Wind pushes the blades
Wind is moving air. When it blows on the turbine's giant blades, it pushes them around, like blowing on a pinwheel. 🌬️
🌬️ Spin the Turbine! play
Slide the wind speed and watch what the turbine does.
🌦️ Weather and Wind Power
Where wind comes from
The sun warms some places more than others. Warm air rises and cooler air rushes in to fill the space. That rushing air is wind!
Windy at sea
Wind blows stronger and steadier over the ocean, with nothing in the way. That's why some wind farms are built out at sea.
Storms
In very strong storm winds, turbines put on their brakes and turn their blades sideways to stay safe. They start again when the storm passes.
High up
Wind is faster high above the ground, where trees and buildings can't slow it down. That's why turbines are so tall!

Wind detective
Tie a ribbon to a stick and take it outside. Which way does the wind blow it? Try it on different days and compare.
Cup wind meter
