A relatively stable molecular structure is not energy, but it has energy, so it doesn't need heat to calculate.

Not now, maybe in the future. Because according to Einstein's theory of relativity, matter actually has static energy (this energy can be calculated by E = MC 2), which is different from other so-called chemical energy, and its relative stability is generally unchanged. It doesn't work. It is this part of energy that is used by nuclear power plants, that is, the formula principle of those nuclear reactions is actually to convert the mass lost by atoms into energy. Under the current technical conditions, this kind of energy is not easy to use, but maybe in the future,

An enterprise consumes oxygen and argon in production, but the country has not included them in energy consumption and converted them into standard coal.
