With the success of the previous six years, ICGEA came to its 7th edition in 2023. It is proud to announce that 2023 The 7th International Conference on Green Energy and Applications will be held during March 10-12, 2023, in Singapore, sponsored by the Singapore Institute of Electronics and co-sponsored by Taiyuan University of Technology, China. The theme of ICGEA 2023 is to bridge and connect presenters and audiences with different disciplines and backgrounds and from other geographical locations. The most exciting and disruptive technology often happens at the edges and boundaries of various fields. So the conference aims to bring these brains together to synthesize ideas and knowledge from other sources to achieve energy innovation.
