GEOLOGY

Detailed explanation-1: -When natural gas is burned, it produces mostly carbon dioxide and water vapor–the same substances emitted when humans exhale. Compared with some other fossil fuels, natural gas emits the least amount of carbon dioxide into the air when combusted–making natural gas the cleanest burning fossil fuel of all.

Detailed explanation-2: -Comparison of Emissions for Fuel Sources In terms of emissions from power plant sources, natural gas is the cleanest fossil fuel.

Detailed explanation-3: -Methane Emissions Natural gas is the cleanest burning hydrocarbon fuel that produces roughly half of the CO2, compared to coal, and about 20% less than oil.

Detailed explanation-4: -Natural gas, which primarily consists of methane, is the cleanest burning fossil fuel. When methane is produced from non-fossil sources such as food and green waste, it can literally take carbon out of the air.

Detailed explanation-5: -LPG burns with a blue smokeless flame and leaves no ash behind. So, it does not cause any pollution. Therefore, LPG is a clean fuel. It does not produce any poisonous gases on combustion.
