The earliest known windmills were in Persia (Iran) and looked like large paddle wheels.
Today, the largest wind turbines in the world have blades longer than a football field.
One wind turbine can provide enough electricity for about 300 homes.
The atmosphere moves the earth's temperatures from one place to another creating wind.
When winds blow really hard they're called: hurricanes, tornadoes, microbursts, zephyrs, sirocco, sharav, mistral or monsoons.

Comment: Do we get these in SA? Maybe Telkom should build a few of these so we wouldn't get all the power outages.

Comment: Kdog is right, but they seems to be dangerous as well. Rather be away from communities.
