The Kardashev scale is a way of measuring a hypothetical civilization's ability to harness energy.
This scale has always made me think about the movie Independence Day (1996), my favorite example of a villainous alien civilization. Dr. Okun claims their technology is far more advanced than ours, and the evidence bears that out. From what I can tell, the aliens own significant advances in weaponry and transportation, to name just a few areas (yet were somehow completely undone by a few lines of code and a lowly nuke? But I digress...)
Anyways, given what we know about this species and their technology, is there in-universe evidence to suggest if this species might be categorized as Type II or Type III (or higher?) on the Kardashev scale?
