What are the disadvantages of wind power?

not available at all times

can't be used everywhere

causes pollution

noisy

can only be used in cities

Wind power are very noisy actually horizontal axis wind turbines are mounted near the ground surface causing more noise than vertical axis.

No pollution since it's renewable source.

We don't use it in cities but in vast empty areas.

Yeah, it's not available all the time as it depends on wind and no human has power over that.
