If you're building near the surface, it's fairly easy to create enough solar panels to run them indefinitely. You can also of course, extend your base skyward with vertical connectors until you can put a tube section just below the surface. However, if you build at any significant depth, you're going to need to make sure you can power these reliably, preferably with thermal energy. Bioreactors are positively whimpy and require an annoying amount of upkeep. Nuclear reactors require a substantial amount of resources and still require occasional upkeep even if you have the wherewithal to pre-produce surplus energy rods.
