Betz Limit
No wind turbine can capture more than 59.3% of the kinetic energy of incoming wind in an open channel. This is called the Betz limit named after the german scientist Alfred Betz who derived this limit in 1919. Betz Limit Explanation Let’s understand why the wind turbine cant extracts 100% kinetic energy from the wind….

Why are wind turbines sometimes standing still, even though the wind is blowing?
There are a number of reasons why turbines actually stop temporarily. As the name of the technology implies, wind turbines are naturally dependent on wind. Measurements of local wind conditions on site guarantee that they are built in areas with sufficient wind. There are often other reasons for turbines to be temporarily shut down. One…
How Winds are Formed?
Video: How Winds are formed? Wind results from the movement of air due to atmospheric pressure gradients. Wind flows from regions of higher pressure to regions of lower pressure. The larger the atmospheric pressure gradient, the higher the wind speed. The Sun is the key source of winds on the earth’s planet. Winds are mainly…
