Coal is a resource that is widely used in the refining of base ores into metals and smelting into weapons. Coal is initially only produced in a Coking House that charcoals Pinewood and later it also comes directly from Coal Mines.
The coking plant is the first building available which produces coal. It consumes Pinewood, converting it to Coal. It does not require any other deposit to be searched for.
The coal mine is a building placed onto a coal resource. The coal resource needs to be found by an Explorer. There are three coal deposits in Sector 6, and three in Sector 7.
The Recycling Manufactory produces coal from nothing. It produces coal at the same rate as the Coking Plant, but does not consume any Pinewood.
