Answer
The larger the wing area of the blades, the more wind energy is harnessed to rotate the turbine. This leads to increased electrical energy production, as it allows the turbine to capture more kinetic energy from the wind, enhancing efficiency.
Step 4
Name the device installed in the head of the wind turbine to decrease torque and increase input shaft speed to the generator.
