Question

what is a wind and what it's effect

Answer 1

wind effect varies is exponential in troposphere i.e with respect to height wind velocity varies in an exponential manner that's why all bridges built at greater height will be considered wind effect

Answer 2

wind energy is unequal heating of the land mass and water bodies by solar radiation generates air movement and cause wind to blow.The kinetic energy is harnessed by windmills,to generate electricity.To generate electrycity, the rotatory motion of the windmill is used to turn the turbine of the electric generator.The output of a single windmill is quite small and cannot be used for commercial purposes.Therefore,a numberb of windmills are erected over a large area,is known as wind energy farm.
limitation
1. The initial cost of estabilshment of the farm is quite high.
2.The wind speed should be higher than
15km/h to maintain the required speed of turbine.
