In the present generation, there is a great demand and prime importance for electricity. The earth has been polluted to higher degrees because of the various methods employed for power production. There is a necessity to produce power using other sources li0ke green energy and alternative energy. Human needs can be satisfied by technology usage but it should not affect the system. Wind has become a main resource in producing such a clean energy and it satisfies the necessity of human beings as one of the alternative source to extract the power. Due to the temperature differences across the earth's surface, the hot air rises up and cool air fills the void. There are various phenomenons' that cause wind to flow across the globe. Wind is available abundant in nature and considered as main source because of its constant occurrence, clean in nature, inexhaustible, green energy in status and hence it can be harnessed. At the equatorial zone, the earth surface gets heated up which cause air above it to get heated up, causing wind to blow higher due to which the pressure gets down, the cool air near the poles rush towards the equator. This is known as geostrophic wind. This can be observed at higher altitudes.
