Gas natural, or natural gas, is a fossil fuel primarily composed of methane. It is found deep beneath the Earth's surface, often alongside oil deposits. Natural gas is extracted through drilling and is used as a source of energy for heating, cooking, and electricity generation. It is considered a cleaner alternative to other fossil fuels, producing fewer greenhouse gas emissions when burned. Natural gas is transported through pipelines and can also be converted into gas natural licuado (LNG) for easier shipping. It plays a significant role in the global energy market and is an important resource for many countries, contributing to energy security and economic growth.
