Suggest two reasons why wind power was not able to meet this demand. [2 marks] 1 2 0 1 . 3 Some of the energy from the wind used to rotate a wind turbine is wasted. An engineer oils the mechanical parts of a wind turbine. Explain how oiling would affect the efficiency of the wind turbine.

Figure 4 shows some of the equipment used by the student. Figure 4 This is the method used: 1. Wrap insulating material around the can. 2. Put a fixed volume of boiling water in the can. 3. Place the lid on the top of the can. 4. Measure the time taken for the temperature of the water to decrease by a fixed amount. 5. Repeat steps 1–4 using the same thickness of different insulating materials. 0 4 . 1 Identify the independent variable and the dependent variable in this investigation.
