This question already has an answer here:

Is there any way to calculate how much anti-matter or dilithium I'll need to travel 5 light years at warp 4 (a general equation would be great, but if not the a ballpark estimate)?

If different engines from different generations have different fuel efficiency, I'd be open to whichever is most convenient to calculate, though it would also be nice to know how this has changed over the generations.

  • In which series? There's a big difference between Star Trek and TNG – Valorum Feb 21 '16 at 7:58

    This is not a duplicate - it is asking how much fuel is needed for the trip (as well as speed). – HorusKol Feb 21 '16 at 13:34
  • @Richard If I have to choose I'd say Star Trek: Enterprise, but I'll take what you can give me. Would also be interesting to know how fuel economy has improved over the years. – Hack-R Feb 21 '16 at 20:29
  • @Hack-R - That makes the question very much wider and less answerable. – Valorum Feb 21 '16 at 20:30
  • @Richard I'll take whatever you can give me... let's say TNG? If you have an answer for one series but not the other the question can be made specific to that series. – Hack-R Feb 21 '16 at 20:31
