China's Diminishing Reliance on Oil: The Electrifying Impact of Electric Vehicles on Fuel Consumption
Picture this: The world's biggest oil consumer is starting to wean itself off the black stuff, thanks to a fleet of silent, emission-free cars zooming onto the roads. It's a game-changer that's reshaping energy landscapes and sparking debates on everything from global trade to environmental dreams!
From 2005 to 2024, China's oil usage skyrocketed, effectively doubling in volume. This surge made the nation the top importer of crude oil globally, responsible for more than half of the worldwide uptick in oil demand. But after two decades of relentless growth, something shifted around 2019: Oil consumption in transportation began to stabilize, and in 2024, it even dipped slightly for the first time annually. This pivotal change owes much to the explosive rise of electric vehicles (EVs), which are battery-powered cars that run on electricity instead of gasoline, producing zero tailpipe emissions. For beginners, think of EVs as the eco-friendly cousins to traditional gas-guzzlers—they plug in like your phone to recharge, cutting out fossil fuels entirely. This shift fits neatly into China's grand plan to ramp up its technological independence and sidestep vulnerabilities from overseas supply chains, especially as the planet's energy and manufacturing networks undergo a major realignment (de Soyres and Moore 2024).
To visualize this, take a look at Figure 1, which illustrates global crude oil consumption by country. (Source: Statistical Review of World Energy 2025, Energy Institute.) It highlights how China's appetite for oil has been outsized, but the tide is turning.
And this is the part most people miss: EVs aren't just a trendy gadget; they could slash oil use by tens of millions of barrels daily in just 20 years, as forecasted by Cherif et al. (2017). This would redraw oil trade routes and potentially lower prices worldwide. Yet, real-life savings hinge on practical factors like easy access to charging stations and how people actually drive—urban commuters might save more than long-haul truckers, for instance. Studies like Bushnell et al. (2022), Rapson and Muehlegger (2023), and Gessner et al. (2025) back this up with data from everyday usage.
China is at the heart of this revolution. Through smart government policies, hefty subsidies—think tax breaks or direct payments to buyers that make EVs cheaper upfront—and seamless teamwork between automakers and battery makers, they've created the largest EV market and production hub on the planet (Ezell 2024, Bickenbach et al. 2024, DiPippo et al. 2022). This approach boosts China's economic clout internationally, affecting how companies compete and how global supply chains operate (D’Orazio et al. 2024, Kee and Xie 2024, Gourinchas et al. 2024, Arezki and Van der Ploeg 2025). By 2024, EVs snagged over 25% of new car sales in China and made up 11% of all vehicles on the road—only Norway has a higher EV share, and Chinese-made EVs dominate about 60% of the world's EV total. (For clarity, Table 1 defines vehicle types, and Figure 2 compares EV stocks and growth internationally. Source for Table 1: IEA. Source for Figure 2: CEIC; Our World in Data and IEA. Notes: In the left panel, 'Other' covers diesel, natural gas, LPG, and alternative fuels. The right panel's green bars show each nation's EV portion of its vehicle fleet in 2024, orange bars depict EV growth from 2014 to 2024, and blue bars indicate each country's slice of the global EV fleet that year.)
But here's where it gets controversial: Is China's aggressive EV strategy a fair boost to innovation, or does it unfairly subsidize dominance, potentially squeezing out competitors? Some argue these policies level the playing field for clean tech, while others see them as protectionism that distorts markets.
To gauge EVs' influence on China's gasoline needs, our recent study (Bencivelli et al. 2025) uses a dynamic model that tracks passenger vehicle stocks, separating internal combustion engine (ICE) cars—which run on gasoline—and EVs, while factoring in their fuel use. This tool: (i) calculates EV-related gasoline cuts from 2015 to 2024 by pitting real consumption against a hypothetical 'No EV Adoption' world where EVs never took off; (ii) forecasts gasoline needs through 2040 under different EV rollout speeds; and (iii) evaluates lasting fuel savings by contrasting these with a 'Constant EV Adoption' scenario, where the EV share in new sales stays fixed at 2024 levels (about 48%). We drew on yearly EV sales data and vehicle stocks, and calibrated scrappage rates (how quickly cars are retired) using Nguyen-Tien et al. (2025).
Gasoline Savings Already Achieved: 2015-2024
During this period, China's EV boom picked up steam, trimming gasoline use noticeably. Figure 3 juxtaposes real Chinese gasoline consumption (solid blue line on the left axis) with the 'No EV Adoption' hypothetical (dashed blue line on the left axis), and plots the gap between them (blue bars on the right axis) in millions of barrels per day (mb/d). (Sources: CEIC, IEA, Our World in Data. Notes: Solid blue lines show actual data, dashed for the counterfactual; bars indicate the difference in mb/d.)
By 2020, EVs had shaved off 0.1 mb/d of gasoline—about 3% of that year's total. This savings grew steadily, hitting 0.43 mb/d in 2024, or 12% of China's annual gasoline use then. That's like dodging 67.5 million tons of CO2 emissions that year, equal to roughly 0.6% of China's overall CO2 output in 2023. For context, this rivals the 1% emissions drop seen during strict 'Zero-COVID' lockdowns, showing EVs' real environmental punch.
Looking Ahead: Long-Term Projections for 2025-2040
To explore lasting impacts, we compare EV paths against a 'constant adoption' baseline, which locks in the 2024 new car EV share at around 48% and projects China's vehicle fleet to 2040, tying it to gasoline demands and CO2 footprints.
Figure 4 illustrates various EV adoption scenarios and their effects on China's gasoline needs from 2025-2040. (Sources: CEIC, IEA, Our World in Data, OIES. Notes: Past data in solid black lines.)
We model different EV penetration speeds—slow, medium, and fast—based on rising EV portions in new sales. We also include a 'no EV adoption' extreme for comparison.
Panel (a) depicts fleet makeups by 2040: EVs would comprise about 60% of vehicles under 'fast adoption,' 50% under 'medium' or 'slow,' and 30% under the 'constant' baseline. The crossover point, where EVs surpass ICE vehicles, happens in 2037 for fast growth and 2039 for slow; otherwise, gas cars dominate through 2040.
Panel (b) shows gasoline demand paths. 'Fast adoption' peaks demand as early as 2025 due to swift ICE replacements. Medium peaks in 2027, slow in 2028 before declining. The difference between 'fast adoption' (green line) and 'constant' (grey line) reveals growing annual savings: about 1.0 mb/d by 2035 and 1.7 mb/d by 2040. To put that in perspective, 2040's savings could equate to slashing 267 million tons of CO2—around 2.3% of China's 2023 emissions—helping global climate goals immensely.
Wrapping It Up
Our research points to China's swift EV embrace as a key force behind its recent oil trends. In just 2024, EVs offset roughly 0.43 million barrels of gasoline daily. Projections suggest this could multiply fourfold by 2040 with quicker shifts. These insights ripple outward: For oil markets, they weaken a major growth driver of the last twenty years. For the energy shift, they demonstrate how robust EV uptake can transform China's fuel habits, yielding big emission cuts.

What do you make of all this? Should governments worldwide follow China's lead on EV subsidies to accelerate the shift away from oil, or does that risk unfair trade practices?
