The Extended Energy Big Data and Strategy Research Center (EEBD&SRC) is an innovation application, development and strategy research center for energy big data. The center aims at developing innovative theories, technology, platforms, and services based on extended energy big data (EEBD), so as to solve issues arising in the context of energy development. The center is committed to building an interconnected EEBD, with energy at its core, connecting data related to various aspects of reality (society, economy, environment, ecology, climate, market, engineering, science and technology, policy, etc.), while developing advanced technology to discover interrelations between these dimensions, and finally applying those findings and technologies to smart energy, smart management, and smart green and low carbon, so as to meet the needs of governments, enterprises, and industries. There are five groups within the center: The EEBD-based Smart System Group, EEBD-based Smart Energy Group, EEBD-based Smart Management Group, EEBD-based Smart Green and Low-carbon Development Group, and EEBD-based Data Technology Service Group. EEBD&SRC is committed to contributing to China’s ambitious goals of carbon peaking in 2030 and carbon neutrality in 2060. EEBD&SRC is one of the seven key R&D units supported by the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) and the Shandong Energy Institute (SEI). The center is led by a director, Prof. TIAN Yajun, and an honorary director, Prof. XIE Kechang, the former vice-president of the Chinese Academy of Engineering (CAE).
