Modules are items used to enhance existing buildings' capabilities. They are expensive, require appropriate research and are produced slowly, but can eventually greatly improve the efficiency of a factory.

Assembling machine 2 can hold 2 modules, Assembling machine 4 can hold 4, [[Lab]] 2, [[Basic beacon]] 2, [[furnace#Electric furnace|Electric furnace]] 2 and [[Electric mining drill]] 3.

:If you want more products per second, use a speed module.
:If you want more products per input resource, use a production module.
:If you want more products per watt of energy, use an efficiency module.

=== Speed Module ===
Used in many [[Modular armor]] recipes.
* Level 1: Speed bonus: +20%, [[Energy]] consumption +50%
* Level 2: Speed bonus: +30%, Energy consumption +60%
* Level 3: Speed bonus: +50%, Energy consumption +70%

=== Productivity Module ===
Productivity modules add a second "production bar" at item producing buildings and labs. It fills at the speed of (production - 100%). When it reaches 100%, an extra item (or items, in recipes that result in more than one) is produced.
* Level 1: Productivity: +3%, Energy consumption +50%, [[Pollution]] multiplier +30%
* Level 2: Productivity: +6%, Energy consumption +70%, Pollution multiplier +40%
* Level 3: Productivity: +10%, Energy consumption +90%, Pollution multiplier +50%

=== Effectivity Module ===
Minimal energy usage is 20% of base energy usage.
* Level 1: Energy consumption -30%
* Level 2: Energy consumption -40%
* Level 3: Energy consumption -50%

== Examples of usage ==
At 100% productivity (no modules), producing a single level 3 module costs 1472.5 [[Copper plate]]s, 775 [[Iron-plate]]s and an [[Alien artifact]].
At 160% productivity (maximal achievable without [[Beacon]]s) at every [[Assembling machine]] used in the chain, the cost decreases to much more manageable 123 copper, 95 iron and 0.625 of an alien artifact.

[[Electric furnace]]s are huge power hogs at 180 W per furnace. 2 basic effectivity modules reduce it to 36 W - almost 2.5 [[Solar panel]]s worth of power. At 140% productivity (in every assembling machine), 2 modules cost 10 iron and 28 copper, while 2 solar panels cost 45 iron and 24 copper.

[[Electric mining drill]]s create 9 units of [[Pollution]] with no effectivity modules and 1.8 with 2 basic ones.

Same [[Electric mining drill]] with 3 Productivity modules 3 would create 83.25 units of [[Pollution]].

Tralala:

Furnaces are used to smelt [[items#resources|resources]] into usable [[items#Intermediate products|products]] for further usage. This makes them a key building for development and automation. Starting with very basic [[Stone_furnace|stone furnaces]] the player can advance through [[research]] and replace them with more efficient and faster furnaces later in the game.

Furnaces can be affected by [[Beacon]]s.
