When an electric utility company "sells electricity", what is it that they actually sell?  Electricity is described as electrons in school text books.  Who is the owner of electrons?  Are electrons owned or are they independent of ownership?  Are humans able to see electrons?  No.  How can a human own something that he can not see?  If you went to a human court in an effort to prove ownership of some electrons, the court probably would want to see what you were talking about.  Can you claim to own the electrons that are part of a car that you own?  If you can not see those electrons, the answer probably is no.  If electrons are not owned by the electric utility company, how can they legally sell to you electrons (electricity) if they do not own those electrons (electricity)?

What an electric utility company actual sells is the force applied to electrons in a wire -- the force called voltage.  This pushing force against the electrons in a wire is what is changed to rotational force by an electric motor.  This pushing force against the electrons in a wire is what is used to create light -- when this pushing force pushes electrons through a small metal wire that has resistance to the flow of electrons.  This pushing force against the electrons in a wire is used to create heat in an electric heater or electric stove -- when this pushing force pushes electrons through metal wires or metal rods that have resistance to the flow of electrons.
