In Stellaris, an empire's economy is based around resources which are produced in limited quantities on astronomical objects and are used for various purposes.

Resources are obtained by having a pop on its tile in a colony or by building a specific type of station in space. They can also be produced on a planet by constructing buildings and these stack with already existing resources of the same type. Gathered resources can benefit a planet, a sector or an empire as a whole.

Resources can vary from fairly common Food.png food crops to very rare substances such as Dark Matter.png dark matter and from physical Minerals.png minerals to "produced" knowledge, such as Engineering Research engineering research.

In that way, resources are very important and ought to be quickly scouted, exploited, and developed.

There are three kinds of resources: Material, Abstract and Strategic.

Material Resources[edit]

Basic resources are the most important type as they provide the means to expand both geographically, developmentally and technologically. They are gathered and stockpiled on a monthly basis, but not necessarily on the same day. While they all have a stockpile, how that stockpile and the excess is used varies fundamentally between each resource.


Energy credits[edit]

Energy Credits.png Energy credits is an energy backed currency accepted by all space-faring races, and acts as the Galactic Market's currency and "food" for robotic pops.

They are mainly used for recurring expenses such as maintenance of buildings, ships, spaceport modules, stations and food replacement for Robots. There is a significant maintenance cost for colony ships and colonies that are being established. Energy credits are also expended as lump-sum payments for other various tasks, such as recruiting leaders, clearing tile blockers, initiating terraforming (a significant investment, with the cheapest process costing 2000 Energy Credits.png energy), and building robots.

Finally, they can also act as a bargaining chip in trade deals with early empires. However, as empires grow more established, producing and storing larger amounts of energy credits, they become less valuable for trade. However that can make it really cheap to acquire them via trade deals, especially for Minerals.

They can be acquired by building mining stations around celestial bodies with energy deposits, building trading post modules in a starbase and by constructing and upgrading power plants on colonized worlds. They are produced and stored on a sector-by-sector basis as well as empire basis so it is advisable to keep an eye on total energy balance before transferring systems to a sector.

It is very important to keep a positive balance as not having enough energy credits will cause a critical resource shortage that reduces the output of Minerals.png minerals, all research, ship and army build speeds, ship shields and weapons damage by half. Additionally, colonies in the process of establishing themselves on new worlds will halt their progress and the output of robotic pops will be reduced by half.

Generally, consistency of energy output is more important than the amount, unless active expansion is in process.

Empires can stockpile up to 5000 energy credits by default, with generating-related technologies and the Resource Silo starbase building increasing the limit. Sectors have their own separate stockpiles.


Minerals.png Minerals is a collective term for the basic resources an empire needs to construct stations and planetary buildings. They're also consumed by various jobs as materials.

They, like Energy Credits.png energy credits, can be obtained by building mining stations around celestial bodies with mineral deposits, building mines on habitats and by constructing and upgrading mines on the surface of planets and moons. They are also produced and accumulated on a sector-by-sector basis.

Empires can stockpile up to 5000 minerals by default, with mining-related technologies and the Resource Silo starbase building increasing the limit. Sectors have their own separate stockpiles.

The primary purpose of Minerals is as the raw material for Space and Planetary Construction. Significant lump sum expenses are applied to these projects upon queuing them up, which will then take some time to complete. Here it acts as the primary limiter on expansion and planet development.

Secondly, Minerals also act as a valuable commodity for trade deals, as they are consumed by a significantly wider range of projects than Energy Credits.png energy credits; there are few times where an otherwise somewhat unattractive trade deal cannot be made attractive to another empire by offering them a modest sum of minerals.

Finally, minerals are used to manufacture consumer goods and maintain ships. Both act as a small but persistent drain especially for large empires. See Consumer Goods and Ship designer for details.

It is often important to have a sizable storage, especially so in times of war, in order to better deal with urgent situations and be able to survive production sites being lost or cut off. Not having enough minerals will cause a critical resource shortage that reduces Mod ship armor mult.png ship armor, Mod army damage mult.png army damage, weapons damage and research speed by half. A careful player should decide how many months or years worth of minerals should be kept in storage as a reserve. Minerals production should be pretty much maximized at all times, unless there is energy shortage or the empire has passed the point of saturation and cannot put minerals to use faster.


Food.png Food represents the various nutrients requires to sustain and grow organic pops. Empire food rationing can be managed via the empire policies, evaluating food spending against pop growth and happiness.

Each planet grows its own Food.png food which is then added to an empire-wide stockpile that feeds the whole empire, with every planet exporting and importing food according to production and consumption. Surplus food not increases population growth directly, but 1000 Food.png food can be spend on planetary decision to boost local population growth by 25%. An empire-wide food shortage leads to starvation, which decreases happiness by 25% and pop growth by 75%, although existing pops will not die. Food is only used by organic pops; machine pops use Energy Credits as a replacement.

Food can be produced by constructing orbital hydroponic farms on starbases or by creating farming jobs via building farming districts and hydroponic farms and food processors on the surface. The baseline output of one farmer is +6 Food.png food, it can be boosted by productivity modifiers (stability, repeatable techs) and food processors.

An empire can also obtain food by extracting it from pops, which is done by either enslaving the species and setting the slavery policy to "Livestock" or by purging the species and setting the purge policy to "Forced Labor" or "Processing". Livestock yields 4 Food.png food per pop every month, although the pops in question will still consume 1 Food.png food per month. While Forced Labor and Processing purges yield 3 and 6 Food.png food per pop every month without any upkeep until the pops are killed.

Food is one of the cheapest market resources, rated at 1 Energy Credits.png Energy per unit without fees.


Consumer goods[edit]

Consumer goods.pngConsumer goods is an advanced resources that represents the various gadgets, luxuries and goods necessary to give your pops a good life and to perform intellectual jobs such as research. Only non-Gestalt consciousness.png Gestalt consciousness (except Civic machine servitor.png Rogue Servitor) empires have access to Consumer Goods.

The base amount of goods a pop requires per month depends entirely on the living standards set for that particular species. Each unit of Consumer Goods has a base cost of 0.75 Minerals.png Minerals.

Robots and Droids do not need consumer goods while Synthetics' consumer goods consumption depends on AI Rights Policy.

The base costs are affected by various modifiers to calculate the total amount of minerals necessary to produce enough consumer goods to fulfill the needs of the population. These modifiers depend on factors such as ethics, traits, planet modifiers and whether the empire is engaged in a defensive war. Regardless of what sum present modifiers give, the lowest possible consumer goods cost that an empire can have is capped at Mod pop consumer goods mult.png –90% Consumer Goods Cost.


Alloys.pngAlloys are advanced resources with a military application, which an empire need to construct Ships and Starbases.

Trade Value[edit]

Trade value.pngTrade Value represents Civilian day-to-day economic activity. Only non-Gestalt consciousness.png Gestalt consciousness empires have access to Trade Value.

Starbase collect Trade value.pngTrade Value and convert it into other resources such as Energy Credits.png Energy credits if connected to your capital planet through a Trade Route. Trade value.pngTrade value that is collected by your capital Starbase does not need a Trade Route to generate Resources.

Abstract Resources[edit]


Influence.png Influence represents the political and diplomatic clout of the empire's leaders (or the processing power of Gestalt consciousness.png Gestalt Consciousness's nexus or core AI), and acts as a limiter of an empire's internal and external affairs. It is used for constructing starbases to claim ownership of new systems, claim other empire's systems, enacting most edicts, incorporating vassals, changing and reforming government types, building some empire-unique buildings, maintaining defensive pacts and federations, taking sectors resources, and dealing with factions. Depending on a players' governing ethics and government type, it is also possible to use it to influence elections.

The most common way to spend influence is claiming systems. base cost of claiming a new system (neutral or owned by others) is 75 Influence.png influence, which is increased the further away the system is from one's existing borders.

A normal empire produces a base of 3 Influence.png influence a month, can store only 1000, and the storage amount cannot be increased.

It's much harder to earn extra influence than other basic resources. More influence can be get by declaring rivalries, researching technologies that increase influence output, keeping factions happy, finishing events or anomalies, having protectorates or winning wars using the "Humiliate" and "Stop Atrocity" war goals. It is produced on an empire basis so it doesn't matter if a given system is managed by a sector. Some modifier also allows empire to use influence more efficiently by reducing the influence cost of some actions.

An influence shortage causes an empire-wide −20% Mod pop happiness.png happiness penalty.

Unity is a resource used to acquire traditions, allowing one to progress through tradition trees and gain ascension perks. Note: choosing an ascension perk does NOT spend unity. Unity can also be spent on Ambitions, which are similar to edicts. Ambitions require the Apocalypse.png Apocalypse DLC and the Ascension Theory technology.

Every empire has a base gain of Unity.png +1 Unity. Additional unity is generated by buildings, in particular the Planetary Capital building. Research and traditions can add a number of unity generation buildings. Civics, ethics and certain Traits can also affect unity gain rather drastically. Democratic governments can get extra unity by fulfilling their ruler's mandate.

Unity can be stockpiled, although it will stop accumulating at 2 million.


Research is used to acquire new technologies in the Physics Research Physics, Society Research Society, and Engineering Research Engineering departments. It is also spent on some special projects.

It can be acquired by building research stations and by constructing and upgrading science labs on the surface of planets and moons. It, like Influence.png influence, is produced on an empire basis.

Stored research works totally differently from other stored resources. Storage can only be acquired from any time spent not working on either an active research topic or by finishing special projects, including salvage operations. The moment active research does take place, stored research is used to speed up the progress. For every point of research income, an additional point from the storage is used to effectively double the speed. As such research tends towards 0 storage eventually, while still allowing lump sums to be gained and stored.

Research points gained from anomaly investigation and from salvaging debris are added to the stored research pool; research points are not added to the stored research pool when conducting special projects such as debris salvage or genetic modification.

Strategic Resources[edit]

Strategic.png Strategic resources are rare resources that provide an empire-wide modifier boost. The resources do stack and require an amount modified by your empire size to get the boost. They are also required in quantity to both build and maintain advanced buildings. They can also be traded with other empires and are valued far more than the common basic resources. Strategic resources are always visible but requires specific technology to exploit.


Strategic.png Basic strategic resources can be found on celestial bodies or some special planet features, and they can be synthesized with proper technologies and buildings.

Local resources[edit]

In addition to the global-modifier resources there are also some local resources which provide a certain boost only to the planet they are on. These resources require the construction of a special building on the resource tile to exploit them.
