In This Video :
Using energy of the wind
Different amounts of solar energy (especially radiant energy) reach different regions of the world.


Radiant energy causes the air around the globe to heat up to different degrees, where the difference in temperature between cold and hot air causes air to move and wind to blow.


Kinetic energy of the wind movement is used to rotate the blades of windmills.

When the windmill blades rotate, this causes wind turbines inside the windmill to rotate, generating electrical energy that is transmitted through huge wires in power lines to different places such as houses and factories.


بالتوفيق
