Wind farms require all of the following EXCEPT:
AContinuous sunshine
BLarge open land area
CStrong, steady winds (above 15 km/h)
DBackup storage for low-wind periods
Answer & Solution
Correct answer: A. Continuous sunshine
1. Wind farms work in daylight or darkness as long as the wind blows.
2. They need persistent wind speeds above about 15 km/h.
3. They require lots of land to space many turbines.
4. They need backup storage or alternative supply when winds drop.
5. They do NOT need sunshine; that is for solar plants.
6. So the option that does not apply is continuous sunshine.
