The conservation of energy is a powerful idea my good little dawg man. Here is the deal. Chemical bonds contain an enormous amount of energy. In fact the atom itself is held together by very powerful forces... thus breaking the atom, the atomic bomb, was quite a display. The bonding energy between the protons and neutrons of the atom is massive, getting it to come apart and to convert it into other forms of energy, heat, sound, and various forms of radiation, is a task we have sadly mastered. So quite simply, when the universe first cooled enough for atoms to actually be formed, that energy was trapped. We found a way to release it. The energy was already there when the universe first formec.
Now in explosives what you are basically doing is breaking chemical bonds that in most cases already exist. The energy is already there. All one is doing is taking chemical bond energy, and making it easier to turn into an enormous amount of heat energy very rapidly by tweaking a few bonds here and there and that does not require much energy. Kinda like pushing a big boulder on a frictionless surface 1 mm closer to the edge of a cliff. The heat energy released in the structure you found turns into gaseous products very rapidly which must expand. That my doggie lover, is an explosion. Wrap some tightly bound metal around this compound (that turns to gas very readily creating enormous pressures) any you got fragments of the metal shearing into millions of pieces and you tear a lot of people to shreds. Quite a horrible thing.

(CH2)6N4 + 4HNO3 → (CH2-N-NO2)3 + 3HCHO + NH4+ + NO3-

The reaction above taken from your site, is just the sythesis of said explosive. The first compound right after the--->

This reaction looks to me to be exergonic on its own. So you actually use no energy making the stuff, you give it off. So just making the stuff that is the explosive requires no energy at all, if fact it gives off energy. Thanks for the information.
