 Roughness and Wind Shear |
|
No, look at the two chimneys. The wind is strongest at the top of the tall chimney.At the ground it is not as windy as just 40–70 metres higher up.The stronger the wind is, the more energy is in it.That is why the rotor should be as high in the sky as possible to make the wind turbine generate more power. |
| Yes, you are right. 40-70 metres up in the sky it is a lot windier than down by the ground.You can tell by the smoke from the chimneys.The higher up the rotor is, the more power is generated by the wind turbine. |
| What Do You Think ?
Obviously the tower has to carry the nacelle and the rotor, but does it have to be very tall ? What do you think ? |
