The sources of energy and their importance



We have known that the Sun is the main source of energy , and it is very important in our life .

 

But you should know that 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 the renewable resources of energy :

 

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


    The windmills
    Electricity generating turbines .

      
  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 .

    The rising and ebb tidies energy
    The moon causes the occurrence of the rising and ebb tides .

     

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

The water falls energy
The waterfalls energy is a renewable resource energy .

What are the machines that are rotated by the renewable resources of energy ?

 

  1. The windmills that work by the 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 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 .

 

You should know that the natural gas is one of the cleanest forms of the 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 the 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 .

     

    The cars
    The cars work by benzene or natural gas .

      

  2. The Aeroplanes  that work by benzene ( derivative from the petroleum ) .

    The planes
    The aeroplanes work by benzene .

      

  3. The irrigating machines that work by kerosene .
