gaasikütuse

Gaasikütuse, often referred to as natural gas, is a fossil fuel composed primarily of methane. It is extracted from underground reservoirs and is widely used as a source of energy for heating, electricity generation, and industrial processes. Its formation involves the decomposition of organic matter over millions of years under intense heat and pressure.

The primary component of natural gas is methane (CH4), with smaller amounts of other hydrocarbons like ethane, propane, and butane, as well as non-hydrocarbon gases such as nitrogen and carbon dioxide. It is typically found alongside crude oil deposits but can also exist in standalone reservoirs. Extraction involves drilling wells into these underground formations.

Once extracted, natural gas is purified to remove impurities before being transported through a network of pipelines to consumers. It can also be liquefied into liquefied natural gas (LNG) for easier transport over long distances via ships. Its combustion produces relatively lower greenhouse gas emissions compared to other fossil fuels, although methane leakage during production and transportation remains a concern.

In many regions, natural gas is the preferred fuel for residential heating and cooking due to its efficiency and relatively clean burning characteristics. It also plays a crucial role in industrial sectors for powering machinery and as a feedstock for chemical production. The global demand for natural gas continues to be significant, making it a key player in the world's energy landscape.
