It’s already kinetic energy, as the vanes are moving.
If you are asking how you turn electric energy from a wind turbine back into mechanical (kinetic) energy, the answer is with an electric motor.
Do you mean electrical energy? Wind energy is already kinetic…so I will assume you mean electrical energy.
By using a phenomenon called magnetic induction. This is used in all electric motors, fans, alternators, etc. basically anything that involves rotating parts and electricity uses magnetic induction.
what happens is, if you have a coil of wire and a magnet, and you rotate the coil around the magnet (picture the magnet as someone’s head and the coil as a spinning halo), the moving magnetic field will cause current to flow in the wire.
it also works the opposite way: if you have a wire with current running through it, and you have a magnet near it, the flowing current in the wire will create a force which moves the magnet.
So a wind turbine uses wind energy to rotate magnets inside (or around) a wire coil, and the electrical current from the coil can be used to charge a battery, run appliances, etc.
For more information, just google "magnetic induction" and you will find articles with diagrams.
