How Does Wind Power Work?

People are now into building their own wind turbines in the hope of cutting costs on their daily expenses on electricity. These mechanisms are indeed very helpful, and knowing how they do their job would be quite advantageous, as well. Listed below is vital information on how does wind power work:

• Wind power is generated through the capture of the wind's motion. The kinetic energy in the wind's movement serves as the force to run a turbine that creates the electricity - basically, the process involves turning kinetic energy into mechanical energy.

In essence, wind movement is greatly influenced by the interaction between hot and cold air in the environment.

In a particular area where the environment becomes hot due to the sun, hot air accumulates and eventually rises as it becomes lighter. And because the movement of the hot air causes a vacuum in its original place, it creates pressure, which sucks in cooler air.

Thus the rush of this cool air is what creates the force of the wind.

• By placing a wind turbine in the path of the wind, energy within can be converted into electricity.

The wind passes through the turbine’s rotor blades where the energy is converted. The energy spins a rotor inside a generator to convert the energy into electricity.

Once converted, the electricity is then connected to cables in the turbine, down to other turbines to generate the maximum power it can produce before it is fed into an electricity system.

• Wind turbine output depends on how fast the wind is blowing so the general rule of thumb is, “the greater the wind speed, the more electrical energy generated” - when putting up a wind farm.

In windy areas, a substantial amount of wind force would be enough to run a large track of land purposely erected with wind-capturing equipment designed to generate electricity.

A general rule on how does wind power work is that the wind speed must be at least 10 mph (16 km/h or 4.5 m/s) in order to become a viable source of electricity.

• Increasing the altitude of the turbine to that of the landscape increases the chances of collecting wind energy by 10 percent and thus results in a greater power generation by 34 percent.

The wind blows faster at higher altitudes, so an area’s topography, surface roughness, and upwind obstacles like trees and buildings affect the wind’s speed.

There is also a followed rule in tapping wind energy. Wind's power varies in different places, in which states where wind speed rises is proportional to the increase of altitude.

It is said that global wind power is much greater than the present energy consumption of the world. This assumption on how does wind power work takes into account an average annual wind speed of 6.9 m/s at 80 m; at 6 turbines per square kilometer, for 77m diameter running; with a capacity of 1.5 MW per turbines planted on roughly 13 percent of the global land area.
