Detailed Solution

The correct order of the energy conversion in a hydroelectric power plant: From water to turbine to the generator is given by kinetic energy to mechanical energy to electrical energy.
Hydropower plants can be divided into three parts,

Dam: It is used to store water. Since stored water has potential energy, it can be said that initially, the energy is stored in the dam.

Turbine: The stored water in the dam is made into the turbine. Since the falling water has kinetic energy, the turbine converts kinetic energy into mechanical energy.

The generator does the third and last work. The generator generates electrical energy with mechanical energy. And now this electrical energy produced is supplied to our home.

In a hydroelectric plant, water falls from a sufficient height to generate kinetic energy. This kinetic energy runs the turbine and gets changed into mechanical energy. The turbine transfers this mechanical energy to an electricity generator which converts the mechanical energy into electrical energy.
Energy conversion takes place in a hydropower plant:
Potential energy ⇒ kinetic energy ⇒ mechanical energy ⇒ electrical energy
