Unexpected Downside of Wind Power

Thousands of aging turbines stud the brown rolling hills of the Altamont Pass on I-580 east of San Francisco Bay, a testament to one of the nation's oldest and best-known experiments in green energy.

Next month, hundreds of those blades will spin to a stop, in what appears to be a wind-energy first: Facing legal threats from environmentalists, the operators of the Altamont wind farm have agreed to shut down half of their windmills for two months starting Nov. 1; in January, they will be restarted and the other half will be shut down for two months.

Though the Altamont Pass is known for its strong winds, it also lies on an important bird-migration route, and its grass-covered hills provide food for several types of raptors. "It's the worst possible place to put a wind farm," said Jeff Miller, a wildlife advocate at the nonprofit Center for Biological Diversity. "It's responsible for an astronomical level of bird kills."

Isn't it funny that nuclear energy sometimes seems to be the cleanest and safest source of energy? Using alternative sources, like wind, water (including tidal power) or solar engery isn't perfect; may it affect a bird or fish.
