The Prospect of Wind Power Generation
As the traditional energy, such as fossil energy, getting less and less, Current Energy Issues get increasingly attention now. In consequence, the development of new energy becomes more and more urgent. We know, because of the difficulties of technology and the potential danger of the nuclear power, nuclear power is not adapted to most places, what’s more, it requires a lot on resource, which can hardly be massively collected on the earth. Therefore, it cannot be well developed currently. And as for hydrogen power, its preparation is not easy as well. Now human being has not found a proper way to create hydrogen depends on low energy and of easy raw materials. So to conclude, there massive new energy resources, but most of them are too regional that cannot be widely applied; or too assuming on cost, which are the barriers of its application. So now we turn to a kind of clean energy which has a positive prospect—Wind Power Generation, which is to change the easy-got and clean primary energy to a secondary energy resources—electricity, which is very convenient to transportation and application. It had been used to draw water for irrigation or mill flour. But now, it will be used for the public.
The advantages of wind power generation are listed as following: 1. Its containing quantity is marvelous. The global wind power is approximately 2.74×109MW, of which 2×107MW is available. Which is more than ten times larger the total usable hydropower. 2. The resource spreads very widely so that it will not rely on some particular region like hydropower which must be built by a 3. As a clean renewable energy resource, when it is used, there will be no any pollution to our environment and it won’t die away before the sun. It is easy to understand, because what it use to create electricity is wind: after the fans driven by wind are speed up by the booster engine, the mechanic energy will be translated to electricity by electric generators. Therefore, no pollution has been produced. 4. The devices needed are very flexible, so that they can be assembled more easily, timesaving, and cost-efficient as well. What is used to develop wind power is called wind generating set, which consists of wind turbines(including tail rudder), electric generator and pylon, all of which are easy to produce and assemble.
5. In recent time, either in the world or our territory, the development of wind energy is very fast, which means the basement of the technology is generally built, the massive application is on ahead. As a matter of fact, there actually are some disadvantages about the new energy. Such as much occupation on the room, a little noise, and instability as well. But when taking the large territory and plentiful wind power into account, despite of these negative dimensions, it’s still very feasible to development this kind of new power.
As the worldwide environment getting worse and worse as a result of human being’s activities, now it’s our time to develop a more environmentally-friendly way to get our necessary everyday energy. To solve the energy problem and keep a clean world as well, wind power resource is a proper solution we could adopt.

风力发电的原理，是利用风力带动风车叶片旋转，再透过增速机将旋转的速度提升，来促使发电机发电。依据目前的风车技术，大约是每秒三公尺的微风速度（微风的程度），便可以开始发电。
风力发电正在世界上形成一股热潮，为风力发电没有燃料问题，也不会产生辐射或空气污染。
风力发电在芬兰、丹麦等国家很流行；我国也在西部地区大力提倡。小型风力发电系统效率很高，但它不是只由一个发电机头组成的，而是一个有一定科技含量的小系统：风力发电机＋充电器＋数字逆变器。风力发电机由机头、转体、尾翼、叶片组成。每一部分都很重要，各部分功能为：叶片用来接受风力并通过机头转为电能；尾翼使叶片始终对着来风的方向从而获得最大的风能；转体能使机头灵活地转动以实现尾翼调整方向的功能；机头的转子是永磁体，定子绕组切割磁力线产生电能。
风力发电机因风量不稳定，故其输出的是13～25V变化的交流电，须经充电器整流，再对蓄电瓶充电，使风力发电机产生的电能变成化学能。然后用有保护电路的逆变电源，把电瓶里的化学能转变成交流220V市电，才能保证稳定使用。
通常人们认为，风力发电的功率完全由风力发电机的功率决定，总想选购大一点的风力发电机，而这是不正确的。目前的风力发电机只是给电瓶充电，而由电瓶把电能贮存起来，人们最终使用电功率的大小与电瓶大小有更密切的关系。功率的大小更主要取决于风量的大小，而不仅是机头功率的大小。在内地，小的风力发电机会比大的更合适。因为它更容易被小风量带动而发电，持续不断的小风，会比一时狂风更能供给较大的能量。当无风时人们还可以正常使用风力带来的电能，也就是说一台200W风力发电机也可以通过大电瓶与逆变器的配合使用，获得500W甚至1000W乃至更大的功率出。
使用风力发电机，就是源源不断地把风能变成我们家庭使用的标准市电，其节约的程度是明显的，一个家庭一年的用电只需20元电瓶液的代价。而现在的风力发电机比几年前的性能有很大改进，以前只是在少数边远地区使用，风力发电机接一个15W的灯泡直接用电，一明一暗并会经常损坏灯泡。而现在由于技术进步，采用先进的充电器、逆变器，风力发电成为有一定科技含量的小系统，并能在一定条件下代替正常的市电。山区可以借此系统做一个常年不花钱的路灯；高速公路可用它做夜晚的路标灯；山区的孩子可以在日光灯下晚自习；城市小高层楼顶也可用风力电机，这不但节约而且是真正绿色电源。家庭用风力发电机，不但可以防止停电，而且还能增加生活情趣。在旅游景区、边防、学校、部队乃至落后的山区，风力发电机正在成为人们的采购热点。无线电爱好者可用自己的技术在风力发电方面为山区人民服务，使人们看电视及照明用电与城市同步，也能使自己劳动致富。

    风产生了能量并且被我们转化为电力从而方便我们的生活并且不会造成污染。地球已经危在旦夕，科学家表明各种能源将在近年内被人类消耗完毕。随着地球人口的增长，人类的需求也愈来愈多，如同贪食的饿狼一般汲取着地球的资源。所以，我们想出了各种方法节省能源，风能，地热能，潮汐能等等。由于各种可被燃烧的材料产生温室效应，如同我们的母亲，地球，正在被污染一点一点的侵蚀着。风是通过太阳的热力，通过不同的地点散播到各地。风能被标定为可循环能源是因为风是用之不竭的能源。

    风力发电机一般都会放置在海岸或者风力很强并且很稳定的地方, 为了能让风得到更好的利用，一般强风都会在海岸线所以说才会建在海岸线旁，或者说那些建筑在开放的地方都是拥有着强风并且土地非常宽阔。像我们平时生活在城市里的风，虽然有时候非常强，但是也同时要注意“有时候”所以说不稳定的风能不能使风力发电器运作，就如同只喝了一口水的鸟儿要求它没日没夜的飞也是不可能的。更何况，像城市这样拥挤的地方，别说是风力农场了，就连一个放不放得下都是个问题呢。

    风会把像刀片一样的转子转起来，大部分的装置都是三片叶子的，基本都没有四片的转子，转子的形状像细长的菱形。转子会转动然后传到发电器，把风能转换为电能然后供我们使用。现在，我们来讲风能的利吧。因为风能是可循环使用的能源，所以是对环境非常有利的。再者，据专家估测，全球可利用的资源有200亿千瓦，是可利用水力的资源10倍，而我国的资源约16亿千瓦，所以是一个十分可观的数字。并且，经过科技的发展，风力发电的技术水平越来越高，而成本越来越低。同时，对人类愈加有利，不会造成任何污染。

    好了，现在风能的利说完了，现在来说它的弊吧。首先，风能利用的地方很少，因为它放置的地点要求非常高，必须大并且风要量足。其次，风力发电器还煞风景并且影响人们的生活，非常吵闹。再次，经过这次的室外探查，风能发电器并没有对我们的生活造成很大的影响，但是它需要占据非常多的土地去产生一个风能农场。虽然风能发电器可以建造在海上，但是它的坏处是不能对它进行准确的控制，并且及时停止它的运作。最后，风能需要人工的多加照顾，不能“骂”，不能“打”。风如果太大的话，机器会烧掉并且需要重建，并且，风能发电器还很贵。如果风太小了，它就会停下来，不能产生电能。

    我对风能的看法是矛盾的，首先，因为风能是可再生能源所以我希望风能能更加被利用，可是同时风能需要占据非常多的土地，随着人口的增长，地球已经容不下这么多人。更何况还要多余的土地去建造风力发电器，所以这是一大问题。
