As shown by the source given in my answer to this question, power consumption is based on the amount of rooms. However, it doesn't go into detail... Now, thinking about possible layout strategies, I want to know:
Do elevators use power?
By "use", I primarily mean if they increase consumption of power. I recently restarted, so I am in no position to test this (it could be tested by looking at how fast power depletes before/after building a bunch of elevators).
Has anybody tested this?
