Energy Security: renewables to surge amid the Iran conflict

How businesses and investors can adapt to the latest energy shocks

The escalating Iran war is changing the narrative around investment in renewables. They are no longer confined to niche climate reports; they are reshaping global energy markets and redefining where capital flows across power, mobility and industry. For countries dependent on Middle‑Eastern oil and gas, the risk of supply shocks is turning renewables, batteries, hydrogen and electric vehicles (EVs) into tools of energy security, not just instruments of climate policy.

Renewables as a shield against volatility

The conflict has exposed the vulnerability of long‑distance fossil‑fuel routes through chokepoints like the Strait of Hormuz, making domestic renewables an attractive hedge against price spikes and supply interruptions. Wind and solar, once seen mainly as emission‑reduction tools, are now treated as strategic assets that reduce reliance on imported oil and gas. Geopolitical risk is directly accelerating the pace and scale of clean‑energy deployment.

As more countries tighten climate‑and‑security‑linked targets, renewables plus flexible support technologies (short- to long-duration batteries, advanced inverters, etc) are becoming central to the mix, reinforcing the idea that renewables are now a structural shift in capital allocation, no matter what happens next in the Middle-East.

Batteries and storage in a shock‑prone world

To turn intermittent renewables into a reliable backbone, grids need flexible storage. In that context, technologies such as lithium‑ion batteries, vanadium redox flow batteries (VRFBs) and other grid‑scale storage solutions play very different roles in balancing short‑term swings versus multi‑hour or multi‑day needs. For a deeper look at how these storage options compare in terms of cost, performance and emissions, see A comparison of clean energy storage solutions.

As the Iran war and the renewed focus on investment in renewables push governments and investors to prioritise resilience, storage becomes a key enabler that turns volatile renewable generation into a more predictable and secure energy system.

Hydrogen as a strategic buffer

Beyond batteries, green hydrogen is emerging as a potential long-duration energy buffer for industrial gas demand. In future, hydrogen-ready turbines and industrial plants could switch partially or fully to domestically produced hydrogen during supply disruptions, reducing exposure to imported natural gas. Although large-scale deployment remains limited today, hydrogen is also seen as a key decarbonisation pathway for sectors where direct electrification is difficult, such as heavy industry and certain transport applications.

For a deeper look at how hydrogen technologies can support cleaner transport, see The promise of hydrogen technologies in transportation.

This hydrogen-centred shift reflects the broader Iran-war-induced surge in renewables investment: as geopolitical risk increases, investors are showing greater willingness to support projects that deliver both decarbonisation and energy-security benefits.

EVs and mobility under geopolitical stress

In 2025, the global EV fleet avoided oil consumption roughly equivalent of roughly 1.7 million barrels per day – around 70% of Iran’s annual oil exportst hrough the Strait of Hormuz, according to London‑based Ember. Parallel estimates from European‑based organisations such as Transport & Environment suggest that in the EU alone, several million electric cars are already shaving tens of millions of barrels off annual oil demand, reinforcing the idea that EVs are no longer just a climate tool but a growing pillar of energy security.

How businesses and investors can prepare for escalation

If the war escalates further, energy‑price volatility, supply‑chain disruptions and regulatory responses are likely to intensify. Businesses and investors can take several concrete steps to reduce their exposure:

  • Diversify energy sources and contracts – firms that rely heavily on imported oil and gas can reduce risk by locking in multi‑year contracts, blending renewables into their supply mix or investing in on‑site solar and storage where feasible.
  • Accelerate electrification and efficiency – shifting to electric heat, vehicles, and machinery under long‑term power‑purchase agreements with renewables can lock in more predictable costs while reducing overall exposure to price swings.
  • Stress‑test supply chains and counterparties – mapping how far‑upstream suppliers and logistics routes depend on Middle‑Eastern energy or key shipping lanes helps identify bottlenecks and build contingency plans.
  • Tilt towards resilience‑centred assets – from a portfolio perspective, investors can tilt exposure towards renewables and storage infrastructure, EV‑linked value chains and green hydrogen projects – all of which align tightly with the Iran war, renewables investment theme.
  • Monitor and adapt to policy shifts – governments are likely to respond with faster permitting for renewables, stricter fuel‑efficiency rules and new incentives for EVs and domestic production of critical technologies.

By treating war‑related risks not as temporary shocks but as signals of a more volatile, security‑conscious energy landscape, businesses and investors can position themselves on the resilient side of the transition: tied to renewables, storage, hydrogen and electrified mobility, rather than to fragile, import‑dependent fossil‑fuel systems.

Final thoughts

The escalating Iran war and renewed focus on investment in renewables are not just driving a short-term spike in energy prices; they are signalling that the global system is entering a more volatile, security-conscious era. In this context, renewables, batteries, hydrogen, and EVs are no longer niche “green” bets, but core building blocks of a more resilient and diversified energy and mobility infrastructure.

For businesses and investors, the key insight is simple: building resilience today pays off whether the conflict escalates or not. Locking in cleaner, more flexible energy sources, shortening dependence on vulnerable supply routes and aligning with policy‑driven electrification trends can reduce both financial and operational risk over the medium term. By treating energy‑security and climate‑transitions as two sides of the same coin, companies and capital markets can position themselves not just to survive a more turbulent world, but to lead it.
