DENVER — As the Obama administration seeks to clear a path for more renewable energy projects, it has increasingly found itself caught between two staunch allies: the wind energy industry and environmental organizations.

Tensions between both groups and the administration have risen since a new federal rule was announced this month allowing wind farms to lawfully kill bald and golden eagles under 30-year permits.

Conservation groups reacted with anger to the rule, saying it gives wind farms too much leeway to operate without sufficient environmental safeguards and does not consider the long-term impact on eagle populations.

“A 30-year permit is like a blank check,” said David Yarnold, president and chief executive of the National Audubon Society, which was involved in months of negotiations on the rule. “It basically says you can go operate these wind turbines and kill as many eagles as happen to die.”
