Build Ancient Refinery. 2 Ancient Refineries can support your golden throne. But I still hope they implement ascension events for luminary ASAP, Synth with life support system so stupid.
A synth luminary should be sustained by a comparable chunk of energy, enough to run whatever mainframe he ascends to in order to store his 9001 iq planet brain. Meanwhile the chosen one luminary could feed on zro (which should be able to be generated in-house by sacrificing psychic pops, but that's another issue) while the cyborg luminary might need a steady supply of technology devoted to keeping his hardware, wetware, and software all updated and working in synch. The geneticist luminary probably just needs a ton of food (or minerals) to keep his army of backup clones fresh and ready.
In all cases you'd want to balance these costs against the rarity of the resource, so while the chosen one needs zro to stay alive, he needs MUCH less than the synth/genetic luminaries do of their basic resources upkeep cost, while the cyborg's research-based cost would be somewhere in between.
