A 4-gigawatt photovoltaic project built on coal mining subsidence areas in Lingwu in northwest China's Ningxiahui Autonomous Region, is now fully operational, ready to channel green electricity to the country's eastern economic hubs.
It marks the completion of Ningxia's major coal mining subsidence area photovoltaic project, which comprises the 4-gigawatt Lingwu Complex and a 2-gigawatt complex in Ningdong and spans a total area of 180000 mu, or about 12000 hectares.
The six gigawatt project is expected to transmit about 108 billion kilowatt hours of clean electricity annually via an ultra-high-voltage direct current transmission line that connects Ningxia with Zhejiang province, channeling green power from the country's west to economic hubs in the east.
With the launch of full operations, the project can generate enough electricity annually to meet the needs of approximately 72 million households and will save about 324 million tons of standard coal each year, delivering significant economic, social and environmental benefits.
The project utilizes coal reserve areas, subsidence zones, and barren hillsides.
It integrates solar panel power generation, sand control and underpanel plantation and grazing, forging a new path for green development in ecologically fragile regions.
A coal mining subsidence area is an area where the ground subsides and collapses after its underground coal resources are drained.
Efforts have been made to transform such areas into new energy hubs in recent years.

According to the National Bureau of Statistics, China's carbon dioxide emissions per 10000 yuan of GDP fell 5 year-on-year in 2025.
As the country made notable progress in energy conservation and carbon reduction and energy consumption per 10,000 yuan of GDP, excluding energy used as raw materials and non-fossil energy consumption, declined 5.1 percent year on year in 2025 power generation from clean energy sources such as hydro power nuclear power wind power and solar power reached nearly 4.25 trillion kilowatt hours up 14.4% over the previous year.
New energy vehicle production totaled over 1652 million units, marking a 251 increase from a year earlier.
By the end of 2025, the number of new energy vehicles in use had reached 4397 million, an increase of 1257 million from the previous year.
Data from the National Bureau of Statistics shows that environmental quality also continued to improve.
In the 339 cities monitored at or above prefecture level, 726 met the country's national air quality standards.

China has taken a significant step toward regulating its rapidly growing humanoid robotics industry with the release of the country's first national standard system covering the entire industrial chain and life cycle of humanoid robots and embodied artificial intelligence.
The standard system unveiled at the annual meeting of humanoid robots and embodied intelligence standardization in Beijing comprises six key components basic commonality, brain-like and intelligent computing, limbs and components, as well as complete machines and systems.
Application and safety and ethics.
It was developed collaboratively by over 120 research institutions, enterprises and industry users under the organization of the Ministry of Industry and Information Technologies Technical Committee for Humanoid Robots and Embodied Intelligence Standardization.
According to the committee, The brain-like and intelligent computing standards cover critical specifications for embodied intelligences, brain and cerebellum, and intelligent computing regulating the entire data lifecycle and model training and deployment processes.
It added that application standards govern the development, operation and maintenance of humanoid robots across different scenarios, while safety and ethics standards run through the entire industrial life cycle, providing compliance assurance for technological evolution.
The standard system comes after.
China's humanoid robot industry saw significant growth throughout 2025, backed by mid- to long-term plans from national and local governments targeting it as a strategic sector.
Last year is considered China's first year of humanoid robot mass production, with over 140 domestic manufacturers releasing more than 330 different models.
That is according to China's Ministry of Industry and Information Technology.
The new standard system is expected to provide crucial guidance for this rapidly expanding industry, promoting high-quality development through standardized technical requirements and safety protocols.

SciTech museums across China received over 35 million visits during the nine-day spring festival holiday, presenting festive science exhibits that integrated knowledge, fun and cultural experiences to the public.
That is according to the China Science and Technology Museum.
The museum itself welcomed more than 200000 visitors, with themed events celebrating the Year of the Horse, while SciTech museums nationwide tailored their activities to local conditions, launching a variety of science-themed events that blended Chinese zodiac culture, intangible cultural heritage and cutting-edge technologies.
According to the China Science and Technology Museum, it will lead the country's SciTech museums to continue innovating forms of science, popularization and providing better services in 2026, aiming to strengthen the foundations for the nation's self-reliance in science and technology.
That is the end of today's program.
