What is wind?
Wind is a form of energy, caused by differences in air pressure. Air under high pressure moves toward areas of low pressure. The greater the difference in pressure, the faster the air flows. Why does wind or air pressure matter, you may ask? It is capable of many great feats, some destructive, such as destroying buildings, cascading walls or even lifting trees from their roots in the ground.
The speed of wind is measured on the Beaufort Scale, which goes from the speed of less than 1.1 km/h, a rather slight speed, barely a breeze itself. To an outragous speed, more than 117.4 km/h, causing hurricanes, major damage to households, death, debris hurled about, etc.
Are there any advantages of wind then?
There are many advantages we can exploit from wind speeds. Wind energy has been used to our advantage since ancient times. We have been using the wind for sailing ships for the past 5500 years. The first practical windmills were used in Sistan, early in the Middle Ages. Eventually they became used by many Asian and Middle Eastern civilisations, for example "by 1000 AD, windmills were used to pump seawater for salt-making in China and Sicily". We still use the wind to sail today

In the 19th century, along with the beginning of the Industrial Revolution, we started to see even more practical purposes for windmills. We had started to provide electricity with windmills. In 1887, Professor James Blyth (a Scottishman) had begun to install his very own windmill,
