Wind power, how it works and how it’s used
Wind is the movement of air caused by difference in atmospheric pressures. Wind comes to many different uses along with many benefits; one of its greatest benefits is that it’s a renewable source of energy unlike materials such as coal and oil. The use of wind for energy also does not have as much of a negative impact again like fossil fuels as wind does not let of any harmful substances to the environment. One way in which we use the wind for creating electricity is by wind turbines. These are large towers built with propellers at the top, these propellers are also known as blades. When the wind is spinning these blades, they turn the rotor which then turns the generator. This is kinetic energy which is then converted into electrical energy. Many of these turbines are built in multiples to create a wind farm, they supply power on a larger scale for larger cities which are only built in places with a lot of strong winds. The main purpose is to capture as much wind as possible in order to create as much electricity as possible.
Another couple of advantages is that the land underneath can also be used for farming and wind farms can also be great tourist attractions too as they can look attractive depending on where it is. (1) (2)
Although wind turbines have many pros, they also come with cons. One of the main ones is that wind is not predictable. The production of electricity all depends on how much wind is there is, one day there could be lots of wind therefore lots of electricity, but you could get another day where there is very little wind therefore very little electricity, so electricity produced cannot be predicted. Suitable areas for wind farms to be built is by coasts because this is where there is the most wind but land near the coast can be
