Natural Gas

  • It is a colorless and odorless gas that can be easily transferred through pipelines.
  • It is clean and non-toxic in nature.
  • Under high pressure it is stored as compressed natural gas (CNG) .
  • It is also a less polluting and a less expensive fossil fuel.
  • One of the most useful and important natural gas is Methane.
  • It is a product of decomposed organic matter formed typically from ancient marine microorganisms being deposited over the last 550 million years ago.

Uses of Natural Gas

  • Compressed natural gas is significantly used for generating power.
  • CNG is also used in the automobiles as fuels.
  • In homes it is used for cooking purpose.
  • It is also sued as the starting material in fertilizers and chemicals.

Advantages of Fossil Fuels

  • Fossil fuels have become safer over time.
  • Through pipelines the transportation of fossil fuels can be done easily.
  • These are cost effective and can be found very easily.
  • These are available in plenty despite being a finite resource.

Disadvantages of Fossil Fuels

  • The carbon dioxide emitted on burning of fossil fuels is a major greenhouse gas and the primary source of pollution.
  • Once used these fossil fuels cannot be reused i.e. they are a non-renewable resource.
  • The environment becomes more acidic due to the combustion of fossil fuels.
  • The coal miners suffer from the Black Lung Disease.

Fossil Fuels Are Non-Renewable

  • They can be found everywhere from the air we breathe to the water in the seas.
  • Most of the energy used by humans comes through burning of fossil fuels.
  • The fossil fuels are not being regrown with the same rate as their consumption.
  • Their demands are increasing and hence it is becoming difficult to replace them.

Three major types of fossil fuels are:

i) Coal

ii) Petroleum

iii) Natural gas

Q 3. List out some of the disadvantages of fossil fuels.

Answer: Some of the disadvantages of fossil fuels are:

i) They emit carbon dioxide a major source of air pollution.

ii) They cannot be sued twice being a non-renewable resource.

iii) Harvesting of fossil fuels also causes fatal diseases among the people.
