What is one of the three most commonly utilized fossil fuels?

Fuel gas is indeed one of the three most commonly utilized fossil fuels. Typically derived from natural gas sources, fuel gas primarily consists of methane and can be used for various applications, including heating, cooking, and generating electricity. Its efficiency and relatively low emissions compared to other fossil fuels have made it a popular choice in domestic and industrial energy systems.

In the context of other fossil fuels, coal and fuel gas are more commonly referenced due to their widespread usage in energy production and heating. Peat, while it is a fossil fuel, is less commonly utilized on a large scale compared to coal and natural gas. Uranium, on the other hand, is not a fossil fuel; it is used primarily for nuclear energy production. This distinction clarifies why fuel gas is recognized as a prevalent option among fossil fuels used today.
