One such disadvantage is the visual impact on the land, since they are very large and quite tall to capture the wind, they may not compliment the land very well because they are very obtrusive. Another major disadvantage is that the wind does not always blow, so the wind turbines would be useless if there was no wind to spin the blades which generates electricity. Although meteorologists can predict wind patterns and place them in areas where the wind will most likely flow, meteorologists wont always predict the weather patterns right. The weather patterns are always changing, so if previous wind plants were placed in an area where the wind had flowed greater, that may not be so in a couple of years or decades. Another disadvantage would the required maintenance, but most moving parts need maintenance sometime in their life. And even though these wind turbines are supposed to be Earth/Wildlife friendly, bats can still be affected by them since they rely on sound waves to fly. When bats send out a sound wave it may move in between two blades causing the bat to think that it is safe to keep flying where it is headed, but as it is moving, so may the blades and it might fly right into the wind
