What You'll Learn
Natural gas is a fossil fuel
Natural gas is found in underground geological formations, often alongside other fossil fuels like coal and oil. It can be extracted from the ground in its native gaseous form, and its extraction and consumption are major industries. Natural gas is used for heating, cooking, and electricity generation, and it emits fewer toxic air pollutants, less carbon dioxide, and almost no particulate matter compared to other fossil fuels. However, gas venting and unintended fugitive emissions throughout the supply chain can result in natural gas having a similar carbon footprint to other fossil fuels.
The use of natural gas as a fuel source has been criticised due to its contribution to climate change. Both the natural gas itself (specifically methane) and carbon dioxide, which is released when natural gas is burned, are greenhouse gases. Human activity is responsible for about 60% of all methane emissions, and globally, methane accounts for an estimated 33% of anthropogenic greenhouse gas warming. Additionally, cooking with natural gas contributes to poor indoor air quality and can lead to severe respiratory diseases such as asthma.
Synthetic natural gas (SNG) is a fuel gas predominantly composed of methane. It can be produced from fossil fuels such as lignite coal and oil shale or from biofuels using electricity with a power-to-gas system. Renewable natural gas (RNG), also known as biomethane, is a renewable fuel made from biogas that has been upgraded to a quality similar to fossil natural gas. It is chemically identical to fossil-derived conventional natural gas and can be distributed through the existing natural gas pipeline system.

It is formed from the remains of plants and animals
Fossil fuels are compound mixtures formed from the remains of prehistoric dead plants and animals. This phenomenon was first introduced by Andreas Libavius in his 1597 Alchemia and later by Mikhail Lomonosov in the mid-1700s. The term "'fossil fuel" was first used by German chemist Caspar Neumann in 1759.
The process of fossil fuel formation involves the remains of plants and animals being gradually buried under layers of rock and dirt. Over millions of years, the heat and pressure from the Earth's crust decompose these organic materials into one of three primary fossil fuels: oil (also known as petroleum), natural gas, or coal. The type of fossil, the amount of heat, and the pressure determine whether the remains will form oil, natural gas, or coal.
Plants, for example, tend to form coal and methane. Many coal fields date back to the Carboniferous period of Earth's history. Terrestrial plants also produce type III kerogen, a source of natural gas. On the other hand, aquatic phytoplankton and zooplankton that died and settled in large quantities under anoxic conditions played a role in forming petroleum and natural gas through anaerobic decomposition.
Natural gas, a fossil fuel, is formed when organic matter, primarily marine microorganisms, undergoes thermal decomposition in oxygen-free conditions and is subjected to intense heat and pressure underground over millions of years. This process results in the conversion of organic materials into high-carbon fossil fuels. The energy from the sun, which drives photosynthesis in plants and animals, is stored as chemical energy within the molecules of methane and other hydrocarbons.
The formation of fossil fuels can take millions of years, and they are considered non-renewable resources. They have been essential in human development as they can be easily burned in the open atmosphere to generate heat and electricity.

It is the largest component of cooking gas
Natural gas is a fossil fuel formed from the remains of plants and animals, primarily marine microorganisms, that lived millions of years ago. It is composed of various compounds, with methane (CH4) as its largest component. Methane is a hydrocarbon, a compound containing one carbon atom and four hydrogen atoms. It accounts for the majority of natural gas and is highly combustible, making it a valuable fuel source.
Natural gas is formed through the thermal decomposition of organic matter under oxygen-free conditions, subjected to intense heat and pressure underground over millions of years. This process transforms the organic matter into hydrocarbons, releasing the energy stored within the molecules of methane and other hydrocarbons. The energy originates from the sun, which the organisms captured through photosynthesis.
The extraction and consumption of natural gas have become a major industry. It is used for heating, cooking, and electricity generation. While burning natural gas emits fewer toxic air pollutants and carbon dioxide compared to other fossil fuels, it still contributes to climate change. Methane, the primary component of natural gas, is a potent greenhouse gas, and human activity has significantly increased its atmospheric concentration.
Natural gas deposits are often found alongside other fossil fuels like coal and oil (petroleum). It can be extracted from underground geological formations, including shale gas, tight gas, and coalbed methane. The extraction process, such as hydraulic fracturing or fracking, involves forcing water, chemicals, and sand under high pressure to release the natural gas from the rock formations.
Natural gas has been a significant energy source, meeting most of humanity's energy requirements for decades. However, it is considered a non-renewable resource due to the long formation time of fossil fuels and the rapid depletion of known viable reserves. Additionally, the burning of natural gas contributes to indoor air pollution, leading to respiratory diseases.

It contributes to poor indoor air quality
Natural gas is a fossil fuel formed from the thermal decomposition of organic matter, primarily marine microorganisms, under oxygen-free and high-pressure conditions over millions of years. It is composed mainly of methane, a potent greenhouse gas, and is used extensively for cooking, heating, and electricity generation. While burning natural gas emits fewer toxic air pollutants compared to other fossil fuels, its use in cooking contributes to poor indoor air quality and poses significant health risks.
Cooking with natural gas can lead to a decline in indoor air quality due to the release of harmful pollutants and the potential for inadequate ventilation. The combustion of natural gas, particularly in stoves and ovens, produces nitrogen dioxide, carbon monoxide, and fine particulate matter, which are hazardous to human health. These pollutants can irritate the eyes, nose, and throat, leading to respiratory issues and exacerbating existing cardiovascular and respiratory diseases.
Nitrogen dioxide (NO2) is a highly reactive gas formed during the combustion of natural gas. It is a significant component of indoor air pollution, especially in homes with gas stoves. Exposure to NO2 can irritate the respiratory system, leading to coughing, wheezing, and difficulty breathing. Prolonged exposure to elevated levels of NO2 has been linked to increased risk of respiratory infections, reduced lung function, and the development or exacerbation of asthma and other respiratory conditions.
Carbon monoxide (CO) is a colorless, odorless, and toxic gas produced during the incomplete combustion of natural gas. It poses a severe health risk, as it can lead to carbon monoxide poisoning, which occurs when CO is inhaled and accumulates in the bloodstream. Symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, and confusion. High levels of exposure can result in loss of consciousness and even death. Proper ventilation and the use of carbon monoxide detectors are crucial to mitigate these risks.
In addition to nitrogen dioxide and carbon monoxide, cooking with natural gas can also release fine particulate matter, which consists of tiny solid and liquid particles suspended in the air. These particles can be inhaled and penetrate deep into the respiratory system, causing or worsening respiratory and cardiovascular problems. Prolonged exposure to fine particulate matter has been associated with increased risks of asthma, chronic bronchitis, heart disease, and other adverse health outcomes.
The use of natural gas for cooking, therefore, has direct implications for indoor air quality and human health. While it is convenient and widely used, it is essential to ensure adequate ventilation during and after cooking to mitigate the buildup of these harmful pollutants. Additionally, regular maintenance and proper functioning of gas appliances are crucial to minimize the release of these pollutants and protect the well-being of occupants.

It is a growing contributor to climate change
Natural gas is a fossil fuel formed from the thermal decomposition of organic matter, primarily marine microorganisms, over millions of years. It is widely used for cooking, with over 40 million homes in the US alone cooking with gas.
Cooking with natural gas contributes to climate change in several ways. Firstly, burning natural gas releases carbon dioxide, the most prevalent greenhouse gas, into the atmosphere. While natural gas emits less carbon dioxide than other fossil fuels, it still contributes significantly to global warming and ocean acidification. Secondly, natural gas leaks, both during the extraction and storage process, and from cooking appliances, release methane, a potent greenhouse gas with a global warming potential 86 times that of carbon dioxide over a 20-year period. Methane emissions from gas stoves are significant, with studies showing that gas stoves emit methane even when switched off, and the total emissions equivalent to about 500,000 cars' worth of carbon dioxide annually.
The use of natural gas for cooking is a growing contributor to climate change due to the increasing awareness of its impact. While natural gas was once considered a cleaner alternative to other fossil fuels, recent studies have highlighted the significant methane emissions associated with its use. The term "fossil gas" or "methane gas" has been proposed to better convey its climate impact to the public.
Additionally, cooking with natural gas contributes to poor indoor air quality, releasing nitrogen oxides, carbon monoxide, formaldehyde, and fine particulates, which can cause or exacerbate respiratory problems. The health risks associated with indoor air pollution from natural gas cooking further emphasize the need to transition to cleaner energy sources.
To address the growing contribution of cooking gas to climate change, renewable energy advocates promote switching to electric appliances, which will facilitate the transition to clean energy sources and improve indoor air quality. While gas stoves may not be banned outright, regulatory bodies can implement measures such as requiring the use of fume hoods or improving pipe fittings to prevent leaks and reduce emissions.
