Wind Power: How "green" is it?

(04/02/08) Over the last couple years, we've reported extensively on the explosion of wind power in the North Country and the passionate debate it's kindled. Are the wind turbines going up across the North Country ugly or beautiful? Do they make too much noise? Kill too many birds or bats? You can find a complete archive of stories on our website, ncpr.org. Today, we're going to put those issues aside and focus on one question: does electricity produced by the wind actually reduce carbon emissions and help stop global warming? In other words, how "green" is wind power really? David Sommerstein reports.
