Hi Mission,
It sounds like you're trying to form a mental picture of "pure energy". One simple way to think about energy is to divide it into two types. One type would be kinetic energy, like the energy in a baseball thrown by a pitcher. This is the energy of motion.
The other type is, as you correctly surmised, the pure energy you're looking for, though pure energy isn't really a scientific term. It is the energy of electromagnetic radiation, radio waves and light and so forth. Electomagnetic radiation consists of photons, and I suppose it would be okay to think of them as "pure energy", because they are energy unencumbered by matter.
But "pure energy" isn't really a scientific term. I would suggest thinking about kinetic energy on the one hand, which is just matter in motion (the kinetic energy of an object moving at non-relativistic speeds is Ek=mv2/2, where m is mass and v is velocity), and about electromagnetic energy on the other, the energy of photons (the energy of a photon is Ep=hf, where h is Planck's constant and f is frequency).
