Oil Energy

Oil energy is a non-renewable source of energy. It is a fossil fuel. Other fossil fuels are coal and natural gas. Oil has been used for more than 5000 years. Oil energy is mostly used in cars and various other automobiles.

Oil energy source

  • We will discuss here about the formation of oil.
  • Millions of years ago, many animals and plants inside the ocean store energy from the sun in the form of carbon.
  • As years go by, these animals and plants die and settle at the bottom of the ocean.
  • As the pressure and heat at the bottom of the ocean increases, due to the formation of various sediment layers, these animals and plants gets converted into oil containing high carbon content.
  • The oil we get from this source is known as crude oil.

Oil energy pros and cons


  • Oil is an extremely powerful energy source.
  • Oil produces high energy output. That is why it is used in automobiles widely. A study shows that oil can move vehicles faster and longer than any other energy sources.
  • Oil has lots of impact on global economy. Most of the middle-east countries are rich only because they have lots of oil reserves.
  • As of now, oil is abundantly available.
  • Since oil is in liquid form, it is easier to transport.

Oil energy pros and cons


  • Oil emits carbon dioxide during combustion, which is the main reason for global warming.
  • Oil must drilled out from the ground and from the ocean. These drilling activities might cause problems to terrestrial and aquatic habitats.
  • Oil spills in the ocean cases serious problems.
  • It is non-renewable. It cannot be used again.
  • Using oil may cause serious environmental problems.

Oil energy facts

  • U.S.A. consumes most of the oil produced. Next comes European Union. U.S.A. uses a maximum of 20 million barrels of oil per day. European Union uses 13 million barrels of oil per day.
  • 75% of world’s oil reserves are present in the Middle East countries.
  • Based on data from OPEC at the beginning of 2013 the highest proved oil reserves including non-conventional oil deposits are in Venezuela (20% of global reserves), Saudi Arabia (18%), Canada (13%), and Iran (9%).
  • Oil has been used for more than 5000-6000 years.
  • Distillation is the process by which many by-products of crude oil are created. Various by-products are petrol, diesel, kerosene, natural gas, oil for lubrication.

Oil energy alternatives

  • Oil energy is mightily useful. But it is non-renewable and it causes global warming. So people are going for other alternatives.
  • Nuclear energy is one such alternative. It produces a large amount energy due to fission and fusion.
  • Solar energy is a green alternative. It is called green alternative because it is pollution free and it is available everywhere.
  • Various other alternatives are hydro energy, wave energy, geo-thermal energy, ocean energy, wind energy.

Oil energy uses

  • Oil is mostly used as automobile fuel. It is because it produces the best output when compared to other alternatives. The oil which is used in vehicles are known as petrol and diesel.
  • Oil is also used for generating electricity in some places. The oil is burnt to produce a lot of heat for producing steam, which is used to run turbines which in turn produces electricity.
  • Crude oil is used in many industrial products like in detergents, in fertilizers, paints, plastics, petroleum products, medicines and in the formation of synthetic rubber.

Oil energy crisis

  • An energy crisis is any great bottleneck (or price rise) in the supply of energy resources to an economy.
  • Oil energy crisis is due to depletion of oil resources and increase in the oil prices.
  • We need other alternative sources of energy for this depletion.
  • “Peak oil” is the period when the maximum rate of global petroleum extraction is reached, after which the rate of production enters terminal decline.
  • When this peak oil stage is reached, then it means that the world is in serious oil crisis.
