No. Research shows that wind turbines are at the bottom of the list for causes of bird mortalities. House cats, building collisions, and vehicle impacts all cause death to more birds than wind turbines.
If this still concerns you, painting the tips of wind turbines black can help make their offshoot more visible and thus avoidable for birds.
Wind turbines only produce a mechanical hum, that cannot be heard from a far distance.
Depending on a wind farms site and proximity to residence, it is required to adress potential sound issues and obtain a permit for such disturbances.
No, wind power actually ranks in just below the cost of burning natural gasses and fossil fuels. Within the past decade, the performances and technological advances of wind energy have greatly increased while the cost has decreased.
