Trends of Telecommunications Energy Technology to meet Decarbonization Needs

Telecommunications energy technology has been developed with the focus on maintaining high capacity and high efficiency while giving top priority to maintaining the reliability of telecommunication services. Meanwhile, waves of decarbonization are spreading to solve the global warming problem. In this paper, we will discuss the trends surrounding such telecommunications energy technology from some viewpoints, such as the transition of technology of large capacity and high efficiency, the approach toward realization of decarbonized society, and the necessity of VPP (Virtual Power Plant) with ICT energy technology. Combining with ICT / IoT (Internet of Things) technology, telecommunications energy technology is changing its direction from technology to ensure the reliability of telecommunication services as a social infrastructure to fundamental one that contribute to the stable supply of electricity in decarbonizing society.
