Gold in the Desert: The Miracle of Chinas Solar Power

When we think of deserts, we often imagine desolate, dry, and endless landscapes. This seemingly barren land was once considered a no mans zone, and even with the advancements of technology today, crossing a desert remains a risky endeavor. However, in recent years, China has made remarkable achievements in desert management and the development of new energy, one of which is the construction of large-scale solar power stations in deserts. This not only provides China with a continuous supply of clean energy but also marks the beginning of a new chapter in desert ecological management.

Solar Power: Gold in the Desert

As a populous nation, China has a massive energy demand. With the rapid development of modern technology, electricity has become an indispensable part of modern life. In addition to traditional power generation methods like thermal power, wind power, and hydropower, solar power and nuclear power have gradually become important supplementary energy sources. Among them, solar photovoltaic power generation has attracted considerable attention due to its clean, renewable, and safe advantages.

The core of solar photovoltaic power generation technology lies in utilizing the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. As early as 1883, the worlds first solar cell was born. Although its power generation efficiency was only 1% at the time, it foreshadowed the immense potential of photovoltaic technology. In 1954, scientists at Bell Labs in the United States made a breakthrough in the field of photovoltaic power generation, marking the advent of the solar cell technology era.

Entering the 1970s, along with the pace of Chinas reform and opening-up, the industrialization process accelerated continuously, and energy shortages became increasingly prominent. To address this energy problem, Chinese scientists actively devoted themselves to researching solar photovoltaic power generation. After decades of relentless efforts, China has achieved a series of significant advancements in the photovoltaic power generation field.

Deserts: The Ideal Choice for Solar Power

In areas with abundant sunshine, solar photovoltaic power generation achieves higher efficiency. Deserts, as one of the regions with the richest solar energy resources on Earth, become the ideal choice for photovoltaic power generation.

The deserts in northwestern China are located at high altitudes with thin air. When sunlight passes through the atmosphere, energy loss is relatively less. Combined with long hours of sunshine, these characteristics provide excellent conditions for photovoltaic power generation. At the same time, deserts are sparsely populated with relatively flat terrain, offering convenience for constructing photovoltaic power stations. More importantly, deserts possess abundant land resources, providing ample construction space for photovoltaic power stations. Experts estimate that utilizing only 1% of Chinas total desert area could meet the countrys electricity demand.

Challenges and Breakthroughs: Win-Win for Desert Management and Solar Power

Despite the abundant solar energy resources found in deserts, constructing photovoltaic power stations also presents numerous challenges. The most immediate concern is the issue of wind and sand. Deserts experience constant wind and sandstorms, with sand particles swirling in the wind, causing severe damage to photovoltaic panels. As semiconductor devices, photovoltaic panels are quite fragile. Once scratched by sand particles, their efficiency declines, and they may even experience electrical leakage or collapse.

To overcome the challenges posed by wind and sand, Chinese scientists and engineers actively explore solutions. In the early days, people tried using afforestation to manage wind and sand. However, saplings require a long time to grow into large trees, and trees can also block sunlight, affecting the efficiency of photovoltaic power generation.

Eventually, the workers came up with a clever method using grass instead of trees. Grass has strong vitality and can rapidly grow with a little water, forming lush grasslands in a short time. Before constructing photovoltaic panels, workers first sow grass seeds in the desert. Soon, patches of green dotted the barren desert.

However, the growth rate of grass exceeded expectations, quickly forming grasslands that reached half the height of a person, affecting the power generation of photovoltaic panels. In autumn and winter, the dry grasslands also posed a fire risk. If a fire occurred, the consequences would be disastrous.

Facing this new challenge, workers once again displayed their ingenuity and thought of a sheep grazing solution. They introduced herders into the photovoltaic power station to graze their cattle and sheep, which effectively controlled the growth of the grasslands while helping herders increase their income, achieving a win-win outcome.

From Desert to Oasis: The Ecological Benefits of Chinas Solar Power

The construction of photovoltaic power stations not only provides China with clean energy but also has a positive impact on improving the deserts ecological environment.

The construction of photovoltaic panels provides shade for grasslands, reducing water evaporation and promoting grass growth. At the same time, photovoltaic panels absorb some heat during power generation, lowering the surface temperature and further improving the deserts microclimate. Even more surprisingly, a virtuous cycle has formed between photovoltaic panels and grasslands. During the day, photovoltaic panels block direct sunlight from reaching the ground, reducing water evaporation. At night, water vapor evaporated from the grasslands condenses into dew, falling onto the photovoltaic panels and eventually returning to the Earth, nourishing the grasslands.

Over time, the once desolate desert has gradually transformed into an oasis. Rows of photovoltaic panels shine under the sun, grasslands thrive, and cattle and sheep graze, creating a vibrant scene.

From Tarateng to Kubuqi: The Scaled Development of Chinas Solar Power

China has accumulated extensive experience in developing solar power in desert areas and has applied it throughout the country, promoting the scaled development of photovoltaic power generation.

In 2012, construction began on the Tarateng Photovoltaic Power Station in Qinghai. After several years of development, its power generation capacity has expanded fivefold, reaching an installed capacity of 15,000 MW. Its annual power generation exceeds 1 million kWh. Apart from power generation, the Tarateng Photovoltaic Power Station has also contributed to local wind and sand control efforts, raising over 20,000 cattle and sheep and creating numerous job opportunities.

In 2021, the Kubuqi Photovoltaic Desertification Control Project, jointly invested by Three Gorges Energy and Elion Resources, officially commenced. Covering an area of approximately 100,000 mu (approximately 6,667 hectares), the project is expected to cost over 10 billion yuan and is the worlds largest Sago wind and photovoltaic base project. After two years of construction, the project successfully achieved grid connection, generating 450 million kWh of electricity annually, equivalent to the power output of 20 Three Gorges Dams.

Chinas Photovoltaic: Leading Global Development

In recent years, the number of photovoltaic power stations in China has continuously increased, and the solar energy industry has flourished. Chinas research achievements in solar power have become world-leading. Based on its own practical experience, China has comprehensively surpassed the United States in the solar power generation field, becoming the global leader in the photovoltaic industry.

In 2023, the scale of Chinas photovoltaic industry continued to expand, with total industry output exceeding 1.7 trillion yuan. Amidst the increasingly severe energy challenges, China has blazed a new trail, seizing the opportunity of solar photovoltaic power generation to effectively alleviate the energy shortage problem.

As technology continues to advance, photovoltaic power generation technology will have even greater development potential in the future. China, with its leading technology and rich experience, will provide solutions for wind and sand control and energy conservation and emission reduction to other countries worldwide, contributing to global sustainable development.

Conclusion: Gold in the Desert Illuminates the Future

The once desolate deserts, under Chinas transformation, have become lush green oases, and the electricity generated by photovoltaic panels illuminates countless homes. The achievements China has made in solar power generation have significant meaning for adjusting our countrys energy structure. In the future, China will continue to showcase its strength as a major country, make even greater contributions to global wind and sand control, energy conservation, and emission reduction, and create a more beautiful future for the world.
