As we all know water energy is the energy that is taken from water. As such we all know energy cannot be created so where this energy comes from? Yes the gravitational force of the earth provides the water with energy. Water has energy within itself. It has two types of energy. Water has potential energy when it is stored and kinetic energy is used during motion. So the potential energy is unused so using this power is generated from water.Let’s check in detail. Water has potential energy when stored. So this potential energy is converted into kinetic energy when the water is made to fall or flow. So when the stored water from the reservoir flows’ through the dams it gets kinetic energy this is due to the action of the gravitational power of water. This kinetic energy gets converted into mechanical energy when this water strikes the turbine blades. The turbine spins and mechanical energy is created. This mechanical energy gets converted into electrical energy with the help of the generator and this power is carried to all places of need with the help of the power lines connected to them.
