HELSINKI, Finland — Iran's influence over the strategically vital Strait of Hormuz has inadvertently transformed the energy security debate, effectively casting fossil fuels rather than renewables as the primary source of vulnerability.
For decades, the conventional narrative has been one in which renewables were criticized for their intermittency issues and dependence on weather conditions, whereas technologies such as coal, oil, and gas were seen as providing security.
The Middle East conflict and protracted closure of the Strait of Hormuz, a waterway that typically handles around 20% of the world's global oil and liquefied natural gas supplies, have reframed this debate, however, laying bare the risks associated with fragile fossil fuel supply chains.
Energy experts and the CEOs of Nordic energy giants Fortum and Statkraft made this point clear on the sidelines of the Eurelectric Power Summit in the Finnish capital this week.
"I mean, the big mantras, and I'm surprised we haven't heard people talking about this yet, is that fossil fuels are now intermittent and uncertain, which, of course, was the argument levelled against renewables," Kingsmill Bond, energy strategist at U.K.-based think tank Ember, told CNBC in Helsinki.
"Renewables, thanks to batteries, have become actually pretty constant given the sun rises every morning. So, look I think we have moved to a new environment and … we are still far too exposed to the old system – and we need to change, particularly in Europe, we need to change really quickly."
Bond said the current energy shock marks the first time in history where policymakers have a superior alternative technology to turn to for security, comparing the situation today to the 1973 and 1979 oil crises.
"If you go back to the 1970s, what did we do? We built nuclear, but that took 10 years and it was expensive. This time round, we've got solar and wind, batteries and electrification and lots of flexible technologies, which are huge and cheap and we can scale them. And that's what's happening," Bond said.
The U.S. and Israeli-led war against Iran has rattled global energy markets and triggered widespread inflation fears, with Asia's reliance on imported energy sitting at the forefront of the global fossil fuel crisis.
Supply disruptions have also hit hard in Europe and Africa, where countries are responding to rising fuel costs and a considerable threat to food security. With no imminent reopening of the Strait of Hormuz in sight, the situation has prompted many to reflect on the extent to which the world remains deeply reliant on fossil fuel trade routes.
Asked about intermittency concerns regarding imported fossil fuels, Fortum CEO Markus Rauramo said, "It's a different kind of intermittency but absolutely. So, exactly, this is our message that the solution to being dependent on imported CO2-content fuels is to actually have homegrown clean electricity."
He added, "That's the way forward, but then we are very realistic. We are not naïve about the fact that yes, there's intermittency and if you have a business or your home is dependent on gas then it is a big shift."
The evolving energy security debate comes just a few months after fossil fuel leaders had welcomed a paradigm shift in the narrative regarding the energy transition.
Speaking to CNBC at the UAE's annual oil summit late last year, several fossil fuel industry players championed the concept of "energy addition" to secure supply and accommodate new demands from sectors like AI.
Energy addition refers to a push to develop new technologies, such as renewables like solar and wind, in parallel with existing fossil fuels. Energy transition, by contrast, typically refers to the transfer from one energy source to another.
Birgitte Ringstad Vartdal, the chief executive of Statkraft, Europe's largest producer of renewable energy, agreed that the energy security narrative regarding clean technologies has been transformed by the conflicts in Ukraine and Iran.
"And I think also another thing that has been developing over this period is the batteries, right? So, they are much cheaper and they have longer duration for how long they can store," Vartdal said.
Batteries are seen as a way to mitigate the intermittency of renewable energy projects by soaking up surplus electricity when generation is high and discharging it when production dips.
"For some countries, you can see that while in the past you had these shoulder hours in the morning and the evening, they can now much more be taken over by batteries. So, batteries plus solar or batteries plus solar and wind can provide a much more total generation as well."
Shoulder hours refer to the blocks in the day that sit between peak energy demand and off-peak times.
The challenge of intermittency in Norway, which holds a reputation as the gold standard for renewable hydropower, has not been an issue in the same way it has for others in Europe, Vartdal said, before adding that "variability is key" in the security debate.
"In the end, we believe that you need some gas in the system to take the long periods of low production," Vartdal said.
While the Iran war may have moved the needle in the conventional energy security narrative, pivots to alternative energy sources during times of conflict can pose challenges. Some have raised the alarm about Europe's rush to U.S. LNG following Russia's full-scale invasion of Ukraine in early 2022.
"Moving forward, we're going to have a lot more LNG in Europe, and a lot of that LNG will now come from the U.S., given the Strait of Hormuz situation," Jan Rosenow, professor of energy and climate policy at the U.K.'s University of Oxford, told CNBC.
"And that means we are then exposed to one country that is currently seen as rather unstable politically when it comes to international relations, so a very problematic situation indeed. And domestically generated electricity from renewables doesn't face that problem."
Four leading AI models discuss this article
"The transition from fossil fuel reliance to domestic renewables is essentially a transition from fuel-price volatility to infrastructure-capital intensity, favoring companies that build the grid rather than those that extract the commodity."
The article correctly identifies a shift in the energy security narrative, but it conflates 'geopolitical risk' with 'intermittency.' While renewables offer independence, the capital expenditure required to scale grid-scale storage and transmission infrastructure is massive. We are looking at a multi-year capex cycle that will benefit copper, battery-grade lithium, and power grid infrastructure firms like Eaton (ETN) or Schneider Electric. However, the article glosses over the 'energy density' problem; industrial processes—steel, cement, and chemical manufacturing—cannot currently run on intermittent solar and wind. Replacing the Strait of Hormuz's 20% global supply share requires more than just domestic generation; it requires a fundamental redesign of industrial demand, which remains a massive, unpriced risk.
The transition to 'homegrown' energy ignores that the raw materials for batteries and solar panels are largely controlled by China, potentially swapping dependence on the Strait of Hormuz for a more complex, supply-chain-dependent reliance on Beijing.
"The security argument for renewables is stronger rhetorically than operationally until 2027-2028 buildout rates are proven."
The Hormuz closure narrative reframes fossil fuels as the intermittent source, boosting the case for Nordic renewables via Fortum and Statkraft. Yet the piece glosses over deployment velocity: even with cheaper batteries, Europe would need multi-year permitting and grid upgrades to offset 20% of global oil/LNG flows. The shift to U.S. LNG merely swaps one geopolitical chokepoint for another, while winter shoulder-hour variability still requires gas peakers. Policymakers may accelerate subsidies, but mineral bottlenecks and transmission delays cap near-term impact.
Battery storage and solar/wind scaling could still lag behind demand spikes, leaving Europe exposed to price spikes longer than the article implies and delaying any genuine security gain.
"The Hormuz crisis reframes energy security as a *timing* problem, not a technology problem—Europe needs dispatchable power for 7-10 years while renewables scale, and that gap is where real vulnerability lives."
The article conflates two distinct problems: geopolitical supply disruption (Hormuz closure) with renewable intermittency, then declares renewables 'solved' because batteries exist. But this elides a critical gap: Europe's pivot to U.S. LNG doesn't actually reduce energy security risk—it relocates it. Meanwhile, the article assumes battery + solar/wind can replace dispatchable baseload at scale without discussing grid infrastructure costs, permitting timelines, or the fact that Europe still needs 'some gas in the system' (per Statkraft's own CEO). The real story isn't renewables vs. fossils; it's that Europe faces a 5-10 year transition crunch where both are needed, and geopolitical fragility now applies to *all* energy sources, not just oil.
If U.S. LNG replaces Middle Eastern oil and batteries + renewables genuinely displace gas within a decade, Europe's energy security actually improves materially—the article's critics may be overstating transition friction.
"Near-term energy security still requires a robust mix of baseload power, flexible storage, and grid investments; renewables alone cannot eliminate vulnerability in the next decade."
Today’s Hormuz shock underscores supply-chain fragility, but the article’s 'fossil vulnerability' framing risks overstating renewables’ readiness. Storage and transmission upgrades are not universally deployed; seasonal baseload gaps persist, minerals for batteries face bottlenecks, and policy risk can throttle deployment. Europe’s LNG pivot to the US concentrates geopolitical risk on a single supplier, and price spikes can still arise. The piece glosses how quickly grid-scale solution stacks—batteries, demand response, hydro, nuclear—can be scaled. In sum, security remains a multi-vector challenge that keeps fossil and non-fossil pathways tightly interwoven for years to come.
Counter: even with Hormuz, diversified LNG flows and ongoing investments could reduce near-term volatility. The urgency to accelerate renewables, storage, and grid reform is real but the outcome is not yet decisive.
"Energy security in Europe is impossible without prioritizing nuclear baseload to bridge the gap between intermittent renewables and volatile LNG imports."
Claude is right that we are relocating, not eliminating, risk. However, everyone is ignoring the 'nuclear' elephant in the room. If Europe is serious about energy security, the 5-10 year transition crunch Claude mentions is only solvable by extending existing nuclear baseload and accelerating SMR deployment. Relying on intermittent renewables plus volatile LNG imports is a structural disaster. We are ignoring the capital-intensive reality that grid stability requires high-density, non-intermittent sources that aren't tied to geopolitical chokepoints.
"Nuclear faces the same multi-year hurdles as renewables, so it cannot compress the transition timeline Gemini claims."
Gemini overlooks that nuclear restarts and SMRs face identical permitting, supply-chain, and capex delays already flagged for batteries and transmission. Uranium enrichment capacity remains concentrated and years from meaningful expansion, while waste and public opposition add unpriced political risk. This does not solve the 5-10 year crunch but merely relocates it to a different set of bottlenecks Europe has historically struggled to clear faster than renewables.
"Europe's energy security improves only if it commits capex to nuclear AND renewables AND storage simultaneously; hedging across all three is slower and more expensive than the article implies."
Grok's uranium enrichment bottleneck is real, but it's a *different* constraint than renewables' intermittency problem. Nuclear doesn't solve grid variability—it solves baseload. The actual crunch isn't choosing between nuclear and renewables; it's that Europe needs both, plus storage, plus transmission, and all three face permitting delays. Nobody's flagged that the *real* security gain comes from diversification across all three, not betting the transition on any single pathway. That's the unpriced risk: policy will likely pursue all three half-heartedly instead of one ruthlessly.
"Nuclear alone won't solve the 5–10 year crunch; financing, permitting, and waste issues push any ramp well beyond a decade."
Gemini’s 'nuclear elephant' is a well-timed reminder, but it treats SMRs as a fast fix rather than a financing/permitting treadmill. The real constraint isn’t just capex; it’s cross-border siting, public acceptance, uranium supply, waste management, and sovereign guarantees, all of which push any nuclear ramp well beyond a 5–10 year horizon. If European security hinges on a nuclear wildcard, the window for near-term risk reduction remains narrow and brittle.
