Glimmering sea of solar as China expands desert installation

Ordos, China (AFP) Sept 25, 2025
An ocean of blue solar panels ripples across the ochre dunes of Inner Mongolia’s Kubuqi desert, a glittering example of China’s almost inconceivably mammoth energy transition.
Even as other countries have put the brakes on desert solar projects for economic or technical reasons, China — the world’s largest emitter of greenhouse gases — is ploughing ahead.
Desert solar installations are a key part of China’s plans to reach carbon neutrality by 2060. The country’s solar capacity dwarfs global efforts and is so substantial it may even impact local weather patterns.
“Before, there was nothing here… it was desolate,” Kubuqi local Chang Yongfei told AFP as he gestured towards fields of shimmering panels.
The installations are so enormous, they are visible from space.
AFP analysis of satellite images over the last decade shows in Kubuqi alone more than 100 square kilometres of panels have been installed, an area roughly the size of Paris.
On Thursday, China pledged to expand wind and solar capacity to more than six times its 2020 levels, as it tries to slash greenhouse gas emissions by 7-10 percent from peak levels.
The “defining factor” for building in the desert is the availability of otherwise unused land, according to analyst David Fishman.
But the remote, sun-soaked terrain poses formidable challenges.
Sandstorms can degrade panel ventilators, while blistering temperatures reduce the efficiency of solar cells. Sand accumulation can demand scarce water for cleaning.
Kubuqi’s solar panels are designed to counter those obstacles, with self-cleaning ventilators and double-sided cells that allow them to capture light reflected from the ground, according to Chinese state media.
– Infrastructure key –
The distance to energy-hungry urban areas, and the network sophistication required to transport the electricity, has stalled desert projects from North Africa to the United States.
The energy generated in Kubuqi is destined for densely populated Beijing, Tianjin and Hebei, hundreds of kilometres away.
And the growth of solar capacity — overshooting a government target nearly six years early — has not been matched by power grid development.
This causes some energy to be lost, along with congestion on power lines.
Overcoming this requires infrastructure “to effectively allocate and dispatch power around the country without allowing bottlenecks to occur”, said Fishman.
Some places, including Inner Mongolia and neighbouring Ningxia and Gansu, are “restricting new project approvals unless they can explicitly demonstrate” the energy won’t be wasted, he added.
Despite this, in the first half of the year, China installed more solar than the entire solar capacity in the United States as of the end of 2024.
– Coal –
The sheer scale of some desert solar fields might create their own climatic effect, according to the University of Lund’s Zhengyao Lu.
Heat absorption across large areas can change atmospheric flows and have “negative secondary effects”, like rainfall reduction elsewhere, he said.
However, the risks of solar energy “remain minor compared to the dangers of continuing greenhouse gas emissions”, he added.
The solar expansion does not mean fossil fuels have been abandoned, especially in Inner Mongolia, a traditional mining region.
Around Kubuqi, soot-blackened trucks and chimney stacks belching smoke show the industry’s persistence.
China brought more coal power online in the first half of this year than any time since 2016, a report said in August.
The polluting fuel “constitutes a real structural obstacle to the expansion of wind and solar power”, NGO Greenpeace said this summer.
– ‘Good transition’ –
Chang, the local resident, told AFP he used to work in the coal industry.
Now, he runs a hotel made up of huts nestled in the sand dunes, not far from the solar fields.
Views of the shimmering solar cells have gone viral online, as Kubuqi has become a popular domestic holiday destination.
“The transition has been very good for the region,” 46-year-old Chang said.
Quadbike tours, camel rides and dune surfing have become a new source of income for locals.
Chang worries solar expansion might swallow up the whole desert, and with it this new revenue stream.
“But I have confidence the government will leave us a little bit,” he said.
“It should be enough.”
