Abstract
We study the nature and location of electromagetic energy for two cases. The energy density for electromagnetic radiation is shown to be , with the energy contained in the electromagnet fields. For a static charge distribution, the electromagnet energy is contained in the charge, with an energy density, , There is no energy outside the charge distribution. The electromagnetic fields do not contain the energy, and cannot be considered an energy density in this case. There is no ambiguity in either case as to where the energy is located.
