Power obtained by harnessing the energy of the wind is called wind power.
How its created: Wind power or energy is created by natures naturally occurring wind.
How it works: Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.
Cost to install: A wind turbine costs approximately $48,000 - 65,000 to install. The equipment cost is about
$40,000 and the rest is shipping and installation.
Pros and cons:
Pros: Wind power can almost be used anywhere, has a low-life carbon footprint, it uses clean energy, and it is renewable.
Cons: It has a localized impact on night-time temperatures and weather, some people complain of the noise from turbines, and the wind may be inconsistent at times.

Interesting facts: Wind mills date all the way back to 2000 BC, where they were used in China.
In some countries such as Denmark and Portugal, wind power contributes around 20% of the total electricity production.
Modern wind turbines usually have 3 blades which can reach speeds at the tip of over 320 kph (200 mph).
