The creation of energy, varies place to place, acid to base. Energy does not require oxygen per se, hence why stabilisation into evolution easier for any nanofauna in the modern day. Yet once anything conscious, that is, gaining energy within the bounds of environmental constraints. See more complex environments also a mamalian vessel. Yet a virus is not energy, yet a virus can be evolved by energy. However the term energy, gets thrown around as a specific jargon between academic and professional subcultures with a different meaning everytime.
The nano scale, that joyful realm.
You think of a coil of energy, say alkyls with the conscious ability to seek the elements that maintain the energy within an environment.
Could also think of the Caenorhabditis elegans

…the Riftia pachyptila

Then there is the Magnaporthe grisea

Also energies, different exchanges different roles.
Alas, elements pertain to habitat, and an over focus on such things keeps one eye blind to the environmental evolutions that can also occur.
As sometimes a pathogen is just a new direction of energy, sometimes a parasite protects its habitat, sometimes radiation creates a new food source and mode of evolution, almost always we can never explain the many complexities and layers to even just what exists habitually as life.
And Globins not evolved beyond the Metazoa make us goblins.
