Coal, oil, and natural gas are fossil fuels formed from ancient organic materials. Coal is a solid fuel primarily used for electricity generation and industrial processes. It is mined from the ground and can release significant amounts of carbon dioxide when burned. Oil, often referred to as petroleum, is a liquid fossil fuel used for transportation, heating, and producing various products like plastics. Natural gas is a cleaner-burning gas used for heating, electricity generation, and as a raw material in chemical production. Together, these fuels play a crucial role in the global energy landscape.
