Windmill, device for tapping the energy of the wind
by means of sails mounted on a rotating shaft.
Earlier windmills usually were used to mill grain (gristmills), pump water (windpumps)
The majority of modern windmills take the form of wind turbines used to generate electricity, or windpumps used to pump water, either for land drainage or to extract groundwater.
There are currently two different kinds of wind turbines in use, the Horizontal Axis Wind Turbines
(HAWT) or the Vertical Axis Wind Turbines (VAWT).
HAWT are the most common wind turbines, displaying the propeller or ‘fan-style’ blades, and VAWT are usually in an ‘egg-beater’ style.
Offshore wind turbines are larger, can generate more power, as the large components can be transported on ships instead of on roads.
Single small turbines below 100 kilowatts are used for homes, telecommunications dishes, or water pumping.
The electricity generated by harnessing the wind’s
mechanical energy must go through a transformer in order increase its
voltage and make it successfully transfer across long distances.
Power stations and fuse boxes receive the current and then transform it to a lower voltage that can be safely used by business and homes.

A windmill is a mill that converts the energy of wind into rotational energy by means of vanes called sails or blades.

How Does a Wind Turbine Generate Electricity.....
Wind power converts the kinetic energy in wind to
generate electricity or mechanical power.
This is done by using a large wind turbine usually consisting of propellers; the turbine can be connected to a generator to generate electricity
As the wind passes the turbines it moves the blades, which spins the shaft.
To create electricity from wind the shaft of the turbine must be connected to a generator.
The generator uses the turning motion of the shaft to rotate a rotor which has oppositely charge magnets and is surrounded by copper wire loops.
Electromagnetic induction is created by the rotor spinning around the inside of the core, generating electricity.
Utility-scale turbines range in size from 100 kilowatts to as large
as several megawatts. Larger wind turbines are more cost effective and
are grouped together into wind farms, which provide bulk power to the electrical grid.This is done by using a large wind turbine usually consisting of propellers; the turbine can be connected to a generator to generate electricity
