The global energy transition is losing momentum just as the world needs it most. Geopolitical friction, sluggish clean-technology deployment in key sectors, and persistent fossil-fuel subsidies have slowed the shift away from oil, leaving economies exposed to the same supply shocks that sent energy spending surging during the 2022 crisis. Yet a set of proven tools, from electric vehicles to efficiency mandates to fuel-switching rules in aviation and shipping, already shows measurable results. The question is whether governments and industries can scale those tools fast enough to offset the drag.
Electric Vehicles Are Already Displacing Oil at Scale
The single largest dent in oil demand right now comes from electrifying passenger cars and light trucks. Oil displacement from EV adoption exceeded 1.3 million barrels per day in 2024, a figure that has grown sharply year over year as battery costs fall and charging networks expand. That volume is roughly equivalent to the entire daily oil consumption of a mid-sized European economy, and it arrives without any single dramatic policy intervention; it is the cumulative effect of purchase incentives, tightening emissions standards, and consumer preference shifts across dozens of markets.
In the United States, the EPA finalized multi-pollutant standards for Model Year 2027 and later light-duty and medium-duty vehicles, a rule that constrains the technology mix automakers can sell and pushes fleets toward higher efficiency and electrification. The EU has gone further: Regulation (EU) 2023/851 introduces a 100% emissions reduction target for new cars and vans from 2035, effectively banning internal-combustion-only sales in one of the world’s largest auto markets. Still, political reality is catching up with ambition. The Council of the European Union gave final approval in late May 2025 to additional compliance flexibility for carmakers struggling to meet near-term CO2 targets, a concession that illustrates how transition timelines can soften even when long-term goals remain intact.
Even with this policy softening, the direction of travel is clear. Automakers have locked in multi-year investment cycles for batteries, software, and dedicated EV platforms, while consumers increasingly expect charging access in homes, workplaces, and public spaces. The result is a structural shift in oil demand: each new electric car displaces gasoline or diesel consumption over its lifetime, and as EVs move from niche to mass-market, the aggregate effect becomes visible in refinery balances and fuel-tax receipts.
Efficiency Gains Fill the Gap Where EVs Cannot Reach
Electrification alone will not solve the problem. Heavy industry, long-haul freight, and petrochemical feedstocks remain deeply tied to refined oil, particularly in manufacturing-heavy economies. China’s manufacturing sector consumes a great deal of oil, and its transportation system is heavily dependent on refined products as well. In those segments, energy efficiency is the fastest available lever.
The IEA’s Energy Efficiency 2023 report frames a target of doubling efficiency progress globally, a goal that would reduce demand in buildings, industry, and transport even where direct electrification is years away. Practical steps already exist. The IEA’s 10-Point Plan to Cut Oil Use, published in March 2022, recommended that countries reduce highway speed limits by at least 10 km/h, backed by a country-level analysis showing measurable fuel savings. Such measures are politically unglamorous but operationally immediate, requiring no new infrastructure and no technology breakthroughs.
Beyond transport, building codes, appliance standards, and industrial process optimizations can lock in lower energy use for decades. Retrofitting insulation, upgrading motors and drives, and deploying digital controls all cut fuel consumption without sacrificing output. For oil-importing economies, these steps also improve balance-of-payments positions and reduce vulnerability to price spikes, reinforcing the long-standing insight from energy-transition research that efficiency can support smooth economic growth during structural shifts.
Aviation and Shipping Face New Fuel-Switching Rules
Two sectors that have long resisted decarbonization are now subject to binding EU regulations that directly target oil-based fuels. Regulation (EU) 2023/2405, known as ReFuelEU Aviation, mandates sustainable fuel blending requirements with enforcement and reporting obligations for airlines and fuel suppliers operating in European airports. Separately, Regulation (EU) 2023/1805, the FuelEU Maritime rule, requires lower greenhouse gas intensity of energy used on board ships, with penalties and verification rules designed to push vessel operators toward cleaner alternatives.
These regulations matter because aviation and shipping account for a large and growing share of residual oil demand. Even if every new car sold were electric, jet fuel and bunker fuel would keep crude oil entrenched in global energy systems for decades without targeted intervention. The IEA’s Oil 2025 report tracks this dynamic, covering EV sales momentum alongside LNG trucks, high-speed rail expansion, and oil-to-gas and renewables substitution in power generation, including displacement of oil burning in Saudi Arabia. It also quantifies how petrochemicals are becoming the dominant driver of oil demand growth through 2030, a sector where recycling mandates and reduced single-use plastics could apply additional downward pressure.
In aviation and shipping, fuel-switching rules serve a dual purpose. They create guaranteed markets for emerging alternatives such as sustainable aviation fuels and low-carbon marine fuels, and they send long-term price signals that can justify investments in new refineries, pipelines, and vessel designs. The challenge is ensuring that these fuels deliver genuine lifecycle emissions reductions and do not simply shift environmental burdens upstream to land use or feedstock supply chains.
Subsidy Reform and Government Commitment Remain Stalled
One of the most discussed but least acted-upon levers is redirecting fossil-fuel subsidies toward clean energy. The United Nations stresses that technology, capacity, and finance already exist to accelerate the world’s shift to renewable energy, but entrenched subsidies for oil, gas, and coal continue to distort price signals. These subsidies blunt the impact of carbon pricing, undermine the competitiveness of efficiency measures, and lock in high-emitting infrastructure.
Global energy outlooks reinforce this concern. The IEA’s latest world energy analysis highlights that while clean-energy investment is rising, it is not yet sufficient to meet climate goals or fully insulate economies from oil-market volatility. In parallel, the U.S. Energy Information Administration’s long-term projections show that, under current policies, oil and other fossil fuels retain a substantial share of the energy mix for decades, underscoring the gap between stated ambitions and on-the-ground policy implementation.
Security concerns add another layer of urgency. The IEA has argued that a strong focus on oil security remains critical throughout the clean-energy transition, emphasizing that reducing dependence on fossil fuels is the most durable way to cut exposure to supply disruptions. Yet in many countries, short-term responses to price spikes have taken the form of tax holidays, fuel rebates, or expanded subsidies, measures that may ease immediate pressure on households but run counter to long-term transition goals.
Reforming these subsidies is politically difficult. Fuel prices are highly visible, and attempts to raise them have sparked protests from France to Nigeria. That makes it tempting for policymakers to postpone reform and instead rely on incremental efficiency gains or voluntary corporate commitments. But without a deliberate shift in public spending from fossil fuels to clean infrastructure, the transition risks becoming both slower and more expensive, as legacy assets continue to attract capital and delay the tipping point at which renewables and electrification dominate investment flows.
From Incremental Progress to Structural Change
Across EVs, efficiency, aviation, shipping, and subsidy reform, the pattern is consistent: pockets of rapid progress coexist with structural inertia. Electric vehicles are cutting into gasoline and diesel demand faster than many expected, yet heavy transport and petrochemicals keep oil demand resilient. Efficiency measures offer low-cost, immediate savings, but they struggle to capture political attention compared with headline-grabbing megaprojects. Fuel-switching rules in aviation and shipping are finally on the books, but their success depends on scaling up new supply chains and verifying real emissions reductions.
The transition’s next phase will hinge on whether governments treat these tools as marginal add-ons or as core elements of economic and security strategy. Aligning vehicle standards, building codes, industrial policies, and subsidy regimes around a clear trajectory away from oil can turn today’s scattered initiatives into a coherent pathway. The alternative is a prolonged period of half-measures in which clean technologies grow, but not fast enough to prevent renewed oil shocks and mounting climate risks.
The evidence suggests that the technical options are available and increasingly affordable. What remains in doubt is the pace and consistency of policy. If governments can lock in structural changes (phasing down subsidies, tightening standards, and enforcing fuel-switching rules), then the current slowdown in momentum may prove temporary. If not, the world could remain trapped in a volatile middle ground, where dependence on oil persists even as the costs of delay continue to rise.
