Indeed, electrical generation in Europe remains high right now due to the disruption in the gas market. That's newsworthy and deserves coverage, but it's got nothing to do with "Electric Vehicles".
Also, article spins badly trying to conflate charging at DC fast chargers with "charging an EV". In fact most EV charging happens at home at residential rates, not at fast chargers which need to charge a premium to provide high-amperage service to remote locations. FWIW: my Model Y in the west coast of the USA (an area much more heavily reliant on long road trips and thus fast charging) has received just 27% of its total energy from superchargers. I'd expect British cars to use them even less.
