While the U.S. flounders on environmental action and a growing number of cabinet officials out themselves as climate deniers, China continues to make waves as an emerging leader in this space.

Chinese state media announced this week that the sprawling province of Qinghai in the country’s northwest had run for seven consecutive days entirely on renewable energy. The province, which is larger than Texas, relied only on wind, solar and hydroelectric power from June 17-23, reported Xinhua. These renewable energy sources reportedly provided Qinghai and its population of 5.8 million with 1.1 billion kilowatt hours of electricity — equal to about 535,000 tons of coal.

Qinghai’s fossil fuel-free week was part of a trial that the Chinese government initiated to see if an entire province could successfully achieve zero emissions for an extended period of time. Wang Liming, deputy governor of Qinghai, told China Daily this month that the experiment would set a new global clean energy record.

“It will break the current record of four days held by Portugal,” he said, referring to the four days in May last year when the European nation of 10 million ran on just renewable energy.

As Grist notes, Qinghai is a hub for clean energy in China. Located on the northeastern part of the Tibetan Plateau, the province gets plenty of sun (more than 3,000 hours of daylight every year) and is home to the world’s largest solar farm. Also the location of the headwaters of Asia’s three largest rivers ― the Yellow, Yangtze and Mekong ― Qinghai’s hydropower potential is immense.

“Qinghai is the country’s important warehouse of natural resources and it plays a vital role in the development of the nation’s green industry,” said Miao Wei, China’s minister of industry and information technology, this month, according to China Daily.

China has been positioning itself as a global leader of green energy in recent years. In January, the Chinese government announced plans to spend $360 billion on renewable energy by 2020, an investment they could create 13 million jobs.

With its commitment to clean energy development and reducing its coal consumption, China is set to overachieve the pledges it made in the Paris climate agreement, according to a recent Climate Action Tracker report. Together with India, China’s climate commitments have been so significant that they could offset the negative impacts that President Donald Trump’s climate policies could have on the globe, the report’s authors said.

“Five years ago, the idea of either [China or India] stopping — or even slowing — coal use was considered an insurmountable hurdle, as coal-fired power plants were thought necessary to satisfy the energy demands of these nations. Yet, recent observations show they are now on the way towards overcoming this challenge,” the report said. “This stands in contrast to the decisions of the U.S. administration under President Trump, who appears intent on going in the opposite direction.”
