The sources of energy and their importance

The sources of energy

The Sun is the main source of energy, and it is very important in our life, but there are resources of energy which are the renewable sources of energy and the non-renewable sources of energy, They are very important in our life.

The renewable resources of energy are the sources of energy that renew themselves.

Examples of renewable resources of energy:

Electricity generating by windmills

Electricity generating by windmills

  1. The wind energy is used in rotating the windmills to generate the electricity.

  2. The rising and ebb tides energy which is caused by the moon. The energy produced from rising the level of the sea and its returning back is used in rotating the turbines that operates the generators (dynamo) to produce the electricity.

  3. The waterfalls energy which generates the energy that moves the turbines to operate the dynamo to get the electricity.

What are the machines that are rotated by the renewable resources of energy?
  1. The windmills that work by wind energy.

  2. The turbines that work by the waterfalls energy and rising and ebb tidies energy.

The non-renewable resources of energy are the sources of energy that may be exhausted by the continuous use and they do not renew themselves. 

Examples of the non-renewable resources of energy:

The coal, the petroleum oil or its derivatives and the natural gas.

The natural gas is one of the cleanest forms of fuel because it causes less pollution for the environment, So the government exerts a great effort to increase its production.

The government gives more attention to the use of natural gas instead of gasoline.

What are the machines that are rotated by the renewable resources of energy?
  1. Cars that work by benzene (derivative from the petroleum) or the natural gas.
  2. The aeroplanes that work by benzene (derivative from the petroleum).
  3. The irrigating machines that work by kerosene.
