The unprecedented blockage of the Strait of Hormuz has created an energy shortfall far exceeding past crises. This severe shock is set to accelerate the global transition to clean energy and reshape future dependencies.

In the hushed, yet charged atmosphere of the International Energy Agency’s Paris headquarters on March 19, a grim prognosis was being delivered.

Fatih Birol, the IEA’s Executive Director, sat with Michael Liebreich, outlining a scenario that transcended mere market volatility to paint a picture of profound global dislocation.

What began as a regional maritime incident had, in a matter of weeks, escalated into what Birol unhesitatingly termed “the mother of all energy crises,” a shockwave far exceeding the seismic shifts of 1973 and 1979.

Before the Strait of Hormuz, that vital choke point for a third of the world’s seaborne oil, became impassable, roughly 20 million barrels of crude transited its waters daily.

By the time Birol spoke, that figure had plummeted to a mere four million barrels.

The resulting 16-million-barrel daily shortfall wasn’t just a disruption; it was an existential threat to the global energy system, a void three to four times larger than the supply reductions witnessed during the infamous Arab oil embargo or the Iranian Revolution.

Those 1970s crises, each removing a fraction of today’s deficit—approximately five million and three to four million barrels per day respectively—had already triggered global recessions and fundamentally reshaped energy policy for decades.

Birol’s comparison was stark, implying that 2025 and 2026 would emerge, in hindsight, as an equally, if not more, defining inflection point.

The immediate international response, spearheaded by the IEA, had been unprecedented.

A week prior to Birol’s conversation, member countries had unanimously agreed to release 400 million barrels from strategic reserves, the largest coordinated drawdown in history.

This extraordinary measure, while temporarily driving oil prices down by $18 per barrel upon announcement, was, in Birol’s candid assessment, a palliative, not a cure.

The tools available to international energy institutions—strategic reserves, diplomatic coordination, and demand-side emergency measures—were demonstrably inadequate to address the root cause: a physical transit constraint enforced by military means.

This structural inadequacy, Birol implied, was a stark data point in itself, laying bare the vulnerabilities of the existing global energy security architecture when confronted with a deliberate closure of its most critical maritime artery.

The crisis extends far beyond crude oil.

Approximately 20 percent of global liquefied natural gas (LNG) also navigates Hormuz, alongside other critical commodities like fertilisers and sulphur.

While LNG constitutes a smaller fraction of overall natural gas supply (around three percent globally), its disruption has immediate and severe consequences.

The pain, Birol noted, is disproportionately borne by Asian economies – India, China, Japan, and Korea – which are direct importers of Gulf LNG.

Europe’s exposure, though indirect, is no less significant, as heightened competition for dwindling global spot LNG cargoes inevitably drives up prices, impacting electricity costs through gas’s marginal role in wholesale power generation.

What began as a regional oil hiccup quickly metastasized, in Birol’s framework, into one of the most profound structural economic dislocations the global economy has encountered, with emerging and developing nations poised to suffer the gravest impacts.

The IEA’s immediate, three-pronged response involved the aforementioned reserve release, near-daily high-level diplomatic calls to coordinate market stability, and a demand reduction programme promoting measures like expanded teleworking and free public transportation.

Yet, the limitations of each were clear.

Reserves offer temporary price relief but cannot replace lost physical supply.

Diplomacy can sustain confidence but cannot conjure oil that isn’t moving.

Marginal demand reduction, while useful, cannot close a 16-million-barrel daily chasm.

The IEA’s role, Birol conceded, was one of damage limitation, not resolution.

The true solution, he insisted, remained unequivocally political: the reopening of the strait.

Everything else was merely managing consequences.

This crisis, however, is not merely a test of immediate response mechanisms; it is, in Birol’s most analytically substantive argument, a potent catalyst for structural transformation.

He drew parallels to the 1970s, which spurred three enduring changes: a massive push into nuclear power (accounting for 40 percent of today’s operational capacity), a fundamental improvement in automotive fuel efficiency (reducing per-kilometre fuel consumption by 50 percent over two decades), and geopolitical diversification of energy sources (such as Europe’s initial turn to Russian gas to lessen Middle Eastern reliance).

Each was a rational response to an identified risk, creating structural shifts that persisted for decades.

Birol posits that the current crisis will similarly catalyse structural responses, but with a crucial difference: it will accelerate the deployment of technologies already on a growth trajectory, those that simultaneously address climate change and energy security.

Solar, wind, batteries, nuclear, and electric vehicles all reduce dependence on imported fossil fuels, irrespective of whether the primary motivation is decarbonisation or supply security.

The crisis does not invent new technologies; it supercharges the existing transition by adding a powerful energy security premium to their economic and environmental merits.

A pivotal data point underpins Birol’s structural thesis: 75 percent of all new power plants installed globally last year were solar.

This figure, gleaned from IEA tracking data, isn’t just an energy transition milestone; it signifies a profoundly altered energy landscape compared to the 1970s, when new capacity was almost exclusively fossil-fuelled or nuclear.

Higher gas prices, a direct consequence of LNG market competition, will now further incentivise the shift to renewables, a dynamic already demonstrated in Europe following Russia’s invasion of Ukraine.

There, renewable installations surged not solely due to climate policy, but because domestic generation from solar and wind became economically compelling on energy security grounds.

The Hormuz crisis, therefore, adds a third, potent layer to the renewable deployment case, joining cost competitiveness and decarbonisation mandates.

This confluence of drivers, Birol believes, guarantees a stronger, more durable boost to clean energy than any previous crisis.

Beyond solar and wind, Birol anticipates an acceleration across several specific vectors.

Nuclear power, for instance, will see renewed momentum through lifetime extensions and refurbishment of existing plants, the advancement of new conventional projects, and potentially the elusive commercialisation of small modular reactors (SMRs).

Electric vehicles, in Birol’s framework, are the modern-day equivalent of the 1970s’ automotive efficiency improvements, promising a lasting reduction in oil demand rather than temporary behavioural conservation.

If high prices and insecurity drive accelerated EV adoption, the structural impact on oil demand will be profound and permanent.

Notably, Birol expresses scepticism regarding the call for accelerated investment in new oil and gas exploration.

His reasoning is pragmatic and quantitative: new field development typically requires seven to ten years from licence award to production.

This timeline is fundamentally incompatible with addressing a supply gap measured in months and years.

While diversification is a sound general principle, the technologies capable of responding within a relevant policy horizon are those already “on the growth curve”: solar, wind, storage, nuclear refurbishment, and electrification of transport.

The candid discussion also shed light on the IEA’s evolving institutional mandate.

Amidst public calls from figures like US Energy Secretary Chris Wright for the IEA to refocus on its traditional “hard energy security” role, away from climate scenarios, Birol’s response was carefully diplomatic but substantively clear.

The very nature of the current crisis, demonstrating how deeply interconnected energy security and climate solutions are, implicitly validates the IEA’s broader, more holistic analytical approach.

The mother of all energy crises, while unleashing immediate devastation, may paradoxically serve as the ultimate accelerant for a global energy transition, fundamentally reshaping not just markets but geopolitical dependencies for decades to come.
