POWER shortages are turning out streetlights and shutting down factories in China. The poor in Brazil are choosing between paying for food or electricity. German corn and wheat farmers can’t find fertilizer, made using natural gas. And fears are rising that Europe will have to ration electricity if it’s a cold winter.

The world is gripped by an energy crunch — a fierce squeeze on some of the key markets for natural gas, oil and other fuels that keep the global economy running and the lights and heat on in homes.

Heading into winter, that has meant higher utility bills, more expensive products and growing concern about how energy-consuming Europe and China will recover from the COVID-19 pandemic.

The biggest squeeze is on natural gas in Europe, which imports 90 percent of its supply — largely from Russia — and where prices have risen to five times what they were at the start of the year, to 95 euros (US$110.57) from about 19 euros per megawatt hour.

It’s hitting the Italian food chain hard, with methane prices expected to increase sixfold and push up the cost of drying grains. That could eventually raise the price of bread and pasta at supermarkets, but meat and dairy aisles are more vulnerable as beef and dairy farmers are forced to pay more for grain to feed their animals and pass the cost along to customers.

“From October we are starting to suffer a lot,” said Valentino Miotto of the AIRES association that represents the grain sector.

Analysts blame a confluence of events for the natural gas crunch.

Demand rose sharply as the economy rebounded from the pandemic, while a cold winter depleted reserves. Europe’s chief supplier, Russia’s Gazprom, held back extra summer supplies beyond its long-term contracts to fill reserves at home for winter.

China’s electricity demand has come roaring back, vacuuming up limited supplies of liquid natural gas, which moves by ship, not pipeline. There also are limited facilities to export natural gas from the United States.

Costlier natural gas has even pushed up oil prices because some power generators in Asia can switch from using gas to oil-based products. U.S. crude is over US$83 per barrel, the highest in seven years, while international benchmark Brent is around US$85, with oil cartel OPEC and allied countries cautious about restoring production cuts made during the pandemic.

The crunch is likely short term but it’s difficult to say how long higher fossil fuel prices will last, said Claudia Kemfert, an energy economics expert at the German Institute for Economic Research in Berlin.

But “the long-term answer that has to be taken out of this is to invest in renewables and energy saving,” she said.

The European Union’s executive commission urged member nations last week to speed up approvals for renewable energy projects like wind and solar, saying the “clean energy transition is the best insurance against price shocks in the future and needs to be accelerated.”

In the meantime, some gas-dependent European industries are throttling back production. German chemical companies BASF and SKW Piesteritz have cut output of ammonia, a key ingredient in fertilizer.

That left Hermann Greif, a farmer in the village of Pinzberg in Germany’s southern Bavaria region, unexpectedly empty handed when he tried to order fertilizer for next year.

“There’s no product, no price, not even a contract,” he said. “It’s a situation we’ve never seen before.” (SD-Agencies)
