Q31. What is the term for the process of grouping multiple wind turbines together in a single location?
a) Wind cluster
b) Wind array
c) Wind farm
d) Wind aggregation
Show Answer
Correct Answer: c) Wind farm
Explanation: A wind farm consists of multiple wind turbines installed in close proximity to one another, often in rural or coastal areas with favorable wind conditions, for collective electricity generation.
Q32. Which of the following regions is NOT suitable for wind energy generation?
a) Coastal areas
b) Mountainous regions
c) Urban areas
d) Open plains
Show Answer
Correct Answer: c) Urban areas
Explanation: Urban areas typically have complex wind patterns and limited available space, making them less suitable for large-scale wind energy generation compared to coastal areas, mountainous regions, and open plains.
Q33. What is the term for the process of extracting wind energy using offshore wind turbines?
a) Onshore wind energy
b) Coastal wind energy
c) Nearshore wind energy
d) Offshore wind energy
Show Answer
Correct Answer: d) Offshore wind energy
Explanation: Offshore wind energy involves installing wind turbines in bodies of water, typically oceans or large lakes, to harness wind resources located offshore for electricity generation.
Q34. Which of the following statements about wind energy is true?
a) Wind energy requires large amounts of water for operation.
b) Wind turbines pose a significant threat to bird populations.
c) Wind energy is unaffected by weather conditions.
d) Wind energy has a higher capacity factor than fossil fuel power plants.
Show Answer
Correct Answer: d) Wind energy has a higher capacity factor than fossil fuel power plants.
Explanation: Wind energy often has a higher capacity factor, which is the ratio of actual energy generated by a power plant to its maximum potential output, compared to fossil fuel power plants due to favorable wind conditions.
Q35. What is the term for the process of adjusting the direction of a wind turbine to face into the wind?
a) Pitch control
b) Yaw control
c) Trim control
d) Roll control
Show Answer
Correct Answer: b) Yaw control
Explanation: Yaw control involves adjusting the orientation of a wind turbine’s nacelle and rotor blades to ensure they face into the wind, maximizing energy capture and optimizing turbine performance.
