Traditional power plants can take years from start of construction to power generation. Wind plants take months. Wind turbines can be used on land which is supporting another use. Farms or ranches can be source of energy without significant negative impacts. It can only be used practically in areas of relatively constant winds.
Wind generators have lots of moving parts.
They have to be able to handle very high wind speeds which occur in storms. For these reasons they can have relatively high maintenance requirements. Most of this maintenance has to be accomplished at the top of a tall tower in a windy area. Not an easy task. This is one of the main reasons for the use of larger turbines.
