“Now we have an oil crisis, a gas crisis and an electricity crisis at the same time,” Fatih Birol, head of the International Energy Agency watchdog group, told Der Spiegel in an interview published this week. “This energy crisis is much bigger than the oil crises of the 1970s and 1980s. And it will probably last longer.”

The global economy has largely been able to withstand surging energy prices so far. But prices could continue to rise to unsustainable levels as Europe attempts to wean itself off Russian oil and, potentially, gas. Supply shortages could lead to some difficult choices in Europe, including rationing.

Joe McMonigle, secretary general of the International Energy Forum, said he agrees with this depressing forecast from the IEA.

“We have a serious problem around the world that I think policymakers are just waking up to. It’s kind of a perfect storm,” McMonigle, whose group serves as a go-between for energy producing and consuming nations, told CNN in a phone interview.
