Chemical energy in the water becomes thermal energy as it moves through turbines, which change thermal energy into electricity.
Chemical energy in the water becomes thermal energy as it moves through turbines, which change thermal energy into electricity.

Kinetic energy in the water becomes potential energy as the water moves through turbines, where kinetic energy becomes mechanical energy that spins a generator.
Kinetic energy in the water becomes potential energy as the water moves through turbines, where kinetic energy becomes mechanical energy that spins a generator.

Potential energy in the water becomes kinetic energy as it moves through turbines, which turn kinetic energy into mechanical energy that spins a generator, which changes mechanical energy into electricity.
Potential energy in the water becomes kinetic energy as it moves through turbines, which turn kinetic energy into mechanical energy that spins a generator, which changes mechanical energy into electricity.

Mechanical energy in the water is transferred to turbines that spin a generator, which changes the mechanical energy into electricity.

The correct response is:

Potential energy in the water becomes kinetic energy as it moves through turbines, which turn kinetic energy into mechanical energy that spins a generator, which changes mechanical energy into electricity.

This accurately describes the process by which stored water (potential energy) flows down, converting to kinetic energy, and ultimately leading to the generation of electricity through the turbines and generator.
