vidya12 Posted April 3, 2009 Report Share Posted April 3, 2009 A wind turbine is a rotating machine which converts the kinetic energy in wind into mechanical energy. If the mechanical energy is used directly by machinery, as like a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator, wind turbine, wind power is a wonderfull way to get more high power energy It are not affected by the direction of the wind, which is useful in areas where the wind changes direction frequently and quickly. Unlike traditional horizontal axis wind turbines, a yaw mechanism is not needed to turn the wind turbine towards the wind.it are better able to harvest turbulent air flow found around buildings and other structures wind turbine are ideal for both rural and urban applications, including roof top installations. Depending on the shape of the roof, the wind flow over the roof can be concentrated, leading to an increased energy output Vertical axis wind turbines are different from traditional wind turbines in that their main axis is perpendicular to the ground. Their configuration makes them ideal for both rural and urban settings and offers the owner an opportunity to offset the rising cost of electricity and to preserve the environment. ================================================================================ ====================== Wind Turbine Solar Panel solar Cell Link to comment Share on other sites More sharing options...
EnergyChina Posted April 21, 2009 Report Share Posted April 21, 2009 wind power is a great source for green energy. And I think it really has no pollution and side effect. Link to comment Share on other sites More sharing options...
