In the 21st century, it is required to build a sustainable and circulating society in which global environments such as food, water, air, forests and energy are secured. Especially in Japan, where energy resources are scarce, experts of the field of energy are needed. This course is aimed at fostering engineers capable of analyzing and solving energy related problems such as securing energy resources, improving energy conversion efficiency, and developing energy efficiency technologies. Courses covering 3 engineering fields - heat/fluid energy engineering, energy device system engineering, and architectural/environmental system engineering are provided with faculty from a variety of fields and business enterprise experience. Energy System Engineering is looking for passion of youth for the future.
