The Obama administration released new rules Friday for protecting wildlife from wind farms.
In a morning news conference, Interior Secretary Ken Salazar said the voluntary rules offer ways to reduce the number of birds and bats that are harmed by wind farms. They focus on choosing sites with low wildlife risks, and designing the sites to avoid disturbing habitat.
Supporters say the guidelines will help developers follow existing requirements to protect endangered species, migratory birds, and golden eagles.
But advocates with the American Bird Conservancy have fought unsuccessfully to make the new guidelines mandatory. They say the new rules won't do enough to protect birds because they're not enforceable.
