Natural gas is an invisible fuel found trapped inside rocks deep underground. It does not have any color or natural smell. Because people cannot smell it, gas companies add a harmless chemical that smells like rotten eggs. This special smell helps people notice gas leaks quickly and stay safe in their houses.
Natural gas is mostly made of a simple gas called methane. Millions of years ago, heat and pressure transformed ancient plants and microscopic sea life into this clean fuel. Today, natural gas is very popular because it burns cleaner than coal or oil. When natural gas burns, it releases heat and creates less smoke, soot, and dirty air.
Many families use natural gas in their daily routines. It flows through underground pipes directly into kitchens and basements. In the kitchen, it fuels stoves and ovens to cook hot meals for breakfast, lunch, and dinner. In the basement, water heaters use it to provide warm showers on cold mornings. Large home heating systems also burn natural gas to keep bedrooms cozy during winter. Additionally, huge power stations burn natural gas to create electricity for cities, schools, and offices worldwide.
