Coal originated from ancient plants that flourished in swamp-like environments millions of years ago. In Virginia, coal was formed mainly during the Carboniferous period of the Earth's history, 280 to 360 million years ago. There are also coalbeds in Virginia that were formed during the Triassic period, 205 to 245 million years ago. By comparison, most of the coals in the western U.S. were formed during the Cretaceous period, 70 to 140 million years ago, and the Tertiary period, 2 to 70 million years ago.
rock coal
Coal is obviously a fossil fuel; it is believed to have formed from te fossilised remains from animals and plants from the Carboniferous Period.
Rapid accumulation, chemical alteration, and oxygen deficient environment.
It is a sedimentary rock, but the harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. It is composed primarily of carbon along with assorted other elements, including sulfur.

organic matter (dead plant and animal matter)
Because of their organic origin
The word carbon comes from carbo, the Latin word for coal.
coal, some limestones are from plant types of diatoms.
Graphite, coal and diamonds are all thought to be products of the decay and compression of vegetable matter from millions of years ago. Diamonds progress from coal.
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.
