           Fossil Fuels: Advantages and Disadvantages

    The discovery of fossils for energy purpose has turned the wheel of revolution in the history of mankind. Fossil fuels have the capacity to satisfy the energy demands of the entire world for several hundred years. The modern world greatly owes its technological and mechanical progress to fossil fuels.

Fossil fuels are the remains of plants and animals from the prehistoric era, which have now reduced to hydrocarbon chains. These hydrocarbons are in the form of solids or liquids. Fossil fuels have a very high combustion rate and they release tremendous amount of energy. Most of our fuel and energy demands are met by the fossil fuels.

Fossil fuels have several advantages over other sources of energy:

 Fossil fuels have a very high calorific value.

 The reservoirs of fossil fuels are pretty easy to locate.

 Transportation of fossil fuels that are in liquid or gaseous forms is very easy.

Fossil fuels are easier to extract and process.

The disadvantages of fossil fuels are as follows:

 The hydrocarbons present in the fossil fuels, release greenhouse gases.

 Harmful gases such as carbon monoxide and sulfur dioxide are responsible for           

 acid rain.

 Extraction of fossil fuels has endangered the environmental balance in some areas.

 Leakage of some fossil fuels, such as natural gas, crude oil can lead to severe   

 hazards.
