What is wind? Most simply, wind can be defined as moving air. Although this may seem like a very basic explanation, wind is a phenomenon that can be interesting to explore because you cannot actually see it.
Wind turbines have four basic parts–a tower, blades, a gear box, and a generator–that function together to convert kinetic energy from the wind into electrical energy. As the blades turn, they cause the gear box to turn, via a shaft. The turning gear box causes the generator to turn via a second shaft. The turning of the generator generates electricity.
The amount of electricity that can be generated by a wind turbine is affected by many variables. In this experiment, you will explore variables that affect how a turbine turns. You will then investigate the effect of fan speed on the power output of a wind turbine.
