Under these circumstances, Europe must expect that the gas storage facilities will only be 65 percent full at the beginning of winter 2023 and not 95 percent like this year. “The current cushion from the filled gas storage facilities, the recent drop in prices and the mild temperatures should not lead to overly optimistic conclusions,” said IEA chief Fatih Birol. The agency, which advises developed countries on energy policy issues, called on governments to do everything they can to reduce demand for gas. This year, Russia delivered 60 million cubic meters of gas to Europe.
