Energy density - Wikipedia

In physics, energy density is the amount of energy stored in a given system or region of space per unit volume.It may also be used for energy per unit mass, though a more accurate term for this is specific energy (or gravimetric energy density).. Often only the useful or extractable energy is measured, which is to say that inaccessible energy (such as rest mass energy) is ignored.
