	Filling devices with '''productivity modules''' is recommended when resources are scarce. An example would be more advanced products not being produced enough due to bottlenecks. It will take longer and more energy, but the overall amount of products per time will be higher. Productivity is especially useful in recipes that consume a lot of resources per second such as [[electronic circuit]]s, as this will result in a lot of free items being created and quickly cover the cost of the module. Also by saving the need to mine ore, smelt plates and process intermediates for those free items the additional energy cost can be easily covered.

Modules are also able to control [[pollution]], as '''pollution depends also on [[Electric system\|energy]] usage'''. So reducing a machine's energy usage by 40% with a efficiency module 2 will also reduce its pollution by 40%. Beware as this also works vice versa! Also note that if you're using productivity modules, a speed module can sometimes provide better efficiency gains due to the fact that the machine will now be producing much more items per second. Efficiency modules also generally don't work well in beacons.		Filling devices with '''efficiency modules''' is recommended for electric furnaces as these use a lot of power.

	5% productivity means that 5% more outputs are generated over a given space of time. So if a machine would have output 100 products in a given time, it outputs 105. A 5% speed penalty means the machine operates 5% slower. If a machine would have output 105 products in a given time, it only outputs 95% of that, which is not 100; it is 99.75.		5% productivity means that 5% more outputs are generated over a given space of time.

	[[Productivity module]] 1s have a 6% speed penalty. The minimum productivity bonus needed to overcome this speed penalty is 6.3%, which requires ~~an epic~~ prod 1 (though ~~rare~~ comes close). To offset the 10% speed penalty from a [[productivity module 2]], you need a productivity of at least 11.1%, which requires an legendary prod 2 (though epic comes very close). To offset the 15% speed penalty from a [[productivity module 3]], you need productivity of at least 17.6%, which requires an epic prod 3 (though rare comes very close).

	'''Quality modules''' have unusual scaling for their quality bonuses due to how strong [[quality module 2]]s are. A rare quality module 2 has the same bonus as an uncommon [[quality module 3]].

	There are three types of modules in ''Factorio'', each with 3 tiers of effect. Higher tiers have stronger effects but are more expensive.

	As a rule, the effects of multiple modules are '''additive, not multiplicative''', meaning they don't have diminishing returns (except that consumption is capped to -80%), so if an assembler is making 2 items per second, adding one speed module 3 (+50% speed) will increase item production by 1/s, and a second speed module 3 will increase production by another 1/s. Consumption modifiers work the same way, for example if a machine is consuming 180kW, the first efficiency module 1 will reduce energy use by 54kW, the second will also reduce energy use by 54kW. There is no difference between putting two speed module 1's in one machine and two efficiency module 1's in a second machine, compared to putting one of each in both machines - in both cases the total items produced per second and average energy required per item is identical.

Efficiency modules also generally don't work well in beacons.

	When using unclean energy sources, such as boilers in the early game, it is recommended to use efficiency modules exclusively in all machines, with the exception of labs which should use productivity modules. This is because the additional pollution created by the production of electricity will always result in a net loss when using other modules. Labs are able to overcome this limitation due to their naturally low power consumption, the fact they don't contribute any pollution directly, and most importantly because the productivity bonus applies to all science packs being researched, leading to savings of several MJ across the entirety of the production chain in exchange for only a MJ or two of additional expense (roughly 2.2MJ of additional expense for productivity 1, with that number decreasing with higher tiers)
