I believe it was during the Permian and Pennsylvanian eras.
Coal takes millions of years to form from the pressure of dead plants and trees in swamps.
Coal is formed from 400 million year old trees.
Coal is formed from plants, which turned into peat, then lignite, then coal.
Coal begins to form in a humid and warm climate where organic matter, such as dead plants, accumulates in oxygen-poor environments like swamps and wetlands. Over time, the organic matter gets buried and undergoes transformation into peat, then lignite, and finally coal through a process known as coalification.

electricity generation and Coal might form in peat bogs or swamps where vegetation accumulates under anaerobic conditions
Coal can form in swamps and marshes that have abundant plant material, deposition of sediments, and lack of oxygen. The plant material decays and undergoes chemical and physical changes over millions of years, eventually forming peat, which then transforms into coal under high pressure and heat.

Coal beds form from the accumulation of plant material in swamps and wetlands over millions of years. The plant material is buried and subjected to heat and pressure, transforming it into coal. This process typically occurs in areas with high plant productivity and slow decomposition rates.
Coal forms from the accumulation and burial of plant material in oxygen-poor environments, such as swamps and bogs. The lack of oxygen prevents decay and allows the organic matter to undergo transformation into coal through heat and pressure over millions of years.
