The International Energy Agency (IEA) expects electric vehicle (EV) sales to rise to a record 17-million in 2024, representing more than one in every five passenger cars sold, but with sales likely to remain highly concentrated in the Chinese, European and US markets. Sales rose by 35% last year to a record level of nearly 14-million units, lifting the number of EVs on the road globally to 40-million, and with battery electric cars accounting for 70% of the electric car stock.
