PORTLAND, Ore. – In 10 years Oregon has handed out $1.3 billion in tax credits for renewable energy and conservation projects like wind power, but questions about why the state is spending so much on something that may have a hidden environmental drawback have been raised by some.
Wind power is touted as the cleanest and greenest renewable energy resource.
"You've got a non-carbon-emitting source of energy that's free," said Doug Johnson of the Bonneville Power Administration.
However, Todd Wynn of the Cascade Policy Institute says it’s not as clean as advocates claim. He says it’s simply because the wind is volatile and doesn’t blow all the time.
