How do wind turbines make electricity?
You've seen them spinning on hilltops — those giant white towers with three enormous blades slicing through the sky. Wind turbines. They stand there like patient giants, waiting for the breeze. But here's the wild part: inside each one, invisible air is being turned into electricity. Actual power. The kind that charges phones and runs refrigerators and lights up cities. How does wind — which you can't even see — become something you can plug into?
It starts with the blades. When wind hits them, it pushes. The blades are shaped like airplane wings — curved on one side, flatter on the other. That curve makes the air move faster over the top, creating lower pressure there, which pulls the blade forward. It's the same trick that lifts a plane into the sky, except here it spins the blade around instead.
