The Texas Hill Country, home to the world's largest remaining bat colonies, has been the focus of proposals for wind energy projects. We are deeply concerned about the potentially serious consequences to Hill Country wildlife - ironically, from an energy source commonly promoted as "green." ...While we feel it is the private landowner's decision whether to participate in wind energy development, overarching concerns for wildlife create a need for caution. Development of wind energy in areas of high wildlife usage, such as certain Hill Country and Gulf Coast sites, should be avoided until credible scientific documentation of threat levels and solutions has been gathered. ...The environmental consciousness demonstrated by AES SeaWest in the Hill Country must be emulated throughout the wind-energy industry. Companies that put wildlife at risk cannot claim to produce "green energy."
