Coal is a fossil fuel formed from the remains of ancient plants that have been subjected to heat and pressure over millions of years. The term "coal" has been used for centuries, with early references dating back to ancient China and Europe. The name "coal" is derived from the Greek word "anthrakis," meaning "coal" or "charcoal." Over time, the use of coal has evolved from primitive heating and metalworking to its current primary role in electricity generation. The name "coal" is important because it represents a significant source of energy that has shaped human history and continues to play a crucial role in modern society.
