(b) Collect the way you can harvest maximum energy from wind energy. (c) (4 marks) Model a wind energy system for supplying electricity to the national grid? Identify the turbine parts in the schematic diagram. (4 marks) (d) Two wind turbines have been placed side by side as shown schematically Figure 1 where the bigger wind turbine has a higher power co-efficient and the ratio is 5:4. Express the change in power generation if the blade length ratio becomes A: B (A and B is the last two digits of your new matric number, if A or B is zero, consider it as a 1). Blade K length, A Blade length, B. Figure 1: Two wind turbines placed side by side
