What is Coal?
Coal is a naturally occurring combustible material composed of carbon, hydrogen, and oxygen and other elements It is one of the world’s most abundant sources of energy and has been used by humans throughout history. Coal was once the primary source of energy for factories, homes, and transportation and is still used extensively today in electricity generation, steel production, and other applications.
Coal is formed from the remains of plants and animals that have been buried and exposed to intense heat and pressure for millions of years. This process produces a hard, dense material that is usually black or dark brown in color. Coal contains high levels of carbon and other combustible elements, creating the potential for significant heat energy when it is burned.
Though coal is still used for energy production, the environmental challenges associated with its use have caused many countries to move away from it towards renewable energy sources. Burning coal produces greenhouse gases, which contribute to global warming, and the mining processes can have a negative impact on local ecosystems. Despite its challenges, coal will remain a part of the energy landscape for many years to come, and it is important to understand how it works and how it can be used responsibly.
