In the weekend Emma went to the Mahinerangi Wind Farm Open Day. During news toady she presented a poster about wind turbines and told us about her visit.
Here is the information she wrote on her poster:
How does a windfarm work?Wind turbines capture energy from the wind and turns it into electricity. As the wind blows and passes across the blades of a turbine, it creates lift and slowly turns the blades. The blades are connected to a main shaft, which also spins and leads into a generator. The generator converts the rotational energy from the blades to electricity. Electricity passes through a transformer and transmission t=lines to reach the main grid where it can be transported to homes, businesses and other consumers.
Facts:
* The 12 wind turbines generate enough electricty to power 13,000 Dunedin homes.
* The turbines are 132m tall.
* A turbine blade is 44m long.
Great poster thanks Emma!
