After conducting preliminary research and internal discussions on its feasibility for three years, Chiba University of Commerce (CUC) officially started a project in 2017 to become a 100% RE university, aiming to produce more power than it consumes, and achieved this goal in 2019. Based on their direct involvement in the project, the authors describe the CUC case study to provide an example of a 100% RE project for other universities and businesses that wish to implement something similar.
