The Obama administration on Wednesday finalised a that lets wind-energy companies operate high-speed turbines for up to 30 years even if means killing or injuring thousands of federally protected bald and golden eagles. Under the new rule, wind companies and other power providers will not face a penalty if they kill or injure up to 4,200 bald eagles, nearly four times the current limit.

Deaths of the more rare golden eagles would be allowed without penalty so long as companies minimise losses by taking steps such as retrofitting power poles to reduce the risk of electrocution.
The new rule will conserve eagles while also spurring development of a pollution-free energy source intended to ease global warming, a cornerstone of President Barack Obama’s energy plan, said Fish and Wildlife Service Director Dan Ashe.
“No animal says America like the bald eagle,” Ashe said in a statement. He said the Fish and Wildlife Service is trying to balance energy development with eagle conservation.
Wind power has increased significantly since Obama took office, and wind turbines as tall as 30-story buildings are rising across the country.
The wind towers have spinning rotors as wide as a passenger jet’s wingspan, and blades reach speeds of up to 170 mph at the tips, creating tornado-like vortexes.
The surge in wind power has generally been well-received in the environmental community, but bird deaths and eagle deaths in particular have been a source of contention.
The birds are not endangered species but are protected under the Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act. The laws prohibit killing, selling or otherwise harming eagles, their nests or eggs without a permit.
It’s unclear what toll wind energy companies are having on eagle populations, although Ashe said as many 500 golden eagles a year are killed by collisions with wind towers, power lines, buildings, cars and trucks. Thousands more are killed by gunshots and poisonings.
Reporting of eagle mortality is voluntary, and the Interior Department refuses to release the information. The Fish and Wildlife Service estimates there are about 143,000 bald eagles in the United States, and 40,000 golden eagles.
Ashe called recovery of the bald eagle “one of our greatest national conservation achievements.”
The rule is set to take effect in mid-January, days before Obama leaves office. President-elect Donald Trump could change the rule or scrap it, but the process would likely takes months or years.
Michael Hutchins of the American Bird Conservancy said Wednesday that his group has “some serious concerns” that the new rule will not do not enough to sustain populations of threatened eagles.
