"Non-physical" energy doesn't exist.
All mass is energy. If the basic elements of consciousness have mass, which we can safely say because neurotransmitters exist, then consciousness is, like the res of the universe, physical energy.
Everything has energy, even pure vacuum.
The term "energy" more or less means the capacity to do physical work, i.e. by moving stuff. It is not appropriate in this sense. Neither is anything else, really, because this case is impossible.
The evidence for this comprises the various and sundry fields of neurobiology, biochem, biophyisics, and the like, which provide no evidence that anything going on inside the human head violates the laws of physics in any way.
Of course consciousness is made of "something", or, rather, several somethings, like muons, pions, electrons, etc. As to whether or not in can be located, I direct you to the clustermind**** that is the Copenhagen Interpretation.
I'm sure this should be obvious by now, but number 2 is the only scientifically valid answer.
Of course it matters; it is one of the most fundamental questions mankind is faced with.
