Yup... you pretty much need all your other buildings (except houses and the command center) to be in the power ring of a Power Core. I certainly make sure, not just carbon centers, but nova and ore centers, are getting power. I like to build lots of walls and towers, so I want the ore, and I want my workers upgraded to collect it quickly. 4 upgraded workers will do the job of 6 or 7 non-upgraded ones in the later ages, so you can use the left over population quota to build more troops, or to divert the workers to more rapidly building something like a Fortress or a Monument.
I try to power everything that needs power, but, I do give priority to Nurseries, Carbon Centers, and Unit-creation buildings like Troop Centers or Air Bases.
May the Force be with you.
