Electric vehicles, or EVs, are on track to dominate global sales of passenger cars and buses by 2040, and to encroach significantly on the market for vans and short-distance trucking, according to the latest forecast from research firm BloombergNEF (BNEF). 

Based on analysis of the evolving economics in different vehicle segments and geographical markets, BNEF's Electric Vehicle Outlook 2019 shows electrics taking up 57% of the global passenger car sales by 2040, slightly higher than it forecast a year ago. Electric buses are set to hold 81% of municipal bus sales by the same date. 

For the first time, BNEF has incorporated in its forecast detailed work on the commercial vehicle market. These projections show electric models taking 56% of light commercial vehicle sales in Europe, the U.S. and China within the next two decades, plus 31% of the medium commercial market. 

Heavy trucks will prove the hardest segment for electrics to crack, with the latter's sales limited to 19% in 2040. Their use case will mostly be in shorter-distance applications. However, conventional heavy trucks on long-haul routes will also face other, non-electric competition - from alternatives using natural gas and hydrogen fuel cells. 

Colin McKerracher, head of advanced transport for BNEF, commented: "Our conclusions are stark for fossil fuel use in road transport. Electrification will still take time because the global fleet changes over slowly but, once it gets rolling in the 2020s, it starts to spread to many other areas of road transport. We see a real possibility that global sales of conventional passenger cars have already passed their peak." 

The role of shared mobility services such as ride-hailing and car-sharing will be important in this evolving picture. These services account for less than 5% of all passenger miles travelled globally at the moment, but this is set to rise to 19% by 2040. The BNEF team does not expect autonomous driving to have an impact on global transport and energy patterns until the 2030s. 

Ali Izadi-Najafabadi, who leads BNEF's coverage of shared mobility, said: "Providers of shared mobility services will choose to go electric faster than private individuals. There are now over a billion users of shared mobility services such as ride-hailing globally. These services will continue to grow and gradually reduce demand for private vehicle ownership." 

The main driver for the electrification trend over the next 20 years will be further sharp reductions in EV battery costs, making electric cars cheaper than internal combustion engine (ICE) alternatives by the mid-to-late 2020s in almost every market, on the basis of both lifetime costs and upfront costs. Since 2010, the average cost of lithium-ion batteries per kilowatt-hour has fallen by 85% on a mixture of manufacturing economies of scale and technology improvements. 

The BNEF report sees China continuing to lead in electric cars, accounting for 48% of all passenger EVs sold in 2025 and 26% in 2040 when other markets are catching up. Europe pulls ahead of the U.S. as the number two EV market globally during the 2020s. Electrification in non-China emerging markets will be much slower, leading to a fragmented global auto market. 

The aggregate increase, however, will be impressive. BNEF expects passenger EV sales to rise from 2 million worldwide in 2018 to 28 million in 2030 and 56 million by 2040. Meanwhile conventional passenger vehicle sales fall to 42 million by 2040, from around 85 million in 2018. Policy support such as fuel economy regulations and China's new energy vehicle mandate are expected to drive the EV market in the next 5-7 years before economics takes over the latter half of the 2020s.
