What is the disadvantage of windmill
Answers
Disadvantages Of Wind Energy
1) Wind energy requires expensive storage during peak production time.
2) It is unreliable energy source as winds are uncertain and unpredictable.
3) There is visual and aesthetic impact on region.
4) Requires large open areas for setting up wind farms.
5) Noise pollution problem is usually associated with wind mills.
6) Wind energy can be harnessed only in those areas where wind is strong enough and weather is windy for most parts of the year.
7) Usually places, where wind power set-up is situated, are away from the places where demand of electricity is there. Transmission from such places increases cost of electricity.
8) The average efficiency of wind turbine is very less as compared to fossil fuel power plants. We might require many wind turbines to produce similar impact.
9) It can be a threat to wildlife. Birds do get killed or injured when they fly into turbines.
10) Maintenance cost of wind turbines is high as they have mechanical parts which undergo wear and tear over the time.
