IEA Electrification Scenario Could Wipe 18mb/d of Oil Demand by 2035

On 22 September 2026, the International Energy Agency (IEA) released analysis showing that accelerating global electrification could eliminate 18 million barrels per day (mb/d) of oil demand by 2035, nearly double the volume that current policies are on track to avoid. The number arrived on the same day as a senior energy transition dialogue held on the sidelines of the UN General Assembly, timed deliberately to shape the terms of COP31.

The figure is not a theoretical ceiling. The IEA frames it as the product of technologies already available and economics already favourable, which makes the gap between what is achievable and what current policy delivers a policy gap rather than a technology one. For anyone positioned across energy, mining, and infrastructure, that distinction carries real weight.

What follows below maps the specific projections, the investment infrastructure they require, the supply-chain vulnerabilities the IEA itself flags, and where the political architecture is already showing cracks. By the time you finish, you will have the data to judge whether this scenario marks a genuine inflection point or an ambitious target with a credibility problem.

The IEA’s 18 million barrel projection: what the numbers actually say

The scenario is built on three levels, and the distance between them is the whole story. Global electrification, the share of final energy consumption met by electricity rather than direct fossil fuel combustion, sits at roughly 23% today.

Under current policies, the IEA projects that figure reaches only about 30% by 2035. With technologies already on the market and already cost-effective, it could reach approximately 33%. The COP31 target, the so-called “35×35” pledge, pushes to 35% by 2035.

The IEA describes the 35% target as being “within striking distance” of what is already economically rational.

The gap that matters is not the one between what is possible and what is affordable. It is the gap between what is affordable and what policy currently delivers.

Read that way, the 5-percentage-point distance between the current-policy trajectory and the COP31 target is not a technical shortfall. It measures how far political ambition still has to travel. That distinction determines whether energy investors treat this scenario as a planning input or a policy aspiration.

The 18 mb/d oil demand reduction flows from a specific mechanism, not a macro assumption. The IEA states plainly that the cut is mainly the result of rapid electric vehicle uptake replacing petrol and diesel consumption in road transport, the largest single segment of global oil demand. Delivering it would require roughly 1,400 TWh of additional electricity consumption each year, about double the annual growth rate recorded over the prior decade.

Set against the baseline, the ambition becomes concrete. Under current policies, electrification avoids around 10 mb/d of oil demand by 2035. The high-electrification path nearly doubles that. The report was commissioned by Türkiye’s COP31 presidency and Australia, and published on 22 September 2026.

The current-policy baseline for EV oil displacement sits at roughly 10 mb/d by 2035, a figure the IEA now frames as the floor rather than the ceiling of what the transition can deliver.

Understanding this three-tier structure is the prerequisite for reading everything downstream. The headline number alone cannot tell you what is already happening, what is economically rational, and what still depends on political delivery.

Rewiring the grid: the USD 1.2 trillion annual investment requirement

If the demand story is about oil disappearing, the supply story is about capital arriving, and the scale required is where opportunity and obstacle sit in the same frame. Delivering accelerated electrification depends on the power system being able to carry it.

According to IRENA’s roadmap, global grid investment must roughly double to approximately USD 1.2 trillion per year. That is not an optional complement to the scenario. It is the structural condition on which the entire high-electrification path rests.

The payoff on the consumer side is what makes the political case. The IEA projects that fuel-importing nations could save more than USD 400 billion per year on energy costs by 2035 versus 2025 levels, rising above USD 500 billion at current elevated energy prices. The capital case and the political case become visible together: the countries spending on grids are also the ones cutting their import bills.

The IEA identifies three structural prerequisites for delivering the scenario:

• Grid infrastructure investment at scale
• Intelligent and flexible power networks capable of managing higher, more variable loads
• Resolution of concentrated supply chains for critical technologies and minerals

For investors in grid infrastructure and clean energy project finance, the USD 1.2 trillion figure is a durable demand signal. But the deployment timeline carries a political risk that pricing models need to account for, and that risk concentrates in one place.

Several grid technology shifts that underpin the USD 1.2 trillion annual investment requirement remain underpriced in equity markets, including smart grid management systems and flexible demand-response infrastructure that are structural prerequisites for absorbing the additional 1,400 TWh of annual electricity consumption the scenario demands.

Where the financing gap is sharpest

The problem for developing and emerging economies compounds in three directions at once. The grid investment need is heavily concentrated there, affordable finance is least accessible there, and the COP31 agenda does not yet contain binding financing commitments.

Fitsum Assefa Adela, planning and development minister for Ethiopia, which is set to host COP32, flagged the absence of financing commitments in the COP31 agenda as a critical gap, calling for meaningful increases in financial resources, technology transfer, and technical assistance.

IRENA’s longer view underlines what is at stake. Its roadmap holds that electricity’s share of final energy use must rise above 50% by 2050 to stay on a 1.5°C-compatible path, which means the grid build-out beginning now is the first phase of a much longer commitment.

The clean-power problem: why electrification without decarbonisation is a risk, not a solution

Here is the contradiction sitting at the centre of the electrification agenda. The scenario assumes electrification reduces emissions, but the emissions arithmetic only holds if the electricity being generated is itself clean, and the COP31 pledge is silent on that condition.

The IEA acknowledges the awkward part directly: because oil plays a minimal role in generation, electrifying transport reduces oil demand regardless of how the electricity is produced. The 18 mb/d oil story is structurally robust even if coal and gas fill the generation gap. The emissions story is not.

Under the high-electrification path, the IEA projects a 40% reduction in CO₂ emissions from transport, buildings, and industry by 2035. Climate Action Tracker analysis, as reported by Climate Change News, sets out the conditions under which that projection actually holds: coal-fired generation must fall by approximately 70% and gas-fired generation by approximately 60% by 2035 to align with a 1.5°C pathway.

Climate Change News reports that the COP31 electrification pledge “leaves out clean power commitment.”

That is the “dirty electrification” risk in plain terms. Analysts warn that if rising electricity demand is met by coal and gas rather than renewables, the pledge produces more generation without genuine decarbonisation. Climate Change News has separately reported that fossil fuel expansion plans in several COP31 host-nation contexts are flagged as inconsistent with the demand-destruction scale the scenario implies.

The IEA frames electrification as reinforcing, not replacing, existing commitments. It identifies three complementary pillars:

• Doubling the rate of energy efficiency improvement (carried from the COP28 pledges)
• Tripling installed renewable energy capacity (also carried from COP28)
• The high-electrification trajectory itself

For investors, the practical read is that two separate theses are hiding inside one headline. The oil demand trade holds up almost regardless of the generation mix. The climate trade depends entirely on it. Those are not the same position, and whoever conflates them is underwriting the wrong risk.

Critical minerals and supply-chain concentration: the unresolved obstacle at the centre of the scenario

The IEA names critical minerals as a threat to the scenario in its own analysis, which makes this a scenario-level risk acknowledged by the report’s authors rather than an outside critique. Concentrated supply chains for critical technologies and minerals, the IEA states, must be resolved for the high-electrification path to be achievable.

The mechanism is straightforward. Delivering 18 mb/d of oil demand avoidance depends on EV adoption at scale, and EVs at that scale require battery minerals, principally lithium, cobalt, nickel, and manganese, plus copper for grid expansion, at volumes current supply chains are not configured to deliver on the required timeline.

The IEA flags several categories of supply-chain risk:

• Battery minerals for EVs, including lithium, cobalt, and nickel
• Grid-expansion materials, principally copper
• Geographic concentration of processing capacity

That concentration cuts two ways for investors. It is a potential bottleneck that could throttle scenario delivery, and simultaneously a potential demand catalyst for producers operating in those chains, provided policy and capital align to expand output.

What the IEA does and does not tell us

Honesty about the gaps matters here. The IEA has named the obstacle without providing the quantitative detail to fully bound it.

The available high-electrification release does not include specific tonnage figures or percentage demand-growth projections for named minerals. Where minerals appear in accessible material, they sit within broader IRENA and IEA transition analyses rather than in clearly labelled scenario-specific detail. The structural risk is stated; the numbers that would let you size it precisely are not yet on the table.

The transition mineral supply and demand picture for lithium, cobalt, nickel, and copper is where the IEA’s scenario-level risk statement becomes a quantifiable market signal, with forward supply curves for each mineral sitting well below the volumes implied by a 35% electrification rate by 2035.

The broader context reinforces the direction of travel. The IEA World Energy Outlook 2025 notes that electricity demand grows faster than overall energy use in every scenario, with the Net Zero Emissions pathway showing the strongest oil demand implications from fleet electrification.

For mining and resource investors, the significance is that the IEA has embedded critical mineral supply chains directly into the geopolitical and financial architecture of the transition. The scenario’s oil projections are only as credible as the mineral chains beneath them, which is why this is where the analysis intersects most directly with resource portfolio positioning, and where conventional commodity cycle analysis captures the least.

What the scenario changes for investors, and what remains genuinely uncertain

Pull the four threads together and a usable distinction emerges: some of this investment picture is now sharpened, and some of it stays contingent on political outcomes that are not yet resolved. The defining variable is the gap between the cost-effective potential of roughly 33% electrification and the COP31 target of 35%.

The 33% trajectory is already economically rational, which makes it a significant demand signal in its own right. The incremental 2 percentage points to 35% require political delivery and should be treated differently in any investment framework.

Three areas of investment direction are confirmed regardless of whether the top target is met.

The unresolved political variable deserves stating plainly. As of 22 September 2026, the COP31 agenda contains no financing mechanism for developing-economy grid investment, and the clean-power commitment that would validate the emissions projections is absent from the pledge text. Türkiye’s parallel Antalya Pledge on AI, aimed at sustainable AI and clean energy, signals the breadth of the host agenda but does not fill either gap.

Fossil fuel demand erosion has been accelerating across multiple consumption segments beyond road transport, a trend the IEA’s three-tier electrification scenario sits within rather than solely drives.

IRENA’s roadmap holds that electricity’s share of final energy use must exceed 50% by 2050 to remain 1.5°C-compatible, anchoring the 2035 target in a far longer trajectory.

The practical framework is this. You can treat the 33% electrification path as a structural baseline for demand planning across grid, EV, and mineral supply-chain positions. The 35% COP31 target is better read as an optionality layer that adds upside if political delivery materialises, not as a primary underwriting assumption. The combined COP31 action agenda carries an estimated 8.5 to 10 billion metric tonnes of emissions-reduction potential, per COP31 president-designate Murat Kurum, but that potential is a target, not a commitment.
