The main gas found in natural gas is methane (CH4), which comprises about 70-90% of its composition. Methane is a simple hydrocarbon that serves as a significant source of energy for heating, cooking, and electricity generation. Natural gas is often regarded as a cleaner alternative to other fossil fuels, such as coal and oil, because it emits fewer pollutants and greenhouse gases when burned. Additionally, natural gas can be harnessed for various purposes, including as a feedstock in chemical production and as a fuel for vehicles, making it a versatile and increasingly vital energy resource.
