It is the transfer of mechanical/physical energy to electrical energy. The flowing water rotates a turbine which is attached to a generator and in turn creates an AC field.
The water's potential energy is converted into mechanical energy (movement); this is then converted to electricity.
No
kinetic energy (potential energy) which transfers to mechanical energy
Coal fired
In hydroelectric power station we use the potential energy of water to generate electricity.

It takes energy to generate electricity. Mechanical energy or thermal energy or nuclear energy , chemical energy,etc, etc,etc
We generate electricity from other forms of energy. Such as wind, sun, ect...
use electricity generators which generate electricity from candle energy
let the geothernal energy to boil the water, then use the stream to generate the electricity. it is the same way when you use coal generate the electricity. but the detail system is very complicated.
Mechanical energy
potential energy
