Coal is a fossil fuel that has been used for centuries to generate electricity, heat homes and businesses, and power industrial processes. It is a complex mixture of organic materials, including carbon, hydrogen, oxygen, nitrogen, and sulfur. Coal is formed from the remains of plants that lived millions of years ago. Over time, these plants were buried under layers of sediment and subjected to heat and pressure, which transformed them into coal.
Coal is an important source of energy for many countries around the world. It is relatively inexpensive to mine and transport, and it can be used to generate electricity and heat efficiently. However, coal is also a major source of pollution, and its use has been linked to climate change. As a result, many countries are moving away from coal and investing in renewable energy sources.
