Electricity is a type of energy that consists of the movement of electrons between two points when there is a potential difference between them, making it possible to generate what is known as an electric current.  
Let’s see a practical example to understand it better. What happens when we turn on the light switch? The electrical circuit is closed, connecting the first point to the second. The electrons start to move through the metallic copper wire (the conductive element), and we immediately have light. The circulation of electrons through the conductor wire is transformed into electric light.
 Electricity is practically essential in our day-to-day lives 
 Accessible and easy to produce
Electricity can be generated from a wide variety of energy sources, both renewable and non-renewable.
Manageable and easy to transport
Electricity can be transported over long distances and on a large scale through transmission and distribution networks. 
Versatile and easy to transform
Electricity can also be transformed into other types of energy such as light (lighting a light bulb), heat (lighting an electric radiator), or motion (using an engine).
