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

The importance of the Sun

Do you see the Sun in the sky in the morning every day? Do you know the importance of the Sun? The Sun is the main source of the energy on the Earth and solar energy is the cleanest form of energy.

The benefits of solar energy

Sun importance

The solar cells are used to generate the electricity

  1. The Sun is very important in the plant’s 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.

  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 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’t carry them, So the rain falls.

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

  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 wind energy into 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 Sun is used to generate the electricity by the solar cells and the windmills, The solar cells change the solar energy into the electric energy.

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