Sorry to break it to you, but that's horrible. That's like saying car energy is the energy of a car. Potential energy covers everything from electrical to gravitational potential energy, light (or photons) have energy due to their motion (what you defined as kinetic energy), elastic energy is just another form of potential energy, magnetic too. Again, nuclear potential energy is, err, another form of potential energy.
tl;dr not the best way to define energy, actually pretty much not a decent way at all.
tl;dr^2: everything is pretty much potential energy, kinetic energy or a combination of the two.
