View source for Power

[[Power]] is a mechanic used by [[Habs]] to represent the necessary electrical power for operating the hab's modules. It can come from solar panels, fission reactors, or (after [[Deuterium-Tritium Fusion]] is researched) fusion reactors.

== Mechanics==
A hab may only ever have operate modules if it has enough power to run those modules. Otherwise, the modules are disabled. The player may choose to de-power modules manually (subject to the limits on prioritized modules, below), and to re-power modules that have been turned off if there is enough power. If there is not enough power to run everything, the game will shut down modules until the power balance is no longer negative. 

=== Prioritized Modules ===
To prevent players abusing the power system for advantage, certain modules cannot be de-activated manually. These are listed in the [[Hab Module List]] as "Cannot Depower". Those modules are: 
* Certain campaign modules: {{icon|protectorate}} [[Sentinel Complex]] and {{icon|exodus}} [[Deep Space Telescope]]
* Ship supply facilities: [[Supply Depot]], [[Space Dock]], [[Shipyard]], and [[Spaceworks]]
* Farms: [[Hydroponics Bay]], [[Farm]], and [[Agriculture Complex]]
* Defensive installations: [[Point Defense Array]], [[Layered Defense Array]], and [[Battlestations]]
* Marine barracks: [[Marine Platoon Barracks]], [[Marine Company Barracks]], and [[Marine Battalion Barracks]]
* [[Helium-3 Mine]]

=== Solar Power Mechanics ===
Solar panels are based on the real-world physics of solar energy, so their power generation increases and decreases at a rate that is proportional to the onverse square of the distance to the [[Sun]]. They are also limited by the shadows cast by the body they are on/orbiting, so ground habs will get the least solar power, and space habs will get more as the orbits get higher. 

Here is a selection of common hab locations, with their solar power production figures:

|}

For surface locations, power figures do not include any bonuses from solar mirrors. 

=== Solar Mirrors ===
Solar panels on ground habs may also be enhanced by use of solar mirrors on orbital habs. The maximum power that can be produced is 160 per [[Solar Collector]], 640 per [[Solar Array]], and 1920 per [[Solar Farm]], no matter how many mirrors are in use.

* Build cost scales with distance to the sun to model the fact that the mirrors need to be larger to collect the same amount of light. (Multiply all material costs by the distance in AU squared, so at Mars the multiplier is 2.3 and at Jupiter it's 27.)
