What is the importance of the Sun ( solar energy ) ?

The Sun is very important in our life .

Do you see the Sun in the sky in the morning everyday ?

 

Do you know the importance of the Sun ?

 

Everybody know that the Sun is the main source of the  energy on Earth .

 

Look at the Sun , and you must know that the solar energy is the cleanest form of the energy .

 

The benefits of the solar energy 

 

1. The Sun is very important in the plants growth . The Sun helps the plants to make their own food by the photosynthesis process .

    

    

2. The Sun is very necessary for the other living organisms that it provides us with light for the vision and to do our work .

    

   The Sun provides us with the heat to warm our bodies . 

    

   The ٍSun provides some animals and humans ( that feed on plants ) with food as it helps the plants to make its own food by the photosynthesis process .

    

3. The Sun is used in heating water and warming houses  by the solar heater which changes the solar energy of the Sun into the  heat energy . The heat energy is used in warming houses and heating water .

   

   The solar heater changes the solar energy of the Sun into the heat energy .

     

4. The Sun is very important in the formation of the clouds , the rain and the winds .

    

   When the Sun evaporates the water in the seas , the lakes and the oceans ,  the water vapour is formed . and the clouds are formed  When the water vapour rises in the sky , it cools and condenses forming the clouds .

   

   The formation of the clouds and the rain  .

   The Sun's heat causes the difference in the temperature in some areas , So the winds are formed .

    

   The clouds move by the effect of the winds and when the volume of the water drops in the clouds increase and the air can not carry them , So the rain falls .

    

5. The Sun is very important in the formation of the petroleum oil and the coal . It is one of the main factors in the formation of the fuel .

   

   The Sun is very important in the formation of the petroleum oil and the coal .

    

6. The Sun helps in the formation of fuel to operate the machines . 

    

7. It is advisable to expose the children to the Sun rays for suitable periods of time as the Sun emits  ultraviolet rays that help in the formation of vitamin " D " that is necessary for the bones growth .

    

8. The Sun is used  to generate electricity by the windmills .

    

   The windmills change the wind energy into the electric energy . 

    

   The wind that is produced by the Sun is used in rotating the windmills which are used to operate the generators ( dynamo ) to generate the electricity . 

    

   

   The windmills are used to generate the electricity .

   You should know that the Sun is used to generate the electricity by the solar cells and the windmills .

   

   The solar cells are used to generate the electricity .

   The solar cells change the solar energy into the  electric energy . 

    

So , We can not live on Earth without the Sun .
