Aardgas, or natural gas, is a fossil fuel primarily composed of methane. It is found deep beneath the Earth's surface, often in association with other fossil fuels like oil and coal. Aardgas is extracted through drilling and is used for various purposes, including heating, electricity generation, and as a fuel for vehicles. This energy source is considered cleaner than other fossil fuels, as it produces fewer carbon emissions when burned. Aardgas plays a significant role in the global energy market and is a key component in the transition towards more sustainable energy solutions, such as renewable energy.
