The circulation of substance in a nature occurs by a unique way: the composite substance is formed of elementary particles, and which in term are made by disintegration of substance. Thus the energy changes from one form to another: kinetic energy of elementary particles, at formation of substance changes to potential energy of their connection at disintegration of substance. Kinetic energy can turn to thermal and other forms – mechanical, electrical... As we can see, the first cause of energy is complete or partial disintegration of substance. All other possible cases of energy generation are secondary and in its basis have the disintegration of substance. For example, the exothermic reaction. Heat of reaction is traditionally considered as a natural property. But, as it was stated on an example of burning reaction, the source of energy are the fast elementary particles electrino, pulled out by electron from the atom of the substance. The reactions of synthesis of molecules from atoms gives energy too. But this energy belongs to those particles electrino, which could interact with free electrons, that becoming the connection electrons. That is at synthesis the energy is a consequence of partial disintegration of substance too. The energy of synthesis is 1020 less than energy of complete disintegration to elementary
Thus, the essence and first cause of energy is a disintegration of substance.
Any substances can be split to elementary particles, and we can get energy from substances as from accumulators of energy. All substances by the amount of elementary particles – electrino and mass as a whole are in balance with external electromagnetic influence. On the Earth, first of all, it is the magnetic field of the Earth. At a deviation (surplus or deficiency – the defect) weight of substance in conditions of influence, including – partial disintegration with energy generation – is restored naturally. So, there is no need to take all at once from nature, – it is necessary to be content with those its mercies, which it gives without damage to ecology. Sparing partial disintegration of substance with preservation of its chemical properties of elements is that very legal necessary and sufficient limit, in particular, for energy generation, that the nature mercifully allows us to use. And, at last, for energy production we should apply the most widespread and accessible everywhere substances: air and water.
That is why such kind power based on partial disintegration of natural substances, defect of mass of which is restored by a nature in natural conditions, is called the natural power.
Nowadays there is no really other power, which to such extend satisfies all requirements of ecology and economy, except for the natural power. It also gives the basis to speak about natural power as a strategic (main) direction of solving the fuel problem on the Earth.
