  1. Depends on the design of the blades, but I suspect that three is the correct answer because if you look-up pictures of ‘wind farms’ they all have 3 blades and these companies spent a lot of time and money on engineering and research to come up with their design. Remember, they are out for profit so efficiency is a top priority.

  2. electricity does not depend on the number of blabes..but only on the speed of rotation..so 3 will generate more

  3. The amount of electricity generated depends upon the wind speed.

    A carefully-designed wind turbine should (theoretically, at least) produce the maximum amount of power for a particular wind speed, whether it has 3 or 6 or any other number of blades.

    But for general application, in the usual range of wind-speeds, and considering construction costs, etc. the three-blade design has proved optimal for power production at lowest cost.

  4. 6 ; however, because they are so large the power increase is not worth the cost of the much more expensive structural considerations. The designers did not even go for 4.

How many blades will generate more electricity for Wind turbines?? 3 or 6 blades.?

thank you!!
