Step 1
Step 2
Suggest two reasons why wind power was not able to meet this demand.
Answer
- The wind was unreliable on that particular day, which may have caused the wind turbines to not generate enough power.
- There could be too few wind turbines in the UK to meet the high demand of 34,000 MW on that day.
Step 3
Explain how oiling would affect the efficiency of the wind turbine.
Answer
Oiling the mechanical parts of the wind turbine would increase its efficiency by reducing friction. When friction is minimized, less energy is wasted, allowing a higher percentage of the energy generated to be converted into useful work. This means more of the energy from the wind would be converted into electrical energy, thus enhancing the overall efficiency of the turbine.
