CONVERSE COUNTY, Wyo. — It happens about once a month here, on the barren foothills of one of America's green-energy boomtowns: A soaring golden eagle slams into a wind farm's spinning turbine and falls, mangled and lifeless, to the ground.
Killing these iconic birds is not just an irreplaceable loss for a vulnerable species. It's also a federal crime, a charge that the Obama administration has used to prosecute oil companies when birds drown in their waste pits, and power companies when birds are electrocuted by their power lines.
But the administration has never fined or prosecuted a wind-energy company, even those that flout the law repeatedly. Instead, the government is shielding the industry from liability and helping keep the scope of the deaths secret.
Wind power, a pollution-free energy intended to ease global warming, is a cornerstone of President Barack Obama's energy plan. His administration has championed a $1 billion-a-year tax break to the industry that has nearly doubled the amount of wind power in his first term.
But like the oil industry under President George W. Bush, lobbyists and executives have used their favored status to help steer U.S. energy policy.
The result is a green industry that's allowed to do not-so-green things. It kills protected species with impunity and conceals the environmental consequences of sprawling wind farms.
More than 573,000 birds are killed by the country's wind farms each year, including 83,000 hunting birds such as hawks, falcons and eagles, according to an estimate published in March in the peer-reviewed Wildlife Society Bulletin.
Getting precise figures is impossible because many companies aren't required to disclose how many birds they kill. And when they do, experts say, the data can be unreliable.
When companies voluntarily report deaths, the Obama administration in many cases refuses to make the information public, saying it belongs to the energy companies or that revealing it would expose trade secrets or implicate ongoing enforcement investigations.
