Electric cars will outsell internal combustion engine (ICE) vehicles within two decades as battery prices plunge, and account for 33% of all the light-duty vehicles on the road, according to new research published by Bloomberg New Energy Finance.
The Bloomberg New Energy Finance (BNEF) forecast says adoption of emission-free vehicles will happen more quickly than previously estimated because the cost of building cars is falling so fast. The seismic shift will see cars with a plug account for a third of the global auto fleet by 2040 and displace about 8 million barrels a day of oil production—more than the 7 million barrels Saudi Arabia exports today.
The forecast, put together by the advanced transport team at BNEF, draws on detailed analysis of likely future reductions in price for lithium-ion batteries and of prospects for the other cost components in EVs and internal combustion engine, or ICE, vehicles. It also factors in the rising EV commitments from automakers and the number of new EV models they plan to launch.
The central finding of the research is that the EV revolution is going to hit the car market even harder and faster than BNEF predicted a year ago. The team now estimates that EVs will account for 54% of all new light-duty vehicle sales globally by 2040, not the 35% share it forecast previously. By 2040, EVs will be displacing 8 million barrels of transport fuel per day and adding 5% to global electricity consumption.
Colin McKerracher, lead advanced transport analyst at BNEF, said: “We see a momentous inflection point for the global auto industry in the second half of the 2020s. Consumers will find that upfront selling prices for EVs are comparable or lower than those for average ICE vehicles in almost all big markets by 2029.”
The forecast shows EV sales worldwide growing steadily in the next few years, from the record 700,000 seen in 2016 to 3 million by 2021. At that point, they will account for nearly 5% of light-duty vehicle sales in Europe, up from a little over 1% now, and for around 4% in both the U.S. and China.
However, the real take-off for EVs will happen from the second half of the 2020s when, first, electric cars become cheaper to own on a lifetime-cost basis than ICE models; and, second – arguably an even more important moment psychologically for buyers – when their upfront costs fall below those of conventional vehicles.
The key component of an EV – the battery – is set to plunge in price, building on recent, remarkable cost declines. Since 2010, lithium-ion battery prices have fallen 73% per kWh. Manufacturing improvements and more than a doubling in battery energy density are set to cause a further fall of more than 70% by 2030.
The result will be rapidly rising market shares for electric vehicles in the biggest markets, even with oil prices staying low. BNEF sees them accounting for nearly 67% of new car sales in Europe by 2040, and for 58% in of sales in the U.S. and 51% in China by the same date. Countries that have made early progress in EV uptake are expected to be among the leaders in 2040, including Norway, France, and the U.K. Emerging economies such as India are forecast not to see significant EV sales until the late 2020s.
Jon Moore, chief executive of BNEF, said that that growth in EV market share “will come about during a time when the power system is also undergoing a revolution, towards cleaner, more distributed generation. This means that not only do EVs surge, but their emissions profile improves over time.”
BNEF’s forecast is based squarely on the relative economics of EVs and ICE cars. It assumes that current policies to encourage EV take-up continue until their scheduled expiry, but does not assume the introduction of any fresh measures. BNEF analyzed the auto market not just by country but also by segment, encompassing everything from small run-arounds to SUVs and large family cars.
Salim Morsy, senior analyst on BNEF’s advanced transport team and lead author of the report, commented: “There is a credible path forward for strong EV growth, but much more investment in charging infrastructure is needed globally. The inability to charge at home in many local and regional markets is part of the reason why we forecast EVs making up just over a third of the global car fleet in 2040, and not a much higher figure.”
The team incorporated work into their EV forecast work on two other hot topics in the transport revolution – autonomous vehicles, and ride sharing. It concluded that the impact of autonomous driving will be limited in the next 10 years but will play an increasing role in the market after 2030, with 80% of all autonomous vehicles in shared applications being electric by 2040 due to lower operating costs.
