That’s largely because of the shale gas revolution, which suddenly made natural gas cheaper than coal for generating electricity. … Global coal use continues to rise, especially in developing economies. About 38 percent of global electricity comes from coal, and in many countries it’s a mainstay for industrial uses, too.
How is coal formed and what are its uses?
Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. … Coal is primarily used as a fuel. While coal has been known and used for thousands of years, its usage was limited prior to the Industrial Revolution.

The process of coal formation is still taking place today, says Bailey. “The precursor to coal is called peat, and that is just uncompressed plant matter.” Peat accumulates in wet swampy environments known as mires, and that process is taking place today in areas such as Indonesia and even the Antiplano in the Andes.
What are the disadvantages of coal?
The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
