Wind power is one of the cleanest sources to get electricity. To get large scale energy from wind, wind farms are used. What can we tell about wind turbine efficiency today?
To find out how efficient wind turbines or actually wind farms are, you need to know how they work. The wind turbines accumulate the power of the wind in two steps: the propeller blades are rotated by the wind, and the propeller then drives a shaft. (more…)
