How Windmills Work?
The windmill's blades are turned by the wind that passes Over the windmill.
Wind Converted to Electricity
To convert wind to electricity, the blades of a wind turbine turn into a shaft which is attached to a gear
transmission box. That transmission box increases the turning speed in the shaft which connects to the generator that
creates electricity.
In ShortWind turbines convert the kinetic energy in the wind into mechanical
power

What Do Windmills look
like?Modern windmills are usually tall, skinny,
and made of aluminum or steel. Most have two or three blades.
On most windmills the blades make a 150 foot circle
Windmill Models The traditional windmill
uses a horizontal axis. They are also the most
common type of windmill used.
There are other types of windmills which use a
vertical axis that looks a lot like an egg beater.
These are less commonly used.

Why is wind power better?
• Renewable resource• It’s often one of the least
expensive forms of renewable power available • It’s clean
