The primary gas in natural gas is methane, a hydrocarbon compound with the chemical formula CH4. Methane constitutes about 70-90% of natural gas and is produced both naturally through geological processes and artificially during the extraction of fossil fuels. It is considered a cleaner-burning fuel compared to other fossil fuels like coal and oil. When burned, methane produces carbon dioxide and water, releasing energy that can be harnessed for heating, electricity generation, and various industrial processes. However, methane is also a potent greenhouse gas, contributing to climate change, emphasizing the importance of managing its emissions responsibly.
