Energy Transfer, Storage And Conversion

[DendromutantX]

I'm curious how aliens turn energy they get from elirium into light, i mean you dont see any open wires in crushed UFOs, so its not electricity. Also, do they have any energy generators on the base, if yes, what it runs on? I mean I only seen elirium tanks on my own base in hangars, and aliens also need some kinds of utilities.
