The role of a wind turbine is to take the kinetic energy created from moving air (i.e. wind) and turn it into electricity. In other words, it transfers energy from one form of medium, to another.
How does it work?
- A wind turbine consists of 2-3 peller-like blades around a rotor.
- The rotor is connected to a shaft that leads from the hub of the rotor to a generator.
- When the turbine blades capture wind, they cause the shaft to spin.
- The generator takes the rotational energy and turns it into electricity.
- In order to capture the most energy, the turbines are mounted on towers that reach 100 feet or more above the ground.
- The higher altitude creates an environment with faster and less turbulent wind.
