A revised version.  The main derivation is reorganized, some denotations are changed.

In the proposed theory for analyzing the electromagnetic radiation and electromagnetic mutual couplings in vacuum, the electromagnetic energy associated with a source is separated into three parts: a Coulomb-velocity energy, a radiative energy and a macroscopic Schott energy. At the instant that the sources disappear, the Coulomb-velocity energy disappers simultaneously; a short time later, the total macroscopic Schott energy becomes zero, while the radiative energy keeps propagating and the total radiative energy becomes constant. By applying the Lienard-Wiechert potentials to a moving charge, this paper illustrates that the macroscopic Schott energy is corresponding to the Schott energy in the charged particle theory.
