求翻译：風能是因空氣流動而產生的一種可利用的能量。空氣流具有的動能稱風能。空氣流速越高，它的動能越大。用風車可以把風的動能轉化為的有用的機械能；而用風力發動機可以把風的動能轉化爲有用的電力，方法是透過傳動軸，將轉子（由以空氣動力推動的扇葉組成）的旋轉動力傳送至發電機。到2008年為止，全世界以風力產生的電力約有 94.1 百萬千瓦，供應的電力已超過全世界用量的1%。風能雖然對大多數國家而言還不是主要的能源，但在1999年到2005年之間已經成長了四倍以上是什么意思？

Wind energy is the energy available due to an air flow generated .

Wind energy is as a result of air flow of a available energy. The flow of air of kinetic energy said wind. The higher air flow, and its kinetic energy. With windmill can on the lookout kinetic energy into the useful mechanical energy; and wind engine can on the lookout kinetic energy conversion s us

風能是因空氣流動而產生的一種可利用的能量。The air current has the kinetic energy calls the wind energy.The air speed of flow is higher, its kinetic energy is bigger.The kinetic energy may act as lookout which with the windmill transforms as the useful mechanical energy; But the kinetic energy which may act as lookout wi

Wind power is a result of air flow in a usable energy. Air flow kinetic energy of wind power. Higher air velocity, its kinetic energy is larger. With windmills wind's kinetic energy into useful mechanical energy can, but wind turbines wind's kinetic energy into useful electricity, either via the dri
