The environmental and health advantages of electric cars over ICE cars, for instance through reduced local air pollution, are significant. Therefore it can also be seen as an advantage that EVs are getting cheaper, not alone because of increasing competition and government subsidies. Apart from the decreasing purchase costs, also aspects like running costs have to be taken into account when comparing the costs of electric cars. And the running costs of electric cars are way lower than those of conventional cars, studies and experts say. Thus, and probably also because of expected upcoming regulatory measures and rising fuel prices, the sales of electric cars in many countries have risen sharply. Seemingly especially from 2019 to 2020 and from 2020 to 2021. And this although the market share of EVs is already quite high in many countries and regions: the global market share of newly sold EVs 2022 was only about 13% globally and 7% in the US, but already about 23% in Europe, 30% in China, and even about 87% in Norway, to name a few examples.
