I didn't know that there ware some schools which have its own wind turbine. What a good idea it is to save money by using wind power to make energy! It is good for school, and good for environment, too. Also, it is a good business for them to sell extra energy.I heard that Japan is rich in geothermic, so maybe we should use it wisely.

Spirit Lake have built two wind turbines.Otherhands in Ohyu, it has solar panels on the roof. Natural power is very important.
