Iran War Strengthens the Case for Renewables and Storage
By Leonard Hyman & William Tilles - Jul 06, 2026, 2:00 PM CDT
Defense and reconstruction firms emerge as the biggest winners, while oil and gas producers face longer-term headwinds as post-war supply recovers and consumers accelerate the shift toward alternative energy.
LNG may benefit in the short term from disrupted Gulf supplies, but buyers are expected to diversify away from geopolitically risky exporters, increasing competition from renewables, nuclear and domestic energy sources.
The war could ultimately accelerate investment in renewables, energy storage and efficiency, as governments and consumers seek more secure, less volatile energy systems, reducing long-term reliance on fossil fuels.
Let’s say that the Iran war has ended. Being investors, not political pundits or military strategists, we won’t opine on who won. Major events, however, have investment consequences. The incontrovertible winners, on a short and long-term basis, are the engineering, infrastructure, and construction firms that repair the damage, and the munitions manufacturers that replace the equipment consumed in the war. Nobody else comes close.
What about oil? Oil prices have already retreated. Iran may rejoin the world oil market, adding to supply. (If Putin ends the Ukraine war, that will add even more supply.) The war’s price and delivery disruptions, though, could dampen consumption over the long term just as the Oil Embargo of the 1970s did, except that consumers today have alternatives, whereas those in the 1970s just had to use less. Today they can switch to renewables or seek supplies from new or newly revived fields outside the Persian Gulf (Guyana and Venezuela). More supply and less demand: not a good business proposition.
US consumers remained supplied but suffered a price shock because oil sells at world prices, and US oil companies didn’t offer $70 oil to fellow Americans if they could sell it to foreigners at $110. That’s the competitive market, price the product to keep up with the competition, right? Eventually, consumers will ask: “Do we really need this aggravation? Maybe electricity isn’t that bad. Even Ferrari makes an electric car.” This war might help new non-Gulf suppliers pick up market share at the expense of legacy firms, but that means more supply fighting for the same demand. Some oil companies do better, but the industry does worse. Related: Dip in U.S. LNG Imports to EU Spells Trouble for Trade Deal
Filling the gap caused by war damage in the Persian Gulf (and Russian shortfalls) looks like a short-term winning strategy for LNG suppliers. Will Europeans find enough LNG to fill storage for winter? Can Asian markets find substitutes for Persian Gulf LNG? Looking beyond the short term, however, the war may signal to LNG consumers the need to diversify supply, to buy from somewhere safe. Depending on Russia proved not too bright, and the Persian Gulf could flare up any time.
Buy more from the USA? That would make sense under normal circumstances, but requires a rethink in light of US politics. “LNG exports reduce domestic supply, put upward pressure on US natural gas prices, thereby raising electricity and home heating bills. And guess which political leader pushes for exports?” How about that as a sound bite in the next two elections? The Trump administration has contradictory energy policies, a willingness to tear up treaties, and thinks foreigners are ripping us off. LNG contracts with US suppliers, thus, will have political risks attached. Canada, maybe?
In sum, LNG buyers will try to diversify supply, but, in the end, may consider how much LNG they can replace with something less risky and more domestic. LNG, then, has to compete with renewables and nuclear power. It faces the same risks, then, as oil: geopolitical instability that affects price and supply. Those risks always existed, but now consumers can find competitively priced alternatives.
What about nuclear power, the conservative politician’s favorite non-carbon energy resource? No doubt the war will encourage more talk about this expensive source of energy, and more government schemes to subsidize it. We can see money made refurbishing the existing nuclear fleet to lengthen its life and efficiency, and to source nuclear fuels domestically but not in trying to resurrect a decades-old fission technology by subsidizing an existing design or by building smaller versions of the same thing. Maybe fusion will change the picture, but we don’t see the virtue of opting for the most expensive and contentious means of producing electricity. (Think of the comment made by an AI user who compared Chinese vs US AI by saying that the Chinese version produced 90% of the output of the US version at 10% of the price. Nuclear power produces electricity, and a windmill or solar plus battery combo produces the same power at half the price.)
In the end, technology and economics should trump politics. The war, we believe, will nudge more energy policy makers toward three economically competitive resources not subject to international price and supply instability: energy efficiency, renewables, and storage. Efficiency (which we used to call conservation) may be the cheapest energy resource, but politicians will avoid it like the plague. (Comment heard during the recent heat emergency, despite warnings of grid collapse: “What business have they telling me how to set my air conditioner. I’ll do what I want.”) Ongoing R&D will reduce renewable and storage costs further. But there is a catch. Chinese manufacturers dominate the market. European and American policymakers might not want to buy from them, but the rest of the world will.
In short, the Iran war has not produced dramatic business or investment opportunities except for the obvious winners we mentioned first. It did not drive a stake into the heart of the evil fossil fuel industry, a scene many (but not OilPrice readers) would have gleefully anticipated, especially if directed by Werner Herzog. No, we think that the oil and gas industry was a loser in the sense that ending the war might raise supply,
