here is Audubon's - in short, the org is for wind power but only IF
there will be siting scrutiny and minimal impacts to birds/wildlife.

Wind Power Overview
Audubon's Position on Wind Power
Summary: Audubon strongly supports properly-sited wind power as a clean alternative energy source that reduces the threat of global warming. Wind power facilities should be planned, sited and operated to minimize negative impacts on bird and wildlife populations. snip
Protecting Birds and Wildlife: While Audubon strongly supports wind power and recognizes it will not be without some impact, production and transmission facilities must be planned, sited and operated in concert with other actions needed to minimize and mitigate their impacts on birds and other wildlife populations. Several federal and state laws require this and the long-term sustainability of the wind industry depends on it. Wind power facilities impact birds from direct collisions with turbines and related facilities, such as power lines. Wind power facilities can also degrade or destroy habitat, cause disturbance and displacement, and disrupt important ecological links. These impacts can be avoided or significantly reduced, however, with proper siting, operation and mitigation.
Audubon supports the adoption of federal and state guidelines on the study, siting, operation and mitigation of wind power. Guidelines should provide developers, permitting agencies and conservation groups with the legal, technical and practical steps needed to minimize impacts on birds and other wildlife. Guidelines should provide the following essential elements:
Minimum pre-permitting study requirements and guidance on study methods, frequency and acceptable data sources to ensure that wind power is sited in appropriate locations
Clearly delineated siting criteria that designate areas where wind power should not be allowed, such as Important Bird Areas, major migratory corridors, wilderness areas, national parks, wildlife refuges, and other sensitive habitat such as wetlands and riparian corridors
Clearly defined monitoring and mitigation requirements in permits, with periodic reviews and requirements for adaptive management if impacts significantly exceed levels allowed by permit
Guidance on cumulative population impacts assessment and mitigation.
Audubon also encourages wind developers and permitting agencies to consult with wildlife experts, including Audubon staff and local chapters, to help inform study and siting decisions.
