E.3.2—Binding energy and mass defect question 1
[Maximum number: 1]
This question is in two parts. Part 1 is about renewable energy. Part 2 is about nuclear energy and radioactivity.
A small coastal community decides to use a wind farm consisting of five identical wind turbines to generate part of its energy. At the proposed site, the average wind speed is 8.5 m s−1 and the density of air is 1.3 kg m−3. The maximum power required from the wind farm is 0.75 MW . Each turbine has an efficiency of 30 %.

Marking guidance:
Award [0] for energy to assemble nucleus.
Do not allow "particles" or "components" for "nucleons".
Do not accept "energy that binds nucleons together" OWTTE.
