Some teachers will say that electricity is kinetic energy because it involves moving electrons. The problem with this is that the electrons' kinetic energy is not what provides energy to the light bulb or device. This is apparent when you consider that the electric current going into, say, the light bulb filament, is the same as the current going out of it. So that's not what's supplying the energy. The energy actually gets transferred by the electromagnetic field SURROUNDING the wires, not by the electrons IN the wires. So it's really misleading to say that electricity is a form of kinetic energy.
