What are the advantages and disadvantages of wind energy?

Advantages

The advantages of wind energy are more apparent than the disadvantages. The main advantages include an unlimited, free, renewable resource (the wind itself), economic value, maintenance cost, and placement of wind harvesting facilities. First and foremost, wind is an unlimited, free, renewable resource.

Disadvantages

Aesthetic impact: Many people are concerned with the visual effects that wind turbines have on the beautiful scenery of nature. They believe that giant wind turbines distract viewers from the beautiful surroundings. Fig. 2 shows just how big wind turbines can be.

Wildlife: Wind turbines may be dangerous to flying animals. Many birds and bats have been killed by flying into the rotors. Experts are now conducting research to learn more about the effects that wind turbines have on marine habitats.

Remoteness of location: Although this may be an advantage (placing wind turbines in desolate areas, far away from people), it may also be a disadvantage. The cost of travel and maintenance on the turbines increases and is time consuming. Offshore wind turbines require boats and can be dangerous to manage.

Noise: Some wind turbines tend to generate a lot of noise which can be unpleasant

Safety at Sea: In the darkness/at night it may be difficult for incoming boats to see wind turbines thus leading to collisions.
