WIND POWER 風能

Wind power is the use of air flow through wind turbines to provide the mechanical power to turn electric generators and traditionally to do other work, like milling or pumping. Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation. The net effects on the environment are far less problematic than those of fossil fuel sources.
風能是因空氣流動而產生的一種可利用的能量,用風車可以把風的動能轉化為有用的機械能;而用風力發動機可以把風的動能轉化爲有用的電力,風力發電的環境影響遠比化石燃料發電低。

 

Wind power is the use of natural wind to initiate the rotation of windmills or wind wheels. This momentum will drive the generator to produce direct current. A current inverter can be added to transform DC to AC.

風力發電是利用空氣流動而形成的自然風轉動風車/風輪,風的動能推動發電機,因而產生直流電,並且可加一個電流轉換器將直流電轉換成交流電。
