- it is extracted through pipes that lead to a dam.
- it is stored by being put into a generator.
- it is used for lighting and other electrical everyday appliences and, is generated by the water pushing a turbine in the generator to gather kinetic electricity.
- the impacts of this is some fish can get stuck in the turbines and can die and pollution from the metal parts can ruin water sources.
