人类对风力的利用有着悠久的历史,公元前一千多年前就已利用风力制粉磨面、提水灌溉等。在欧洲,从十四世纪到蒸气机取代风车的十九世纪为止,风车与水车一样是不可缺少的动力机。十九世纪,美国在其中部和西部新开发的地区建造了六百余万台多翼型风车,主要用于扬水。 风力是非常巨大的能源,且不会污染环境;但由于其密度小、速度和方向变化不定 The use of wind power by humans has a long history. Before millennium BC, wind power milling and water extraction were used. In Europe, from the XXI century to the 19th century when steam engines replaced windmills, windmills were as essential as watermills. In the nineteenth century, the United States built more than six million multi-wing windmills in the newly developed areas in the central and western regions, mainly for water lifts. Wind power is a very large energy source and does not pollute the environment; however, due to its low density, variable speed and direction
