At Tamagawa, the Tamagawa Soft Energy Project (TSEP) has begun, undertaking energy studies aiming at zero emission. The focus of the studies has been on the efficient use of solar energy and wind power. In the Tamagawa Solar Challenge Project (TSCP), Upper Division (9-12th) and University students collaborate to compete in solar car races. The races serve as a testing ground for the efficient use of solar energy. Excellent results have already been attained. Meanwhile, Tamagawa Windmill Project (TWP) gives students the opportunity to think over wind power as a form of energy, through competitions involving the capacity and design of windmill. Windmills have gathered attention as a zero-emission energy source, along with solar energy. Pilot windmills on the campus have been used for surveys on annual wind volume and electricity generation, as well as for actual power generation and lighting. We look forward to the results likely to be achieved. In the windmill competition, large numbers of students respond each year to calls for unique windmills, from K-12 and the University. The Project aims not only at energy development but also at educational effects to encourage more students to think about energy and the environment. There is a plan to incorporate the Project into daily educational and research activities, to stimulate the entire school into thinking about energy. TSCP
