How do Wind Turbines work ?

Help us to make future videos for you. Make LE’s efforts sustainable. Please support us at !

Working of a wind turbine is illustrated in this video with the help of animation. The topic covered are blade design, use of brake, velocity sensor, yawing mechanism, blade tilting, wind turbine efficiency and Betz’s limit.

  1. Imagine that you are a traditional electrical energy producer. You are in the hydroelectric, gas, coal, or oil electrical generation business. And along comes something called "WInd Turbines". For a relatively small investment, wind turbines are supposed to produce electricity very cheaply. So how do you fight this? You design a "Wind Turbine", which is expensive to build, and produces very little electricity. The "design" you come up with is only actually designed to do one thing, and that is to lose money! Without a government subsidy, wind turbines never make enough money to pay for themselves, and never create a profit. Even WITH the free government subsidy money, the scheme still loses money. The goal here is to discourage clean energy production, and have environmentalists pay for it.

  2. I am an Arab inventor living in Turkey and a graduate of electrical engineering. I was late in inventing an air turbine to produce energy and turned it to work without air, which works for me in my house and I need to deliver my voice to the whole world. The turbine gives 15KVA and I use it in my house and have a month and a half without interruption to contact me personally 00905327264909

  3. the kinetic energy is better because it does not produce polluting residues like the wind energy that when using different oils contaminate more in their malfunctions

  4. Very informative video. I would love to see a follow up on the subject. Explain what Infrasound is and why engineers are scrambling to address the low frequency sounds
    omitted by the wind mills. (Sound dampeners etc.)

  5. Wind turbines are just the nicest things ever. They spin round all day without a care in the world and help us with everyday things. And people have the nerve to call them eyesores? The people of this planet…

  6. There’s a lot of broad notions being put out in this video. The truth is all of this stuff is way above any person that came to this video’s pay rate. There’s no way any one of us could develop something so complex and so technologically efficient both in software and hardware even if we studied for the rest of our lives. This kind of technology is the product of hundreds or thousands of years of advancement in science.
