Coal is one of the first ores you will encounter.
It is used for power, and in some basic crafting recipes.
Depending on your chosen difficulty there might be an Ore Extractor operating on a Coal Vein. While in the starting tutorial the game explains how to use it and set up a small basic automated coal cycle.
Coal will be your main power source through most of your gameplay.
You can search for more coal using your Ore Scanner.
