Coal is a natural resource most commonly obtained through mining. It is primarily useful in the production of Molten Iron and Molten Copper with additional uses in Cement, Diesel, Molten Glass, Molten Silicon, Rubber. and Graphite.
In the very early game, players will typically create Coal by the burning of Wood in a Coal Maker until they have sufficient resources to mine it directly. However, Wood is also required for the crafting of Construction Parts so burning all of the trees on the island can lead to significant hurdles in building infrastructure.
Island reserves
Each island map contains varying amounts of natural resources. This amount is modified by the resources size modifier on the Map Selection screen while the amount which can be extracted per tile is further affected by the ore mining yield modifier on the Game Difficulty screen. Neither modifier can be changed once the island has been founded.
| Resource | New Haven | The Beach | The Golden Peak | You Shall Not Pass |
|---|---|---|---|---|
| Coal | 1,300,000 | 1,700,000 | 1,600,000 | 2,300,000 |
| Copper Ore | 910,000 | 2,300,000 | 1,600,000 | 5,100,000 |
| Dirt | 1,900,000 | 4,100,000 | 2,000,000 | 4,400,000 |
| Gold Ore | 340,000 | 880,000 | 7,300,000 | 13,400,000 |
| Iron Ore | 1,100,000 | 3,000,000 | 2,100,000 | 5,400,000 |
| Limestone | 930,000 | 1,100,000 | 1,800,000 | 7,900,000 |
| Rock | 14,600,000 | 30,500,000 | 17,700,000 | 69,600,000 |
| Sand | 2,800,000 | 2,800,000 | 2,000,000 | 5,700,000 |
It should be noted that most of the above natural resources are non-renewable, though the following exceptions apply:
- Dirt can be created renewably from Food processed in an Anaerobic Digester.
- Dirt can be created non-renewably from Waste Water processed in a Wastewater Treatment, but with the consumption of Sand.
- Sand can be created non-renewably from Rock by processing it in a Crusher to produce Gravel, then crushed again into Sand.
- While non-renewable, it should be noted that it is very unlikely that the island will run of Rock before either Iron Ore or Copper Ore.
