The normal use of a wind turbine is to generate electricity or to pump water. It could be used to measure wind speed but there are very inexpensive devices that do the job better.
There are 2 you could use, one being a wind sock mostly used at airports or a turbine usually used to make electricity but may also measure the force of wind.
Wind Turbine
A wind turbine is used to convert the wind into energy.
A wind turbine is used to convert the wind into energy.
Wind energy is used for electricty, wind turbine, windmills, and a wind machine
A wind turbine makes wind for scientific study.
A windmill is a type of turbine that is used to capture the energy of moving air.
Wind turbine generators are used to convert the kinetic (movement) energy of the wind directly into electrical energy, which is used to power electrical appliances and needs no further conversion.
Because...
a wind turbine generates electricity for or use
The tool that is used to create wind energy is called a wind turbine.
A wind turbine is like a giant fan that produces energy from the wind
