What You'll Learn
Natural gas is the cleanest-burning fossil fuel
Natural gas is a fossil fuel derived from organic material buried in the Earth millions of years ago. It is a major source of energy in the US, with over 65 million American homes using it. Natural gas is the cleanest-burning fossil fuel, offering a clean burn with minimal particulate matter.
Compared to other fossil fuels, natural gas is cleaner and more efficient. It produces fewer harmful emissions, with natural gas emissions primarily composed of water vapour and carbon dioxide. While carbon dioxide is a significant contributor to air pollution, natural gas burned in newer, more efficient power plants emits 50-60% less carbon dioxide than traditional coal plants and up to 30% less than oil. Additionally, natural gas produces less sulfur dioxide and nitrogen oxide, further contributing to its cleaner air impact profile.
Natural gas also has a high efficiency rate of 92% from wellhead to home, compared to coal-generated electricity, which operates at only 32% efficiency. This efficiency, along with its abundance in North America, makes natural gas a cost-effective energy source. According to the American Gas Association (AGA), natural gas is not only used to generate cleaner energy but also serves as a raw material for creating environmentally friendly products, such as lightweight cars, wind power blades, and solar panels.
However, it is important to acknowledge that leaks of methane from natural gas pipelines can be a significant source of greenhouse gas emissions. Methane has a more substantial impact on climate change than CO2 per pound. While a 1997 study by the EPA and GRI suggested that reduced CO2 emissions from natural gas outweighed methane leaks, more recent data is needed to understand the current climate change effects of natural gas compared to other fossil fuels.
In summary, natural gas is the cleanest-burning fossil fuel due to its minimal emissions, high efficiency, and versatility in energy generation and manufacturing. However, the potential impact of methane leaks from natural gas infrastructure underscores the importance of transitioning to primarily renewable and sustainable energy sources.

It produces fewer harmful emissions than oil and coal
Natural gas is the cleanest-burning fossil fuel. It produces fewer harmful emissions than oil and coal, making it a cleaner energy source. Natural gas is composed mostly of methane, which is released when it is burned. While methane contributes more to climate change than carbon dioxide, natural gas still emits fewer greenhouse gases overall.
Burning natural gas results in fewer emissions of almost all types of air pollutants and carbon dioxide (CO2) than burning coal or petroleum products to produce an equal amount of energy. For every 1 million British thermal units (Btu) consumed, coal produces over 200 pounds of CO2, while fuel oil produces over 160 pounds. In comparison, natural gas emits nearly 90,000 fewer pounds of CO2 per billion Btu than coal.
Natural gas also produces less sulfur dioxide and nitrogen oxide than oil, making it a cleaner option for the atmosphere. It has a 92% efficiency rate from the wellhead to home, compared to electricity generated by coal, which only operates at a 32% efficiency rate. This makes natural gas not just cleaner but also more cost-effective.
The clean-burning properties of natural gas have contributed to its increased use for electricity generation and fleet vehicle fuel in the United States. However, it is important to note that leaks of methane from natural gas pipelines and infrastructure can still contribute significantly to greenhouse gas emissions. While natural gas is the cleanest-burning fossil fuel, it is still a non-renewable resource that pollutes the environment and contributes to climate change.

Natural gas is more energy-efficient than other fossil fuels
Natural gas is a fossil fuel, derived from organic material buried in the Earth millions of years ago. It is a major source of energy in the US and is used by several sectors. Natural gas is produced from reservoirs deep beneath the Earth's surface and has become increasingly popular over the past 50 years due to its convenient and economical delivery via pipelines.
Natural gas is also cleaner than other fossil fuels. It produces fewer harmful emissions, including less carbon dioxide, sulfur dioxide, and nitrogen oxide. When burned, it produces 45% less carbon dioxide than coal, 30% less than oil, and 15% less than wood. However, it is important to note that leaks of methane, a potent greenhouse gas, from natural gas pipelines and facilities can contribute significantly to climate change.
While natural gas is the cleanest fossil fuel, it is not as clean as wind or solar power. It is considered a key ingredient in the world's transition to cleaner energy. In many countries, natural gas has already replaced coal as the preferred fuel for electricity production, improving climate and air quality. However, the transition to renewable energy sources must be rapid to avoid the worst consequences of climate change.

It is also cost-effective and domestically abundant in the US
Natural gas is the cleanest-burning fossil fuel. It produces fewer emissions of nearly all types of air pollutants and carbon dioxide (CO2) compared to other fossil fuels like coal and petroleum products. It also produces less sulfur dioxide and nitrogen oxide than oil. In addition, natural gas produces more energy than any other fossil fuel, with a 92% efficiency rate from wellhead to home, compared to electricity generated by coal, which operates at only a 32% efficiency rate.
Natural gas is also cost-effective. It is one of the greatest domestic energy sources in the US, with around 90% of the natural gas consumed in the country produced domestically, and nearly 100% produced in North America. Natural gas is the leading energy choice for American homes and industries, with over 65 million homes in the US using it. It is also the most economical source for home energy needs, costing one-third as much as electricity.
Natural gas is also used as a raw material to manufacture a wide variety of products, from paint to fibres for clothing and plastics for healthcare. Its molecular disposition also makes it useful for creating green materials such as lightweight cars, wind power blades, and solar panels.
The popularity and use of natural gas have increased dramatically over the past 50 years as pipeline infrastructure has been installed to deliver it conveniently and economically to millions of residential, commercial, and industrial customers worldwide. However, it is important to note that leaks of methane (CH4) from natural gas pipelines may contribute significantly to greenhouse gas emissions. While a 1997 study by the EPA and GRI estimated that the decreased CO2 emissions from natural gas outweighed any greenhouse gas emissions from methane leaks, more conclusive studies are needed to compare the climate change effects of natural gas and other fossil fuels.

However, methane leaks from natural gas pipelines contribute to climate change
Natural gas is widely considered the cleanest fossil fuel. It is more efficient than other fossil fuels, with a 92% efficiency rate from wellhead to home, compared to electricity generated by coal, which operates at only a 32% efficiency rate. Natural gas is also cost-effective and abundant in the US, with around 90% of the natural gas consumed in the US produced within the country.
Methane is a potent greenhouse gas that traps more heat in the atmosphere per molecule than carbon dioxide (CO2). Due to its heat-trapping ability, methane contributes more to climate change than CO2 on a per pound basis. Even small leaks of methane may make natural gas contribute more to climate change than coal. While methane has a much shorter lifespan than CO2, staying in the atmosphere for about a decade compared to hundreds of years for CO2, it is 80 to 100 times more harmful than CO2 in the 20 years after it is released into the atmosphere.
The oil and gas industries are major producers of methane, emitting the gas during drilling, production, and other operations. Massive methane leaks, known as super-emitter events, have occurred at oil and gas fields worldwide, often due to equipment failures. These super-emitter events can last for weeks, releasing large amounts of methane into the atmosphere.
While there is a growing emphasis on methane reduction, with initiatives such as the Oil and Gas Climate Initiative, addressing methane leaks in natural gas pipelines remains challenging. Replacing and repairing leaking pipelines can be costly, especially in populated cities. However, improvements to the natural gas system are technically possible, and efforts to reduce methane leaks can have a significant impact on mitigating climate change.
