What is hydroelectric powerstation

It is a power station fueled by waiter it turns water power into electric energy which could then be used for any kind of energy then (simplified version ^)

A hydroelectric power station is a generating station that utilizes the gravitation force of water in high levels for the generation of electricity.

How it works: The kinetic energy in sources of flowing water (runoffs from springs and lakes, rivers, etc.), turns the blades in the turbines, generating mechanical energy. The turbines then turn a generating rotor which then converts the mechanical energy into electricity.
