Between steps 4 and 5, the mechanical energy of the turbine is converted to electrical energy.

Explanation:

A turbine can be described as rotating device which converts energy from fluid like water or energy from the wind into useful form of energy like electricity.

There are different types of turbines each made to generate energy from different sources.

To generate hydroelectricity, the water which is stored in a dam (potential energy) is released over a rotating turbine (mechanical energy) made of blades which converts it into electrical energy.
