As an expert in the field of environmental science and renewable energy, I have a deep understanding of the impacts of different fuels on our environment. When it comes to the question of which fuel will cause the least pollution when burned, the answer is not as straightforward as it might seem. It involves a complex analysis of the types of pollutants released, the efficiency of combustion, and the overall environmental impact.
Among the list of fossil fuels, natural gas is indeed considered to be the least polluting fuel. This is primarily due to its high hydrogen-to-carbon ratio, which results in more energy being released per unit of carbon emitted. When natural gas is burned, the primary byproduct is carbon dioxide (CO2), which is a greenhouse gas contributing to global warming. However, compared to coal and oil, the amount of CO2 released is significantly less.
Coal, on the other hand, contains nitrogen and sulfur, in addition to a higher carbon content. The combustion of coal releases not only CO2 but also nitrogen dioxide (NO2) and sulfur dioxide (SO2), both of which are harmful pollutants that can contribute to acid rain and respiratory problems. Furthermore, coal combustion can also release particulate matter, which is a significant contributor to air pollution.
Oil, like coal, also has a high carbon content and when burned, it releases CO2, NO2, and SO2, along with other pollutants such as volatile organic compounds (VOCs) and heavy metals. The refining process of oil also contributes to pollution through the release of these and other harmful substances.
In addition to fossil fuels, there are other types of fuels that are considered to be cleaner.
Hydrogen, for example, when produced from renewable sources and burned, produces only water as a byproduct, making it a zero-emission fuel. However, the production of hydrogen can be energy-intensive and currently often relies on natural gas, which introduces some level of pollution.
Biofuels, such as ethanol and biodiesel, are derived from organic material and can be a renewable source of energy. They have the potential to be cleaner than fossil fuels, but their environmental impact depends on how they are produced and the lifecycle emissions they generate.
Electricity, particularly when generated from renewable sources like solar, wind, or hydroelectric power, does not produce direct tailpipe emissions. However, the overall environmental impact must consider the source of the electricity and the emissions associated with the production, transmission, and storage of energy.
When evaluating the least polluting fuel, it is also important to consider the efficiency of the combustion process and the technology used. Advanced combustion technologies and cleaner-burning engines can significantly reduce the amount of pollutants released.
In conclusion, while natural gas is often considered the least polluting fossil fuel, the quest for the least pollution involves looking beyond fossil fuels to renewable and cleaner energy sources. The environmental impact of any fuel is multifaceted and must be assessed in the context of its entire lifecycle, from production to combustion to disposal.

Among the list of fossil fuels, natural gas is considered to be the least polluting fuel. Coal contains nitrogen and sulphur and higher carbon content as well, which ends up releasing excess amount of nitrogen di oxide (NO2),sulphur di oxide (SO2), carbon di oxide (CO2).May 23, 2016
