Wind turbines

Last semester before we left from break we had our last project. That project was to make to make a wind turbine. first we had to  research windturbines and alternative energy. there was an article about how schools up north are using alot of money on heating. They were thinking about cutting field trips , school days and other stuff like that. So this is when the wind turbine comes in. A wind turbine uses wind energy  to make energy. when its turning it make a dc(direct current) and make Ac (alternative current)  which can powers a house. So in class we made paper replicas.  making them was very hard for me . after we made the we had tested them to see if we can power a light bulb.
