Name: Joseph Stephens Date: 10/25/23 School: GSHS Facilitator: Nelson 5.05 Wind Energy Lab Part 1: Background Read Wind Turbines: the Bigger, the Better, linked on the task page. Then, answer the following questions. 1. What is hub height? Define hub height in your own words. Hub height is the distance from the ground to the middle of the turbine’s rotor. 2. Why are turbine towers becoming taller? To capture more energy since winds increase as altitudes increase. 3. What is rotor diameter? Define rotor diameter in your own words. Rotor diameter is the total width of the circle that the rotating turbine blades create. 4. What is the advantage of larger rotor diameters? Larger rotor diameters capture more wind and produce more electricity. 5. Define capacity in your own words. Capacity is the maximum power rating of wind turbines. Part 2: Research Directions: Go to the US Wind Turbine Database, linked on the task page. In the upper left corner, use the Search by Project Name search box to complete the chart for the listed projects. Start by entering a project name. Then, select the project from the results.
After you select the project, locate the project information in the list on the right side of the screen. Record the number of turbines, year online, and total rated capacity. After you find the information for the project, select the project by clicking on it. Then, your cursor over one of the turbines in the project. Record the rated capacity, hub height, and rotor diameter for an individual turbine. Finally, use the terrain map to determine if the turbines are on mountains, plains, or offshore. One sample has been completed for you.

Based on your research, how have hub height, rotor diameter, and total height of wind turbines changed over time? They have all increased over the years. 2. Based on your research, how have total rated capacity and rated capacity changed over time? Over time, total rated capacity has varied, but has increased since the start. Rated capacity has increased over time. 3. Complete the following statement: As the rotor diameter of a wind turbine increases, its rated capacity increases . 4. How has the number of wind turbines per project changed? Why do you think the number has changed? Support your answer with information from your research. It has varied throughout different projects. I think it has changed because the wind in the atmosphere is different and one location requires a different amount of energy than others.

5. Based on your research in this activity, describe the wind turbine projects of the future. Include information about the height, rotor diameter, number of turbines, capacity, and location in your answer. I think the height and rotor diameter will continue to increase in the future. I think the number of turbines and capacity will continue to vary. I think the locations of wind turbines will be determined on wind in the atmosphere and how much energy can be produced in the area.
