The only kind of energy that dark matter is -- well, MATTER. Or mass, if you prefer, which is the same thing. We don't know what KIND of matter this stuff is, hence the name "dark." The only two things we know about dark matter is that (1) it interacts with baryonic matter via gravity but (2) it does NOT interact with baryonic matter via the electromagnetic force or the strong force. At this point, we're still working on what type of matter would do that.

Sound is a form of energy that is produced when objects vibrate and create compression waves through a medium like air. Sound energy can be heard and has the ability to travel through different mediums, but it is not considered matter itself.
Sound.
For example thermal energy.
it has kinetic energy = 1/2 mass x velocity squared
During burning, one kind of matter turns into its ash, gases, and heat energy. The chemical bonds in the matter are broken, releasing energy in the form of heat and light, and leaving behind the remains in the form of ash.
Thermal energy is the form of energy that measures temperature. It is the energy that comes from the motion of particles in matter, which determines the temperature of an object or substance.
Because energy can't be created (or destroyed, for that matter); it can only be transformed from one form into another. Note that we're taking the relativistic definition of "energy" here in which matter is really a kind of frozen energy.
It is not a matter. It is one of seven kind of energy. Electricity is produce generator.
I think the question is a bit mixed up, but I think this is the answer. Scientists talk about "mass-energy" as a unified thing. Just after the Big Bang "energy", in the form of radiation energy, was dominant. However, today it seems that "mass" is the dominant form. In other words, "matter" now dominates the Universe. There is the complication of "Dark Matter" and "Dark Energy". Cosmologists still don't really know what these are. So that puts some uncertainty into this discussion of matter and energy. Some scientists believe that it is now "energy" that dominates, because of the discovery of Dark Energy. (Also, cosmologists think that both "matter" and "anti-matter" were created, but that there was a slight imbalance in favour of matter and the anti-matter seems to have been destroyed, leaving just "matter".)
None of these. It is energy. It is not matter. But according to the law of relativity, energy can be converted into matter.
