The energy in the wind turns blades around a rotor, and the rotor is connected to the main shaft, which makes a generator turn to create electricity. The shape of the blade causes the air pressure to be uneven, higher on one side and lower on the other side. And that’s what makes it spin. On the top, there’s a weather vane that’s connected to a computer to keep the turbine turned into the wind so it captures the most energy. The blades are attached to a rotor which only turns about 18 revolutions a minute and that’s not fast enough to generate electricity by itself. So, the rotor spins a series of gears that increases the rotation up to 1800 revolutions per minute. At that speed the generator can begin to produce electricity. The windmills are tall, because the higher you go, the winder it is. The blades can sweep circle in the sky longer than a football field. A windmill can power up to 9,000 homes Oceans and the Great Lakes provide consistent source of wind that we can capture and turn into electricity. The wind turbine works opposite of a fan. Wind turbines use wind to make electricity instead of using electricity to make wind. The wind turbines convert the kinetic energy in the wind into mechanical power. There are two types of windmills horizontal-axis and the vertical-axis. Horizontal-axis windmills have two or three blades. The vertical-axis windmills main rotor shaft is set traversed and the main components are located at the base of the turbine. This arrangement allows the generator to be easy facilitating service and repair. The…
