Entropy.
In any energy transformation energy is preserved.
The law of conservation of energy states: "Energy can neither be created or destroyed, only changed in form." Energy transformation is changing it's form. Note: This law only holds in Newtonian physics. I Einsteinian physics is isn't valid.
Because of the Law of Conservation of Energy, when you transform energy, any amount of energy that gets lost as one type of energy must needs appear - in the same amount - as another type of energy.
I am not entirely sure what you mean by "reversible by itself".An energy transformation is usually NOT entirely reversible. Some energy is wasted in the transformation, and (even though the energy is definitely still somewhere), you may need ADDITIONAL energy to transform it back.
The second law of thermodynamics states that energy cannot be changed from one form to another without the loss of usable energy. Enargy is usually lost in the form of heat. This law essentially means that energy changing forms is never 100% efficient.
energy transformation is the process of changing any kind of energy into another.

They should not, but in real life conductors transform some energy and this is called "loss". E.g., electric wire heats up when the current runs through it, a little bit of electricity is lost (due to wire's resistance) in form of heat. Transformation of energy should be kept as low as possible since any transformation in a conductor is unwanted.

Any kind of energy can be released depending on the circumstances.
