中国在沙漠，悄悄干了件大事

Core Points - China is constructing the world's largest solar and wind power base in the Kubuqi Desert, with a planned total installed capacity of 450 million kilowatts, equivalent to the total output of 20 Three Gorges Dams [4][2][12] - The project aims to transform barren desert areas into productive land by integrating agriculture with renewable energy production, showcasing a unique "photovoltaic + agriculture" model [24][26][28] - The initiative is part of China's broader strategy to utilize its vast desert areas for renewable energy generation, addressing both energy needs and environmental restoration [17][20][29] Group 1 - The Kubuqi Desert solar power station has already converted 27,000 acres of desert into an oasis, demonstrating the potential for large-scale solar energy projects in arid regions [8][6] - The solar power station in Qinghai's Talatan covers an area of 609 square kilometers, comparable to the entire land area of Singapore, and has significantly improved local environmental conditions [10][12] - The investment in the Kubuqi Desert project exceeds 80 billion yuan, highlighting the scale and ambition of China's renewable energy initiatives [4][2] Group 2 - China's photovoltaic capacity has been steadily increasing, with a cumulative installed capacity that ranks first globally for nine consecutive years, accounting for over 70% of the world's production of polysilicon, wafers, and cells [31][20] - The "photovoltaic + agriculture" model not only generates clean energy but also contributes to local economic development by integrating crop cultivation and livestock farming into solar power projects [26][28] - The approach of using solar panels to create microclimates for plant growth has proven effective in desert areas, allowing for sustainable land use and environmental restoration [23][24]
