. Reuters reported that attacks in the first five months of 2026 shut primary refining units with a combined capacity of about 2.85 million barrels a day. Later strikes contributed to fuel shortages and forced Russia to reroute supplies towards politically important regions. The lesson is stark: a drone costing a fraction of a refinery can interrupt an asset worth billions.
The Middle East has delivered an even larger warning. The conflict that began in February 2026 severely impeded flows through the Strait of Hormuz, producing what the International Energy Agency called the largest supply disruption in the history of the global oil market. The strait normally carries roughly one-fifth of the world’s petroleum liquids and one-fifth of global liquefied natural gas trade. When such a narrow waterway becomes contested, the consequences travel rapidly into petrol pumps, airline fares, food prices and inflation worldwide.
Then there is the Red Sea. Houthi threats around the Bab el-Mandeb Strait have shown that even routes designed to bypass one chokepoint may run into another. A tanker can avoid danger only by travelling farther, paying more for fuel and insurance, and adding days to delivery. Energy security is not simply about possessing oil underground. It is about whether that oil can be processed, transported and delivered safely.
So, are these vulnerabilities accelerating the search for more resilient, efficient and affordable alternatives?
Yes—but with an important qualification. They are accelerating diversification, not producing the immediate disappearance of oil.
History offers a guide. The oil shocks of the 1970s did not end petroleum dependence. But they changed national behaviour. Governments created strategic reserves, imposed fuel-efficiency standards, diversified suppliers and expanded nuclear power. A crisis did not produce one solution; it produced several layers of protection.
The same pattern appeared after Russia’s invasion of Ukraine in 2022 and the collapse of Europe’s assumption that Russian pipeline gas would remain dependable. Europe rushed to secure liquefied natural gas, reduce consumption, diversify imports and accelerate renewable energy under REPowerEU. It used emergency fossil alternatives to survive the present while expanding cleaner domestic sources for the future.
That distinction matters. In the short term, an oil shock often encourages more drilling, larger reserves and new pipelines. Governments facing angry consumers cannot announce that solar panels will solve next month’s diesel shortage. They release stockpiles, subsidise fuel and seek alternative suppliers.
But in the longer term, every shock strengthens the case for systems that do not depend on fuel continually arriving from a distant and unstable region.
A solar farm requires minerals, equipment and investment when it is built. Once operating, however, it does not need daily shipments of sunlight through a naval chokepoint. A wind turbine does not require tankers to cross hostile waters. Rooftop solar, local batteries, micro-grids and distributed generation reduce dependence on imported fuels and on a few large facilities.
They are not invulnerable, but their risk is dispersed. Destroying one refinery can affect an entire region. Disabling thousands of small generators is far more difficult.
Affordability is also changing the equation. IRENA reports that renewables remained the most competitive source of new electricity generation in 2025, with average costs of about 44 dollars per megawatt-hour for solar photovoltaic power and 33 dollars for onshore wind. Battery costs, according to the IEA, fell by more than 90 per cent between 2010 and 2025. The IEA also estimated that global clean-energy investment reached about 2.2 trillion dollars in 2025—roughly twice the investment flowing into fossil fuels.
Energy security is therefore joining climate change and falling technology costs as a great engine of the transition.
Electrification is especially important because oil’s largest market is transport. Electric cars, buses, two-wheelers and railways convert transport from an oil problem into an electricity problem. Electricity can be generated from many domestic sources: solar, wind, hydro, nuclear, gas, coal or some combination.
The more transport is electrified, the less a country’s mobility depends on a tanker passing through Hormuz.
For India, this is not an abstract debate. India imports most of the crude oil it consumes, so distant conflicts arrive here as pressure on the rupee, the current account, government finances and household budgets. Expanding electric public transport, improving vehicle efficiency, strengthening rail freight, promoting rooftop solar and building domestic storage are not merely climate policies. They are strategic insurance.
Nuclear power is also returning to the security conversation. Unlike wind and solar, nuclear plants can provide steady power for long periods, although they require high upfront investment, skilled regulation and lengthy construction.
In 2025, the United States adopted executive actions seeking to expand nuclear capacity from about 100 gigawatts to 400 gigawatts by 2050 and encourage advanced reactors, including modular designs. Whether those targets are achieved is uncertain, but the direction is revealing: nuclear energy is increasingly being framed as infrastructure for national resilience.
Still, we should resist triumphalism.
Renewable systems have vulnerabilities of their own. Solar and wind are variable. Grids need expansion. Storage must scale. Projects face permitting delays and high financing costs.
Critical-mineral processing is also highly concentrated. The IEA found that the top three refining countries controlled an average of 86 per cent of key energy minerals in 2024. Replacing dependence on Middle Eastern oil with excessive dependence on one country’s batteries, solar modules or refined minerals would not eliminate geopolitical risk. It would change its geography.
The answer, therefore, is not merely to replace oil wells with lithium mines. It is to diversify mineral suppliers, expand recycling, develop alternative battery chemistries and build domestic manufacturing capacity wherever economically possible.
Nor is oil about to vanish.
Aviation, shipping, heavy trucking, defence and petrochemicals remain difficult to electrify fully. Long-distance aircraft and ships require fuels with very high energy density, while petrochemicals use oil not merely as a source of energy but as a raw material. ([IEA][9])
Even the forecasts differ. The IEA’s Oil 2025 report projected demand reaching a plateau near 105.5 million barrels a day around 2030. But its later current-policies scenario showed oil use continuing to rise towards 2050 if governments do not strengthen existing policies.
The future is not predetermined. Technology, politics, prices and consumer behaviour will determine the speed.
So what is the real conclusion?
War is not creating the energy transition. Solar costs, battery innovation, electric vehicles, climate concerns and industrial competition were already pushing the world in that direction.
But attacks on refineries and blockades of sea lanes are giving the transition a harder, more urgent logic.
A country may debate climate targets. It may postpone carbon taxes. It may disagree over the ideal pace of electrification. But no government enjoys watching its economy become hostage to a missile, a drone or a narrow strait thousands of kilometres away.
The future energy system will probably not be purely renewable, purely nuclear or immediately free of fossil fuels. It will be more diverse, more electrified, more efficient and more distributed. It will combine renewables with nuclear power, storage, flexible grids, strategic reserves, energy efficiency and, for many years, some continuing use of fossil fuels.
There will also be an important shift in how governments think about cost.
The price of oil is not merely the amount quoted on an international exchange. Its real cost includes naval protection, strategic reserves, vulnerable shipping lanes, war-risk insurance, imported inflation, currency pressure and the economic consequences of sudden disruption.
Once those hidden costs are included, domestic renewable electricity, electrified transport and energy efficiency become more attractive—even when their initial investment appears expensive.
Oil will remain important for years. In several sectors, it may remain indispensable for decades. But every burning refinery, damaged pipeline and threatened tanker route sends the same message: dependence has a price beyond the price printed on a barrel.
The energy transition will not occur because the world suddenly loses its appetite for oil. It will advance because countries gradually lose their tolerance for the economic and strategic vulnerability that comes with depending upon it.
And the world is beginning to calculate that vulnerability far more seriously.
