This turning process is called yawing, and older windmills achieved it through manual monitoring. Today, wind sensors and computer systems automatically adjust the blades with expert precision to capture as much energy as possible. Outside rotor orientati...

why windmills are ugly C. the usages of the wind power D. the disadvantages of wind power 4. Which of the following is TRUE? A. People can use wind power all the time. B. Windmills used to be dangerous for birds. C. About 2.5 percent of the Denmark’s power comes from the wind....
They used to be true, but it isn't true anymore.Old windmills killed birds hecause they spun very fast. New windmills spin slowly, and they aren't dangerous for hirds One problem is that many people think windmills are very ugly. This is a problem for people.because windmills are often...
Finally, discover where windmills are located to best harness the wind. What Are Windmills? Have you ever used a fan at home when it gets too hot? It has blades that spin around to produce wind to cool you off. Well, a windmill looks similar to a fan, but it's much larger and ...
A dictionary definition explains it thus; it is a machine which is propelled by the wind from a horizontal shaft which extended onto sails. Windmills still used today, mainly in parts of the world which have traditionally relied on them, are powered by electricity or water. ...
1. B 根据短文第四段最后一句话"New windmills spin slowly, and they aren't dangerous for birds."可知,新的风车旋转得很慢,因此它们不再会杀死鸟类。故选B。2. D根据短文第二段中的“For thousands of years, people have used wind to sail boats and move water."可知,人类运用风能已不止1000年了。
Wind makes windmills spin (旋转). When the windmills spin, they make electricity. Then we can use the electricity. A lot of people think that wind power is new, but that’s not true. For thousands of years, people have used wind to sail boats and move water. We still do those ...
The basic principle of wind energy is simple. A series of sails or blades mounted around a rotor catch the wind and translate its kinetic energy into rotational energy. Traditional windmills use that rotational energy to grind wheat or pump water. But in modern windturbines, it turns a generat...
They beleve that there are problems with windpower, but many of those problems are not real. Forexample, some people say that windmills are dangerousfor birds. It used to be true, butt isnt true anymore.Old windmis illed bird because they spun ver fat.New windmils spin slowly, and they...
