What type of thing is wind energy? Wind Energy - Sun heats up uneven surface of earth,which causes motion of air. Hot air and cold air interchanges their places lead to flow of air. As it has force with motion, It carries kinetic energy.
Britannica Editors - September 20, Humans have used wind as a source of energy since the invention of sailing craft and windmills.
Modern wind turbines generally consist of a rotor with three blades; a nacelle, which typically contains a gear box, generator, brake, yaw motor, and yaw drive; and an anemometer. As the wind pushes the blades, power is transferred from the rotor to the gear box and generator and is eventually deposited into an electrical grid, which then distributes power to consumers.
The efficiency with which a wind turbine is able to capture wind power and transfer it to a grid depends on several design elements. For example, rotor blades can be built with a subtle twist, which allows for maximum wind power capture.
Other elements, such as a large generator and large-diameter rotor, enable the capture of large amounts of energy but also have higher energy costs than turbines that use smaller rotors and generators. Site selection in itself presents many challenges for wind farm development. Wind farms are most cost-effective in areas with consistent strong winds; however, these areas are not necessarily near large population centres.
Thus, power lines and other components of electrical distribution systems must have the capacity to transmit this electricity to consumers.
Wind farms have become commonplace in countries such as the United States, Canada, and Australia and are found in many countries in Europe. They have even been built in such remote locations as Ross Island in Antarctica.
With wind turbines, the farm is capable of producing more than megawatts of energy. This is more than most coal plants average; about megawatts of energy are generated by the typical coal-fired plant.
Developed by BPFowler Ridge is expected to generate about megawatts of energy, enough to provide power for somehouseholds. So far, turbines, with a production capacity of megawatts are up and running.
According to the U.
The global leader in wind power is Denmark, with nearly 20 percent of its power being derived from wind energy.

The Cape Wind Project is a proposed wind-turbine project off the shoreline of Cape Cod in Massachusetts. This sample essay on energy articulates how wind power can be used as a sustainable source of energy to help conserve the earth’s natural resources. The power of wind Wind is created by the rotation of the earth and the solar energy of the sun heating up the Earth’s atmosphere unevenly.3/5(7).

Another type of anemometer uses pitot tubes that take advantage of the pressure differential between an inner tube and an outer tube that is exposed to the wind to determine the dynamic pressure, which is then used to compute the wind speed.
