In high school I learned that gas for coal, wind for wind mill, and tide for water, cause a turbine to spin and that powers an electrical generator and then boom we have electricity. What I want to know is how does the generator convert the kinetic energy of the turbine into electrical energy.

If you rotate a magnet around a wire, the pull of the magnetic field tugs on the wire and creates an electric current in it. (This doesn’t violate conservation of energy, because pulling the electrons in the wire also creates drag on the movement of the magnet.) Fundamentally, a turbine is just a device that uses fluid flow as the source of the magnet’s motion in order to take advantage of this effect.
