通讯：科技赋能 中国煤炭大市绿色发展变迁记

Core Viewpoint - The article highlights the transformation of Ordos City, a major coal-producing area in China, towards green development through technological empowerment, particularly in combating desertification and promoting renewable energy sources [1][2]. Group 1: Desertification Control - Ordos City has implemented advanced technologies to combat desertification in the Kubuqi Desert, achieving a governance rate increase from 4.6% in the early 21st century to 40% [2]. - The use of robots and advanced machinery has significantly improved the efficiency of planting and sand control, with robots planting at a rate of one seedling every five seconds and a solid sand vehicle sowing 2,000 plants per hour, which is 80 times more efficient than manual labor [2]. - The Kubuqi Desert ecological governance area has been recognized by the United Nations as a "Global Desert Ecological Economic Demonstration Zone" [2]. Group 2: Renewable Energy Development - The Ujier Wind Farm in Ordos features large wind turbines and a solar power station with 196,300 photovoltaic panels, generating 2 billion kilowatt-hours of green electricity annually, saving approximately 680,000 tons of standard coal and reducing carbon dioxide emissions by about 1.65 million tons [2][4]. - Ordos City is developing a large-scale wind and solar energy base, with a total potential of 140 million kilowatts, equivalent to the capacity of 6.2 Three Gorges Hydropower Stations [4]. - By 2024, Ordos is expected to add over 10 million kilowatts of new energy capacity, bringing the total installed capacity to 21.24 million kilowatts, which accounts for nearly one-sixth of Inner Mongolia's total renewable energy capacity [4]. Group 3: Technological Innovation - Ordos has established several research institutions focused on sustainable development, including the Ordos Energy Research Institute and the Ordos Carbon Neutral Research Institute, contributing to significant technological advancements [5]. - The city has attracted high-level innovative talent, enhancing its innovation capabilities and ranking among the top 100 cities in China for innovation [5].
