Rocketing electricity prices are increasing the cost of driving electric vehicles in Europe, in some cases making them more expensive to run than gas-powered models—a change that could threaten the continent’s electric transition. Electricity prices have soared in the wake of Russia’s invasion of Ukraine, in some cases eliminating the cost advantage at the pump that EVs have enjoyed. In some cases, the cost difference between driving both types of cars 100 miles has become negligible. In others, EVs have become more expensive to fuel than equivalent gasoline-powered cars.
