Global Energy Crisis Could Get Worse, IEA Chief Warns

"The world has never witnessed such a major energy crisis in terms of its depth and its complexity," IEA Executive Director Fatih Birol said Tuesday at a global energy forum in Sydney. "We might not have seen the worst of it yet - this is affecting the entire world," Bloomberg reported.

The whole energy system is in turmoil following the February start of Russia-Ukraine war, with Russia at the time being the biggest oil and natural gas exporter and a major player in commodities, Birol said. Soaring prices are lifting the cost of filling petrol tanks, heating homes and powering industry across the globe, adding to inflationary pressures and leading to deadly protests from Africa to Sri Lanka.

Like the oil crises of the 1970s, which prompted huge gains in fuel efficiency and a boom in nuclear power, the world might see faster adoption of government policies that speed the transition to cleaner energy, Birol said.

In the meantime, security of oil and gas supplies will continue to pose a challenge for Europe, and also for other regions, he said.

"This winter in Europe will be very, very difficult," Birol said. "This is a major concern, and this may have serious implications for the global economy."

The fallout for the global energy sector as the US and allies challenge President Vladimir Putin over the war in Ukraine and seek alternatives to Russian exports have highlighted the need to reduce dependence on fossil fuels, US Energy Secretary Jennifer Granholm told the same forum.

"Our move to clean energy globally could be the greatest peace plan of all," she said. "We want and need to move to clean."

Nations need to guard against switching reliance on one dominant energy supplier - Russia - for another in the shift to clean power, Granholm said. "China has big-footed a lot of the technology and supply chains, and that could end up making us vulnerable if we don't develop our own supply chains," she said.

The nation controls about 80 percent of the global supply chains for solar power, which is set to rise to 95 percent by 2025, according to the IEA.

China dominates much of the lithium-ion battery sector, is a key producer of wind turbines and seeking to quickly build capacity in clean hydrogen technology.

Developments including the US restricting imports of products from China's Xinjiang region and a long-discussed tax in Europe on the import of goods made with high-carbon energy could help diversify the solar supply chain by creating openings for manufacturers such as India, Martin Green, a professor at the University of New South Wales, said at the conference.

"By building resilient clean energy supply chains, we can protect our economies from the shocks of the next crisis," Australia's Climate Change and Energy Minister Chris Bowen said in a speech at the forum. "There is no time to waste."
