An odd number is always preferred. This decreases off axis torque on the shaft as the lower most blade aligns with the tower. Three is typical for industrial turbines, I believe it's a weight / combined blade length ratio. Smaller home turbines may have many blades and an annulus (to limit tip losses) for higher power densities.

How does a wind farm collect energy?
Wind moves the blades of the wind turbines. The turbines turn an electrical generator, which feeds electricity into the network of powerlines.
Why do wind turbines spin?
Because the wind moves the blades witch causes the turban to go
Do wind turbines make a sound?
Wind turbines are designed to be quiet but all make a sound when the blades are being driven. There is an amount of noise caused by the generating equipment and there is the noise of air turbulence as it passes the blades.
What are those things that spin around called on the wind turbines?
Rotors or blades.
How is electricity produced by wind energy?
The wind spins the blades which are connected to turbines which cause the turbines to spin and create electricity that is spread across a power grid.
How many blades do most wind turbines have?
There are 3 blades3 blades on each turbine
Do wind turbines use electricity to start turning?
No. Wind blows the blades, and the pole attached to the blades is attached to the turbines, which physically turns the turbines, and the movement of the turbines create electricity.
Why does wind turbines have long blades when short blades go faster?
Long Blades Catch More Wind Then Short Blades
What is the ideal number of blades on the wind turbines?
Three
What are the advantages of generating electricity by wind turbines compared with generating it at an oil-fired power station?
wind turbines have blades like the propellors on the first aeroplanes wind turbines with blades convert 20-30% of wind energy into electricity but this new turbine can convert 70%.
What are wind towers and what is its use?
Wind towers uses the power of the wind to propel the blades of the turbines. The turbines cause the rotation of magnets, which creates energies.
How does a wind farm collect energy?
Wind moves the blades of the wind turbines. The turbines turn an electrical generator, which feeds electricity into the network of powerlines.
What has to be built for wind energy to be used?
Wind Turbines. They have a motor inside of them that produces energy when the blades of the turbine turn and when they turn energy is generated by the wind turning the blades and the motor. <><><> In addition to the wind turbines, you need a grid of powerlines to carry the electricity to where it will be used. This frequently costs more than the wind turbines.
Why are wind turbines three bladed when more blades should catch more wind?
the reason there is only three blades is because four blades would add weight and wind resistance, in some countries they use two or four bladed turbines though. \
What are the white fans that make electricity called?
The white fans that make electricity are called wind turbines. Wind turbines are devices that convert the kinetic energy of the wind into electrical energy through the use of rotating blades. When the wind blows, it causes the blades to spin, which in turn drives a generator to produce electricity. Wind turbines are commonly used to generate renewable energy from wind power.
