The wiki states that each zone requires 10 (:power) to operate.

1) I assume this also holds for the Power Zone itself, as it can house up to 1 billion ?
2) Quoted from the same page: "Additionally, every 0.1 billion people in the system require 1 power (so if the total population is 5 billion, they would require 50 power)." I assume 'orbit' is meant instead of 'system'?

Power is paid for population separately. A Power Zone does require power, like any other zone. You cannot generate power if you cannot see what you are doing because you do not have power to light the room.

Correct. This is now fixed on the Wiki.
