Then days ago
Possibly 3,000 to 4,000 years ago. Wow. In funeral pyres. In the second century (100 AD) coal is mentioned as a heating source in England. See links.
Coal began to replace the wood in the 1800s because the wood became scarce in some places. in the 1900s coal replace wood as a chief energy source because of its many used such as the fuel for steam engines which powered the many railroad engines popular during the period, and fuel for the steam turbines used in the production for electricity.
Not sure if this will answer your question, but I'll give it a shot. It's less about the fact that is is coal and more about the fact that coal gives off heat. When coal was first being used as a heat source, it was cheaper than wood and there was a lot of it. So really the origin of the energy is in the heat that the coal generates when on fire and less about the coal itself.

In coal mines.
In the Victorian Era, the majority of power was generated by steam, which was done by burning coal. The increased urbanization and Industrial Revolution created the need for much more power, and therefore more coal to generate it.
