Electrons are a significant part of every atom. Electrons are everywhere in the environment. When electrons are flowing through a conductor is results in the generation of electricity. So, to generate electricity, all you need is a metal wire which is a conductor and a Catalyst or means to start the electrons flowing.
Suppose, you are generating electricity by moving a magnet around a conductor, when the magnetic field is in motion relative to a copper wire, it will trigger the flow of electrons in the wire which will create electricity. In power plants, electricity is created by using large quantities of copper wiring wrapped around a shaft which is called an armature. The armature spins inside very large magnets at very high speeds.
