Why is Hydro-Electric power so important in NZ

Hydro-Electric power is really important for NZ. Because in NZ we have a growing countries and we have a lot of extra water that we were not using so somebody made a dam witch uses water as power. It powers a tonne load of houses and powers buildings and lots of other stuff. It costs money but it stops flooding, Dams are already being built, It has sustainable power, Water is natural and it just comes by its self.
