Step 1
Step 2
State TWO problems associated with wind turbines used to generate electrical energy.
Answer
-
The unreliability of the wind: Wind is not always consistent, which can lead to fluctuations in energy production.
-
Noise pollution: The operation of wind turbines can create noise that may be disruptive to nearby residents and wildlife.
Step 3
Name and describe TWO devices installed on a wind turbine to ensure maximum efficiency of the turbine blades.
Answer
-
Wind Direction Meter: This device orientates the rotor/propeller properly into the wind, allowing the turbine to capture maximum wind energy.
-
Wind Speed Meter: This meter measures the speed of the wind, which indicates how effectively the blades can harness the available wind power. The turbine can adjust its position for optimal performance.
