Coal is a combustible sedimentary rock composed mainly of carbon, hydrogen, and oxygen. It is formed from the remains of dead plants and animals that have been buried and subjected to high pressure and heat over millions of years.
The energy industry is the largest user of coal in the world. Coal is primarily used for electricity generation, accounting for around 38% of global electricity production. Coal-fired power plants are found in many countries, and they operate by burning coal to heat water and produce steam, which drives turbines to generate electricity.
In addition to electricity generation, coal is also used in industrial processes such as steel production and cement manufacturing. Coal is an important source of energy for these industries due to its high heat content and relatively low cost.
However, the use of coal has come under scrutiny in recent years due to concerns about its environmental impact. Burning coal releases carbon dioxide and other pollutants into the atmosphere, contributing to global climate change and air pollution. Many countries are transitioning away from coal and towards cleaner forms of energy, such as wind and solar power. Nonetheless, coal remains an important energy source in many parts of the world, particularly in developing countries where electricity demand is growing rapidly.
