Coal is also used as a power source for factories. There it is used to heat steam, and the steam is used to drive mechanical devices. A few decades ago most coal was used for space heating. Some coal is still used that way, but other fuels and coalproduced electricity are now used instead. Coke production remains an important use of coal.
