Module

Template:Technology 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, 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.

In addition to improving the efficiency of the factory, modules are also used in many late- and endgame recipes such as modular armor and its equipment.

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: + 4%, Energy consumption +40%, Speed -15%, Pollution multiplier +30%
• Level 2: Productivity: + 6%, Energy consumption +60%, Speed -15%, Pollution multiplier +40%
• Level 3: Productivity: +10%, Energy consumption +80%, Speed -15%, 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%

Stacking penalty

More modules of the same type in one device will give diminishing returns. Because of that, it is more effective to have a mix of modules in the devices, and get more bonuses over the crafting cascade (assembly lines).

Examples of usage

Electric furnaces are huge power hogs at 180 W per furnace. 2 basic effectivity modules reduce it to 36 W - almost 2.5 Solar panels worth of power.

Electric mining drills 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 76.5 units of Pollution.

Productivity

There where many discussions about the productivity. This post brings the problems of calculating the productivity to a point, where it becomes understandable.
