Power (Power (Civ4)) refers to electrical power, and its purpose is to augment the Factory with an additional +50% Hammer (Civ4). The existence of the asset in a city adds an unconditional unhealth penalty of +2 Unhealthiness (Civ4) irrespective of the source and whether the power is being put to use by this structure.

Power generated by a Dirty source (coal or shale) carries with it an extra +2 Unhealthiness (Civ4) penalty. Clean power sources, when available, take the place of dirty power and remove this additional burden.
