In the third unit of our Design and Engineering course, our project as action was to design, construct, and test a wind turbine.  We did this in order to learn about the sustainability of wind energy. To find the efficiency of wind turbines, we calculated the cost and energy produced by a turbine in comparison to a solar panel. We found that the wind turbine was initially more expensive, but produced more energy and saved more money over time. After speaking to the CEO of Windonics and watching videos of different wind turbine designs, we set out to build our own. Below is a presentation of the steps we took and the results of the design.
