It is pleased to announce that 2027 The 9th International Conference on Clean Energy and Electrical Systems will be held in Osaka, Japan on April 28-30, 2027.  CEES covers a broad range of clean energy and electrical systems topics, and it will continue the tradition of the past editions organized in Vancouver, Nanjing, Tokyo, Kyoto, Sendai and Osaka. Clean energy, or green energy, refers to energy that does not emit pollutants and can be directly used in production and life. It includes nuclear energy and "renewable energy." With the continuous growth of energy demand and the increasing awareness of environmental protection in countries around the world, it is urgent and imperative to establish a clean energy innovation research and development, promotion and application system. Electricity will play a huge role in the development of clean energy. The future development trend of energy must be towards the direction of clean energy, and the ecological and economic benefits it brings will be immeasurable.

In the face of global challenges posed by climate change and the increasing demand for energy, the pursuit of sustainable and clean energy solutions has become more critical than ever. The 9th International Conference on Clean Energy and Electrical Systems will be centered around the theme of "Empowering a Sustainable Future," seeking to explore and promote cutting-edge research, transformative technologies, and forward-thinking policies that can drive the transition towards a cleaner and more sustainable energy ecosystem. On the basis of it, the goal of CEES 2027 is bridging and connecting – across disciplines, practices, places and understandings. The most interesting things happen at edges and boundaries, and so the aim of the conference is to demonstrate and examine different approaches in innovative power and energy technology solutions. It features invited speakers as well as peer-reviewed paper presentations. The conference is completely open (one needs to register first), you will not have to be an author or a discussant to attend.
