As the world's largest developing country, development remains China's top priority. However, given the dual pressures of energy resources and the environment, China's development must adhere to the principles of low energy intensity and total control. Based on this, it highlights the significance and necessity of promoting final energy efficiency improvement and regional energy development in China—on the supply side, achieving optimal integration of various energy forms and grades; on the demand side, reducing energy demand, matching energy grades with temperature requirements, utilizing energy in a stepped manner, and complementing multiple energy sources. Reasonably lowering the grade requirements for energy, maximizing the utilization of renewable energy and various low-grade energy sources, and transforming energy consumption patterns to enhance energy efficiency. Currently, energy science and technology innovation is accelerating, and a new round of energy technology revolution is thriving, with new energy production and consumption models characterized by intelligence beginning to emerge. Smart grids are developing rapidly, distributed intelligent energy supply systems are being applied in industrial parks, urban communities, public buildings, and private residences, the industrialization of new energy vehicles is accelerating, more and more energy-consuming entities are participating in energy production and market transactions, and new smart energy business forms based on intelligent energy terminals and multi-energy complementation are taking shape, becoming an important approach to promote the large-scale application of distributed renewable energy. China is the world's largest energy producer and consumer, as well as the largest producer and consumer of new energy. The 19th National Congress of the Communist Party of China in 2017 proposed the goal of building a clean, low-carbon, safe, and efficient energy system, marking a new stage for China's energy development, shifting from total expansion to quality improvement and efficiency enhancement. The target of peaking carbon emissions by 2030 and the vision of achieving carbon neutrality by 2060 have led China to conduct extensive practices in final energy efficiency improvement and distributed energy application. The promotion of these projects holds significant importance for both China and the world.

China, or the global community, is currently entering an era of major transformation. The path of energy transition remains arduous, and important issues such as further reducing the proportion of fossil fuels, improving energy system efficiency, and providing reliable and affordable energy to users still need to be addressed. For this reason, research on smart final energy and distributed energy coupling is particularly important.

The project will analyze the current status, development trends, and typical cases of final energy utilization in China and around the world. By combining analysis of key distributed energy technologies and innovative practice cases, such as conducting renewable energy utilization planning studies at the urban level, formulating building energy consumption standards, and establishing building energy management platforms, it will provide support for constructing China's clean, low-carbon, safe, and efficient modern energy system. It will also offer new ideas and demonstrate new models for achieving the United Nations' Sustainable Development Goals by 2030 and the APEC Renewable Energy Doubling Goal.

作为世界上最大的发展中国家，发展依然是中国的第一要务，但鉴于能源资源与环境的双重压力，中国发展必须遵从低能耗强度与总量控制的原则。基于此，凸显了在中国开展终端用能能效提升、发展区域能源的意义与必要性--在供应侧，实现多种能源(形式与品位)的优化集成;在需求侧，降低用能需求、实现品位对应、温度对口、梯级利用、多能互补。合理降低对能源的品位要求，最大限度地利用

可再生能源和各种低品位能源，转变用能方式、提升能源利用效率。当前，能源科技创新加速推进，新一轮能源技术变革蓬勃兴起，以智能化为特征的能源生产消费新模式开始涌现。智能电网加速发展，分布式智能供能系统在工业园区、城镇社区、公用建筑和私人住宅开始应用，新能源汽车产业化进程加快，越来越多的用能主体参与能源生产和市场交易，基于智慧用能终端、多种能源互补的智慧能源

新业态初现雏形，成为推动分布式可再生能源规模化的重要途径。中国是世界第一大能源生产和消费国，也是第一大新能源生产和消费国。2017年党的十九大提出建设清洁低碳、安全高效的能源体系目标，中国的能源发展进入从总量扩张向提质增效转变的新阶段。2030年碳排放达峰的目标，2060年实现碳中和的愿景，中国已经开展了大量的终端能效提升、分布式能源应用实践，这些项目的推广，对于中国乃至世界都有重要意义。

中国或者说全球，目前正进入大变局的时代，能源转型之路依然艰巨，近一步降低化石能源比例、提高能源系统效率以及为用户提供可靠和可负担的能源等重要问题仍待解决。为此，开展智慧终端能源、分布式能源耦合的研究尤为重要。

课题通过分析中国及世界范围内终端能源利用现状、发展趋势、典型案例，结合对应的分布式能源关键技术及创新实践案例分析，如从城市层面开展可再生能源利用图则研究，编制建筑能耗标准，建立建筑用能管理平台等，可为中国清洁低碳、安全高效的现代能源体系构建提供支撑，也将为2030年联合国可持续发展目标和APEC可再生能源翻番目标的实现展提供新思想、示范新模式。
