What is a wind mill?Why do we need to establish wind energy farms?
Answers
Answer:
WIND MILL: A device used to convert Wind energy into the mechanical energy is called wind mill.
It consists of a wheel with blade cut into its outer rim. The wheel rotates about an axle mounted on a pole. The wind energy is used to rotate the wheel about its axis.
Wind mill is used for operating water pumps, grinders and is also used to produce electricity.
WIND ENERGY FARM: The electricity produced by a single windmill is very small, which cannot be used for commercial purpose. To produce electricity on a large scale, a large number of wind mils are erected in high wind energy region. The region where large number of windmills are elected to produce electricity is called wind energy farm.
Answer:
A windmill is a structure that converts wind power into rotational energy by means of vanes called sails or blades, specifically to mill grain, but the term is also extended to windpumps, wind turbines and other applications.
Wind is caused by the uneven heating of the atmosphere by the sun, variations in the earth's surface, and rotation of the earth. ... Wind turbines convert the energy in wind to electricity by rotating propeller-like blades around a rotor. The rotor turns the drive shaft, which turns an electric generator.
