00:00Humans have harnessed wind power for centuries, from sailing ships to windmills.

00:04Today's wind turbines are a modern evolution of those early designs.

00:09These massive machines capture wind energy and convert it into electricity.

00:14Let's explore how they work.

00:16A wind turbine converts wind's kinetic energy into mechanical energy, and

00:20then into electricity.

00:22It starts with the blades, which are shaped to catch the wind.

00:26The wind's force causes the blades to spin.

00:29The blades have an airfoil shape, splitting the wind into two streams.

00:33The air moving over the top of the blade travels faster and

00:36creates lower pressure, while the air underneath travels slower and

00:40creates higher pressure.

00:42This difference generates lift, spinning the blades like an airplane wing.

00:47The blades are attached to a rotor that spins with them.

00:51This motion is transferred to a low-speed shaft, which leads to the nacelle,

00:56a casing housing the gearbox, generator, and controls.

01:00Inside the gearbox, a low-speed gear connects to the low-speed shaft.

01:05The blades typically spin at 15 to 40 RPM, too slow for generating electricity.

01:12The gearbox includes a high-speed gear that turns faster,

01:15from 1,000 to 1,800 RPM, increasing the speed for the generator.

01:22This high-speed gear transfers rotational motion to the generator,

01:27which converts it into electricity using magnets and coils.

01:31The electricity is then sent to a step-up transformer via a power cable in

01:35the turbine.

01:37The transformer boosts the voltage before it's integrated into the power grid.

01:42Sensors on the turbine monitor wind conditions,

01:45allowing the controller to adjust the turbine's orientation and

01:48blade angles for optimal performance.

01:51In strong winds, the controller engages the brakes to protect the turbine.

01:56Blade pitch mechanisms adjust the angle of the blades to handle different

02:00wind speeds efficiently.

02:02Wind turbines showcase the ingenuity of modern engineering,

02:06converting wind into clean, renewable energy.

02:09Understanding their operation highlights the blend of science and

02:13technology behind this sustainable power source.
