Wind Power


“Wind” refers to flow of gases from high-pressure area to low-pressure area. Wind originates from the differential heating on the surface of the Earth. When hot air ascends, cold air will fill in the place and result in flow of wind.

Wind has been a source of power for mankind before the popularization of electricity. In ancient times, sailors raised sails to draw power from the wind; farmers used windmill to grind cereal and pump water. Today, more and more wind turbines are being installed on the land and at the sea to generate energy with wind.

A wind turbine is comprised of hub, rotor, wind vane and blades. A turbine tower can be 60-floor high from sea level with a swept area with diameter of 160 meter long.

The principle behind the wind turbine is to have wind drives the three-blade rotor and convert the kinetic energy of the wind into electrical energy; the wind vane will direct the turbine to always face the windward side to receive the maximum speed of the wind. Both onshore and offshore wind farm is comprised of numbers of independent wind turbines connected to the electricity grid and eventually the users.

Using Wind Energy

Wind is often described as characteristic, unpredictable and hard to control. However, wind power is a type of renewable energy with no pollution to the air and water. Although wind power is an intermittent resource, one can prepare the production and the grid for the upcoming changes in accordance with the weather forecasts.

Thanks to the massive production and the improvement of technology which drives the reduction in costs of materials and construction, the production capacity of wind power has been surging.
