Read your book, and you will get the answer. :))
Bye now.
Kinetic energy is the energy in a mass of matter that is in motion, the energy of motion. Potential energy (where mass is in a gravity field) can be converted into kinetic energy Chemical energy (of an explosion) can be converted into kinetic energy Electrical energy can be converted into kinetic energy (eg in an electric motor)
Dynamos and turbines. For example: a windmill converts the kinetic energy of the wind into electric energy.
Kinetic energy is converted into electrical energy.
Water is stored behind a dam and possesses potential energy. When it is released and made to run down conduits down the dam to turn turbines the potential energy is converted to kinetic energy which in turn is converted to electrical energy.
Nuclear energy transforms to thermal energy (through nuclear fission or nuclear fusion). Thermal energy transforms into kinetic energy (eg produces steam that drives steam turbines). The kinetic energy transforms into electric energy (through electric generators).
generator
The potential energy of the falling down water transfers to kinetic energy. The kinetic energy turns turbines that are connected to electric generators where the kinetic energy transfers into electric energy.

You are transferring the heat into the water and changing it into steam. Steam has potential energy that can be released by cooling and expansion. This potential energy is released either in heat or can be converted back to kinetic energy by its expansion. This is how power plants work. Some fuel is burned to heat water to steam. Which contains potential energy converted from the heat of the burning fuel. This potential energy releases heat and kinetic energy as it is allowed to expand pushing and driving the turbines that turn the electric generators, and thus the kinetic energy is, by way of the generator converted to electric energy.
Hydro-electric powerplant
It converts mechanical energy into electric energy.
The kinetic energy of the wind (moving mass of air) is (usually) converted into electric energy.
The propellors are attached to a shaft that turns a gearbox that turns an electric motor that produces electricity. You need to study how an electric motor generator works. A regular electric motor turns when electric current is run through it. There are coils of wire wound a rotating armature that is placed between Magnets. An electric generator is made very similar. When the wire coils are rotated within the magnetic field, this produces electricity.
Water is stored behind a dam and possesses potential energy. When it is released and made to run down conduits down the dam to turn turbines the potential energy is converted to kinetic energy which in turn is converted to electrical energy.
