Windmills use blades to gather wind that flows over it. Just like an airplane uses wings for lift, windmills use their blades for lift as well - in this case to turn the windmill. Windmills are pretty simple structures; their blades are connected to a drive shaft that is connected to an electric generator. As the blades turn, this turns the drive shaft and creates electricity. Electricity is sent through wires and collected.
There are several different types of windmills, categorized by the direction in which their blades rotate. Two different types of windmills, most commonly called turbines when producing energy, are the horizontal axis turbines and the vertical axis turbines. Horizontal turbines are by far the most popular type of turbine and are the traditional type of windmill with blades that are similar to an airplane's propeller. These are the windmills we often see pictures of - the Holland variety. On the other hand, vertical axis windmills have blades that resemble an egg beater. They are far less popular than horizontal windmills only making up a very small overall percentage.
In addition, wind mills can be used to harness energy without producing electricity. An example is the type of windmill that takes the mechanical motion induced by the blades to turn millstones that grind corn and other grains, hence the term "windmill". Other examples of non-electrical windmills include those that pump water. (These have been around for a long time.)

What work do wind mills do?
In the olden days, wind mills used to churn butter.
What is the difference between wind mill and wind turbine?
Wind mills are mechanical devices that uses that power to do work. Wind turbines are electromechanical devices to work for us by making electricty.
How is wind energy derived?
Wind energy is derived from wind mills. These wind mills are powered by the wind and capture it's energy when it blows.
What force is used when winds mills move?
wind mills => wind power (eolian energy).
What are 5 examples of wind energy?
-Wind Turbines-Wind Mills

Are wind mills renewable or non-renewable?
The turbines (mills) themselves are non-renewable but the wind the power source that is converted into useful work (usually electricity) is renewable.
What is the difference between wind mill and wind turbine?
Wind mills are mechanical devices that uses that power to do work. Wind turbines are electromechanical devices to work for us by making electricty.
What can wind mill power?
Wind mills have traditionally been used to power grain mills, saw mills, and small manufacturing mills. A wind mill can also be used as a wind turbine, to generate electricity.

How is wind energy transferred?
Wind energy is transferred by wind mills.
How is wind used directly?
For examples in wind turbines or wind mills.
