COP28: Electric vehicles accelerating end of oil age

But one positive that delegates can point to is the growing fleet of electric vehicles worldwide that is already making a surprisingly big dent in demand.

Growing sales of electric vehicles in recent years have led forecasters to speed up their projections for when global oil use will peak, as public subsidies and improved technology help consumers overcome the sometimes eye-popping sticker prices for battery-powered cars, according to industry experts.

The Paris-based International Energy Agency (IEA), a grouping of 29 industrialised nations, expects world oil consumption to hit its zenith at the end of this decade at 103 million barrels per day (bpd), after making regular adjustments from its 2017 forecast peak of almost 105 million bpd in 2040.

"The game-changer has been the policy support for the shift to electrification quite substantially reducing oil demand from the transportation sector, which has been the key driver of global oil demand growth," IEA energy modeller Apostolos Petropoulos said.

Oil giant BP has pushed forward its global peak oil demand projections, while the governments of both the United States and China - the world's two biggest oil users - have ratcheted back their domestic consumption forecasts.

Transportation is responsible for about 60 per cent of world oil demand, with the US alone accounting for about 10 per cent, according to the IEA.

That share should fall, as the IEA expects EVs will have erased some five million barrels per day of world oil demand by 2030.

Global EV sales now make up about 13 per cent of all vehicle sales and are likely to rise to between 40 per cent to 45 per cent of the market by the end of the decade, according to the IEA.

That is thanks to a blend of increasingly stringent efficiency standards and subsidies introduced by various governments about the world since the 2015 Paris Agreement to hold global warming to within 1.5C above pre-industrial temperatures.

The latest subsidy measures include the US Inflation Reduction Act's $US7500 ($A11,500) tax credit for purchasing a new EV, passed last year and intended to help offset high sticker prices.

While those numbers are big, the IEA has said EV sales would need to be even higher - about 70 per cent of the market by 2030 - to keep to the Paris Agreement target for limiting warming.

Whether sales can scale those heights is uncertain.

EV makers including General Motors, Ford and Stellantis in recent weeks have delayed or scrapped plans to accelerate production amid rising labour costs and signs that higher interest rates are slowing growth in the US.

In the longer term, falling costs for EV batteries have some researchers feeling optimistic.

The rate of future EV adoption is going to depend heavily on EV pricing and the availability of charging stations, according to industry experts.

China has the advantage on both counts.

The average electric vehicle in China cost 31,165 euros ($A51,800) in mid-2023, according to UK research firm JATO Dynamics.

The cheapest EV in China was 8.0 per cent less expensive than the cheapest petrol-powered equivalent car, JATO found.

That is thanks to massive government subsidies and easy availability of rare earths that are crucial in EV production.

EVs have about a quarter of the market in China, and the country is expected to lead global growth.

In the United States, by contrast, the average price for an EV is more than $US53,000 ($A80,850), according to automotive research company Kelley Blue Book - about $US5000 ($7600) more than a petrol-powered car.

The US also lags well behind China in total number of public charging stations.

An industry-funded white paper released in October by the Electrification Institute noted that the US has about 52,000 public charging stations, Europe about 400,000 and China about 1.2 million.

Even so, EVs are expected to grow to up to 50 per cent of new US car registrations by 2030, according to the IEA, as drivers are drawn to the improving technology, falling prices and the prospect of sidestepping volatile prices at gas pumps.

"Change on the political side could delay the transition," said the IEA's Petropoulos, referring to concerns among some EV makers that next year's US election could usher in a new set of policies.

"But ultimately the transition is happening now."
