Across the golden dunes of Inner Mongolia’s Kubuqi desert, an immense sea of blue solar panels now glitters under the scorching sun — a striking symbol of China’s unprecedented clean energy drive.
While many nations have scaled back desert-based solar projects due to economic and technical hurdles, China — still the world’s largest greenhouse gas emitter — is pushing ahead with record-breaking installations. Solar farms like those in Kubuqi are at the heart of Beijing’s pledge to achieve carbon neutrality by 2060, and the scale is so vast that experts believe they may even influence local climate systems.
“Once this place was nothing but barren sand,” said local resident Chang Yongfei, pointing toward the sprawling fields of panels. Today, the solar farms stretch over 100 square kilometres — nearly the size of Paris — and can even be spotted from space.
This week, Chinese authorities vowed to expand solar and wind capacity to six times its 2020 levels, aiming to cut emissions by 7–10 percent from their peak. For China, deserts offer an advantage that few other regions can match: vast expanses of unused land. But they also come with serious challenges.
Sandstorms can erode equipment, extreme heat lowers solar cell efficiency, and cleaning sand-clogged panels consumes scarce water. To address this, developers have turned to innovations such as double-sided panels that capture reflected sunlight and self-cleaning ventilation systems.
Yet distance remains a problem. Electricity generated in Kubuqi must travel hundreds of kilometres to Beijing, Tianjin, and Hebei, straining transmission grids that lag behind the pace of new installations. In fact, China has already surpassed its solar capacity targets years ahead of schedule, but bottlenecks in the power network mean some energy is wasted. Regulators in Inner Mongolia, Ningxia, and Gansu now demand proof that new projects won’t suffer the same fate before granting approval.
Even so, China’s progress dwarfs that of other countries. In just the first half of this year, it installed more solar power than the United States has in total. Researchers caution, however, that covering vast desert landscapes with panels could alter atmospheric flows, potentially reducing rainfall in nearby areas. Still, the risks are seen as minor compared to the escalating damage from fossil fuels.
And fossil fuels are far from gone. Inner Mongolia, historically a coal stronghold, continues to expand coal-fired capacity — more than at any time since 2016. Greenpeace has warned that coal’s dominance remains a structural barrier to renewable growth.
For people like Chang, the shift has been personal. Once employed in coal, he now runs a desert lodge catering to tourists who flock to see the futuristic solar fields shimmering across the sands. Camel rides, quadbike tours, and dune surfing have created new livelihoods, though he worries the relentless expansion of panels might overrun the desert’s tourist appeal.
Still, he remains optimistic. “I believe the government will leave us a little desert,” he said with a smile. “That will be enough.”
