If we are talking about waves through a medium like air or water it is the volume of the waveform which is directly linked to the energy it carries.
If you think about it the volume of the wave contains actual molecules (air or water or whatever) which have to be physically moved and this requires energy.
So if you use a 2D representation (think drawing of a sine for example) it is the area covered by that waveform which represents the energy of it.
Electromagnetic waves are in the subatomic region so there are no actual molecules or atoms (ie nothing with a real physical weight) which move. Completely different ballgame as only a (nearly) massless particle like a photon or electron moves through otherwise empty space.
