Core Viewpoint - The "Tian Guang Di Re" technology developed by China National Nuclear Corporation (CNNC) has effectively addressed the high costs of clean heating in rural northern China, with 605 clean energy demonstration projects completed [2][3]. Group 1: Technology Overview - "Tian Guang" refers to solar energy, while "Di Re" primarily refers to shallow geothermal energy and surface air energy. This technology efficiently couples both to achieve comprehensive energy utilization and tiered enhancement [2]. - The system operates by using photovoltaic power for heating and harnessing shallow geothermal energy, significantly improving the efficiency and stability of heating systems, especially in northern regions where soil temperatures are notably higher than outdoor air temperatures in winter [2]. Group 2: Performance and Cost Efficiency - The current 3.0 version of the "Tian Guang Di Re" system boasts an energy conversion efficiency exceeding 95%. Its operational costs are approximately 50% lower than natural gas heating and 20% to 40% lower than traditional coal heating, contributing to a green transformation in rural production and living styles [3]. - Demonstration projects have been successfully implemented in regions such as Ningxia, Gansu, and Inner Mongolia, with positive user feedback. The technology is also expanding its application in Hebei, Inner Mongolia, and Jilin, indicating strong promotion prospects [3]. Group 3: Future Development and Support - To further promote the commercial application of this technology, especially in remote and cold areas, it is essential for the government to provide more attention and support in terms of policy, standards, and market mechanisms [4].

Core Insights - The article highlights the transformation of Hantianling Village in Ningxia, led by Party Secretary Ding Jianhua, who has significantly improved the living conditions and economic prospects of the villagers through various initiatives [1][5]. Infrastructure Development - In 2011, the government initiated a water diversion project, allowing villagers to access Yellow River water, followed by the installation of tap water in 2012, which greatly improved the village's infrastructure [2]. - Roads were hardened, and essential facilities such as schools and health clinics were built, enhancing the overall living conditions in Hantianling Village [2]. Economic Initiatives - Ding Jianhua abandoned a lucrative business to become the village Party Secretary in 2013, focusing on finding suitable industries for income generation, ultimately settling on beef cattle farming [2]. - The village implemented a subsidy program where households could receive 2,000 yuan for purchasing a cow, encouraging villagers to take loans for cattle farming [2]. - Over ten years, Ding has guaranteed loans exceeding 600 million yuan for villagers, helping them overcome financial difficulties [2]. Agricultural Advancements - In 2017, support from China National Nuclear Corporation (CNNC) brought funding and technology to the village, leading to the establishment of a standardized beef cattle breeding park with over 900 cattle [3]. - The village has also adopted innovative technologies such as geothermal heating, significantly reducing energy costs for residents [4]. Income Growth - The average annual income for impoverished households in Hantianling Village reached 16,295 yuan in 2024, a fourfold increase since 2011 [4]. - Villagers are diversifying their income through various means, including livestock farming and crop cultivation, with some families earning around 20,000 yuan from growing peppers [4]. Community Transformation - The overall morale and confidence of the villagers have improved, with better access to education and healthcare, leading to a positive change in their outlook on life [5]. - The village plans to rename itself from Hantianling to "Hantianling," symbolizing the significant changes and the villagers' relentless efforts [5].
