How Much Power Does a Wind Turbine Generate? Sciencing

Apr 24, 2018 · Efficiency is an important value to know when assessing a wind turbine. In an ideal world, a turbine would convert 100 percent of wind passing through the blades into power. Because of factors such as friction, these machines only have efficiency ratings of between 30 percent and 50 percent of rated power output.

Windmill Efficiency.

Efficiency is important for windmills, because the entire cost is in the technology, not the source of energy, which is wind. The most significant factor determining the efficiency of windmills is the number of blades. This is because more blades capture more energy. Large windmills must use few blades due to stress on the metal.
