IEA Says Internal Combustion Vehicle Sales Peaked in 2017 as EVs Approach 30% of Global Market

IEA Says Internal Combustion Vehicle Sales Peaked in 2017 as EVs Approach 30% of Global Market The 2026 Global EV Outlook projects 23 million electric vehicle sales this year, with BYD building its own export fleet to bypass legacy shipping constraints. The International Energy Agency's 2026 Global EV Outlook declares that sales of internal combustion engine vehicles peaked in 2017. Electric vehicles are expected to account for nearly 30% of global car sales this year, with around 23 million units projected to be sold worldwide, according to the IEA. The number keeps climbing despite economic and policy uncertainties.^2,5 That matters for energy markets because each percentage point of EV penetration displaces crude oil demand. If ICE sales peaked eight years ago and the decline is now structural, oil demand forecasts built on gradual transition timelines are already stale. The IEA's framing is unambiguous: peak ICE is not a forecast. It is a reported fact. BYD is accelerating the shift by building its own export armada, moving to control the logistics chain rather than relying on third-party car carriers. The Driven podcast described legacy automakers as being dragged into a price war they may not be built to win. China's established carmakers, long kept from global markets by the obstacle of competing on internal combustion technology, have found that electrification eliminates that barrier entirely. A host of Chinese startups including Li Auto, Nio, and Xpeng are following Tesla's lead.^5,3 The competitive dynamics are reshaping automotive trade flows into Australia and across Asia-Pacific markets. BYD's vertical integration — from battery cells through to the ships that deliver them — gives it cost advantages that traditional manufacturers cannot match by simply electrifying existing platforms. But the EV surge is creating its own infrastructure bottleneck. Global electricity demand is rising at the fastest pace in 15 years, driven by EVs, AI infrastructure, air conditioning, and advanced manufacturing. The IEA expects annual average power demand growth of 3.6% between 2026 and 2030. Meeting that growth would require boosting annual grid investment by about 50% from $400 billion.⁴ The grid investment gap is already visible. Investments in electricity generation have surged by nearly 70% since 2015, yet spending on power grids has increased at less than half that rate. The IEA's World Energy Outlook warns that this mismatch creates potential bottlenecks that could constrain both EV adoption and broader electrification.¹ The scale of the energy transition's capital requirements is shifting priorities across the economy. Global data centre investment is expected to reach $580 billion in 2025, surpassing the $540 billion being spent on oil supply. That crossover — digital infrastructure outspending upstream petroleum for the first time — signals where capital sees long-term returns.¹ Critical mineral supply chains add another constraint. The IEA warns that one country dominates refining for 19 of 20 key strategic minerals, averaging a 70% global market share. EV battery production depends on these minerals. A supply disruption or export restriction would hit EV manufacturing directly.¹ The demand picture is also shifting geographically. China accounted for 50% of oil and gas demand growth and 60% of electricity demand growth since 2010. The IEA expects emerging economies in South and Southeast Asia to replace China as the primary forces shaping global energy markets. That transition changes where EV adoption matters most for oil demand calculations.¹ On the supply side, 300 billion cubic metres of new annual LNG capacity is expected by the end of the decade, which would reshape gas markets at the same time electrification reshapes power generation. The two trends interact: cheap gas power enables faster EV charging infrastructure buildout in markets without adequate grid capacity, while EV adoption reduces the transport fuel that refineries were built to produce.¹ The signal to watch is whether BYD's export armada reaches Australian and European ports at a pace that forces legacy automakers to cut prices below sustainable margins. If it does, the next wave of oil demand destruction will not come from government mandates or carbon pricing but from consumers choosing cheaper, better cars that happen to be electric.^5,3
