Wind's Power Dance
How does a wind turbine make electricity?
You've seen them standing tall on hillsides and out at sea — those enormous white towers with three giant blades slowly turning in the wind. They look almost elegant, like they're dancing. But inside each one, something brilliant is happening: they're catching invisible air and turning it into electricity that powers your home.
It all starts with the wind — moving air that's rushing past because the sun heated up one patch of Earth more than another. When that moving air hits the turbine's blades, it pushes them, just like wind pushes a sailboat forward or spins a pinwheel in your hand. The blades are shaped like airplane wings, curved on one side and flatter on the other, so the wind doesn't just bump into them — it pulls them around.
