It is because it stays as long as the sun shines. We can use it as wind turbines, windmills, wind pumps, wind farms, and wind panels!( the wind panel was recently created)
Wind, water, animal, and mechanical
Before humans used electrical motors to operate pumps to pump water from the ground, the pumps were mechanically operated, via hand (hand pumps), wind (windmill pumps), etc.
I doubt that a uniform count of windmills is available. Also, do you include wind pumps and wind turbines?
due to the flow of wind, the wind turbine rotates, which will be coupled to the shaft of the alternator(generator) through gear mechanism

You can use wind energy for running energy around the house!!!!!!
The wind catches the sales which are forced around. Windmills have a mechanism that when it turned by the miller the sales turn more in to the wind and less as required to regulate the turning speed.
Sailing boats, kites, washing lines and windmills have been around for a long time!
heat transfer through convection.
Most are electric motors.
Farmers used wind energy, the wind mills also pumped water as their blades swung.
