Natural gases are a type of fossil fuel primarily composed of methane, a colorless and odorless gas. They are formed from the remains of ancient plants and animals buried under layers of sediment for millions of years. Natural gases are found deep beneath the Earth's surface and are often extracted through drilling. These gases are used widely for heating, cooking, and generating electricity. They are considered a cleaner alternative to other fossil fuels like coal and oil, as they produce fewer greenhouse gas emissions when burned. Natural gases play a significant role in the global energy market and are a key component of energy production.
