Core Viewpoint - Xinjiang is transforming its abundant "wind and solar" resources into a green engine for high-quality development, contributing to China's modernization narrative [1][3]. Group 1: Renewable Energy Resources - Xinjiang has approximately 4.2 billion kilowatts of solar energy resources, accounting for about 27% of the national total, and around 1 billion kilowatts of wind energy resources, making up about 18% of the national total [3]. - As of September 15, the renewable energy generation in Xinjiang reached 100.94 billion kilowatt-hours, a year-on-year increase of 17.2%, with solar power contributing 41.24 billion kilowatt-hours (up 39.2%) and wind power 59.7 billion kilowatt-hours (up 6%) [3]. - By the end of July this year, Xinjiang's installed renewable energy capacity reached 134 million kilowatts, with cumulative electricity exports of 278.511 billion kilowatt-hours, accounting for nearly 30% of total exports [3]. Group 2: Project Developments - The 500,000-kilowatt photovoltaic desertification control demonstration project in the Taklamakan Desert can supply 963 million kilowatt-hours of clean electricity annually, equivalent to saving 289,600 tons of standard coal and reducing carbon dioxide emissions by approximately 805,100 tons [5]. - The 1 million-kilowatt wind farm in Ruoqiang County has generated 850 million kilowatt-hours of electricity as of mid-September, with full capacity expected to be connected to the grid by December 26, 2023 [5][6]. - The National Development and Reform Commission and the National Energy Administration have emphasized the construction of renewable energy bases in desert and arid regions, including Xinjiang, as part of the 14th Five-Year Plan [6]. Group 3: Ecological and Economic Benefits - The "desertification control + agricultural-solar complementary" model in the Loopu project has transformed previously barren land into productive areas, with 1,800 acres of alfalfa harvested [9][10]. - The project has also led to a significant reduction in sandstorm occurrences and an increase in local biodiversity, demonstrating the dual benefits of ecological protection and economic development [10]. - The integration of renewable energy projects with local economic activities has resulted in increased income for local residents, with per capita disposable income in He Ya Village rising from 2,300 yuan in 2014 to 22,900 yuan in 2024 [13][14]. Group 4: Policy Support and Community Development - Xinjiang has implemented various policies to support renewable energy and ecological restoration, including financial incentives for new technology projects [10]. - The collaboration between energy companies and local governments has facilitated community development, with significant investments in infrastructure and education [14][15]. - The ongoing support from energy enterprises has led to improved living conditions and economic opportunities for local residents, contributing to the overall goal of rural revitalization [12][14].
