This book contains the proceedings of the 10th International Conference on Energy Engineering and Environmental Engineering (ICEEEE2023) that was held on August 6-8 2023 in Singapore. ICEEEE2023 is organized by Beijing Jiaotong University and Newcastle University. This book provides an international forum for discussion and communication of energy and environmental engineering. It is expected to report the latest technological developments in the fields developed by academic researchers and industrial practitioners, with a focus on renewable energy technologies and systems, energy efficiency and conservation, environmental pollution and control, sustainable development, and green cities. The contents of this proceedings will be useful to researchers, professionals, and policymakers alike.

This is the 9th edition of the International Conference on Energy and Environment Research, ICEER 2022, took place in the middle of September, ISEP, Porto, Portugal (Hybrid). This book includes all the well-presented papers in ICEER 2022. The maturity of this conference series has now been reached, with a large number of participants from academia, as well as a few coming from the professional field. Linking together energy and environment research is not an easy task. However, it is now understood that these fields are interconnected and that the answer to the challenge of a sustainable future depends enormously on the willingness and capability of problem thinking in an integrated manner. This book presents the participants in ICEER 2022 contribution toward sustainability, through energy and environment research, thanks for all.
