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.
Wind 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
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.
Windmills are built in flat open areas
Wind turbines have an emergency shut off in case of a wind storm or tornado
Windmills have been around for 5,000 years
A wind farm is a place where there are many windmills together in one location and they all work together to create electricity
Why is wind power better?
It’s often one of the least expensive forms of renewable power available
