What are the properties and uses of coal and fossil fuel?

Coal and fossil fuels, such as oil and natural gas, are primarily composed of carbon and are formed from the remains of ancient organisms. They are energy-dense and have high calorific values, making them efficient sources of energy for electricity generation, heating, and powering vehicles. However, their combustion releases greenhouse gases and pollutants, contributing to climate change and air quality issues. Consequently, while they have been essential for industrial development, there is a growing push for cleaner and renewable energy alternatives.
