风很早就被人们利用--主要是通过风车来抽水、磨面……。人们感兴趣的，首先是如何利用风来发电。风是一种潜力很大的新能源，人们也许还记得，十八世纪初，横扫英法两国的一次狂暴大风，吹毁了四百座风力磨坊、八百座房屋、一百座教堂、四百多条帆船，并有数千人受到伤害，二十五万株大树连根拔起。仅就拔树一事而论，风在数秒钟内就发出了一千万马力(即750万千瓦；一马力等于0．75千瓦)的功率!有人估计过，地球上可用来发电的风力资源约有100亿千瓦，几乎是全世界水力发电量的10倍。全世界每年燃烧煤所获得的能量，只有风力在一年内所提供能量的三分之一。因此，国内外都很重视利用风力来发电，开发新能源。
The wind was used by people for a long time-mainly through windmills to pump water and grind the surface... People are interested in how to use wind to generate electricity.Wind is a new energy source with great potential. People may still remember that in the early eighteenth century, a violent wind swept across Britain and France destroyed 400 wind mills, 800 houses, 100 churches, and 4 More than a hundred sailing ships, thousands of people were injured, 250,000 big trees were uprooted. As far as pulling trees is concerned, the wind can emit 10 million horsepower (that is, 7.5 million kilowatts; one horsepower is equal to 0.75 kilowatts) in a few seconds! Someone has estimated that the amount of wind resources available for power generation on the earth is about There are 10 billion kilowatts, almost 10 times the world's hydroelectric power generation. The energy obtained by burning coal every year in the world is only one third of the energy provided by wind power in a year. Theref

There are many applications of electricity in life. The first is lighting. Second, cooking. The computer we use also uses electricity. In order to save energy and use electricity, we go out and turn off the lights. We can use solar energy to generate electricity. It's more energy efficient.
