China’s data centers — the backbone of the country’s fast-growing digital economy — are on track to guzzle more electricity by 2023 than all of Australia last year, said a Greenpeace report published yesterday.
While China leads the world in renewable energy capacity, data centers in the country remain dependent on coal.
Nearly three-quarters of the electricity used by data centers last year was sourced from coal, according to research by Greenpeace East Asia and the North China Electric Power University — emitting 99 million tonnes of carbon emissions.
By 2023, that number could jump to 163 million tonnes.
The appetite for data storage and transmission in China has skyrocketed in recent years, with 800 million online users and a booming tech industry churning out photographs, videos, and online transactions.
“While China’s data center industry has made significant improvements in terms of energy efficiency, the industry’s massive carbon footprint is proof that much more action is needed,” said Ye Ruiqi (葉睿琪), climate and energy campaigner at Greenpeace East Asia, adding that the centers are not aware of their “responsibility to respond to climate change.”
According to the Greenpeace report, electricity consumption from China’s data center industry is projected to increase by 66 percent over the next five years and by 2023, the industry will exceed Australia’s total electricity consumption last year.
By boosting the intake of renewable energy from its current 23 percent to 30 percent, Chinese tech companies could save roughly the equivalent of 10 million round-trip transatlantic flights in carbon emissions, Greenpeace East Asia said.
Brazil, the world’s largest Roman Catholic country, saw its Catholic population decline further in 2022, while evangelical Christians and those with no religion continued to rise, census data released on Friday by the Brazilian Institute of Geography and Statistics (IBGE) showed. The census indicated that Brazil had 100.2 million Roman Catholics in 2022, accounting for 56.7 percent of the population, down from 65.1 percent or 105.4 million recorded in the 2010 census. Meanwhile, the share of evangelical Christians rose to 26.9 percent last year, up from 21.6 percent in 2010, adding 12 million followers to reach 47.4 million — the highest figure
A Chinese scientist was arrested while arriving in the US at Detroit airport, the second case in days involving the alleged smuggling of biological material, authorities said on Monday. The scientist is accused of shipping biological material months ago to staff at a laboratory at the University of Michigan. The FBI, in a court filing, described it as material related to certain worms and requires a government permit. “The guidelines for importing biological materials into the US for research purposes are stringent, but clear, and actions like this undermine the legitimate work of other visiting scholars,” said John Nowak, who leads field
‘THE RED LINE’: Colombian President Gustavo Petro promised a thorough probe into the attack on the senator, who had announced his presidential bid in March Colombian Senator Miguel Uribe Turbay, a possible candidate in the country’s presidential election next year, was shot and wounded at a campaign rally in Bogota on Saturday, authorities said. His conservative Democratic Center party released a statement calling it “an unacceptable act of violence.” The attack took place in a park in the Fontibon neighborhood when armed assailants shot him from behind, said the right-wing Democratic Center, which was the party of former Colombian president Alvaro Uribe. The men are not related. Images circulating on social media showed Uribe Turbay, 39, covered in blood being held by several people. The Santa Fe Foundation
NUCLEAR WARNING: Elites are carelessly fomenting fear and tensions between nuclear powers, perhaps because they have access to shelters, Tulsi Gabbard said After a trip to Hiroshima, US Director of National Intelligence Tulsi Gabbard on Tuesday warned that “warmongers” were pushing the world to the brink of nuclear war. Gabbard did not specify her concerns. Gabbard posted on social media a video of grisly footage from the world’s first nuclear attack and of her staring reflectively at the Hiroshima Peace Memorial. On Aug. 6, 1945, the US obliterated Hiroshima, killing 140,000 people in the explosion and by the end of the year from the uranium bomb’s effects. Three days later, a US plane dropped a plutonium bomb on Nagasaki, leaving abut 74,000 people dead by the
