Air pollution gone with the wind

Compared with the nearly 6 billion metric tons of carbon dioxide released into the air by the United States each year, the 9 metric tons of pollutants a Camp Springs church saved in 2009 by using wind-generated electricity might seem trivial.

But to the members of Davies Memorial Unitarian Universalist Church, paying about $290 extra for the year on their electricity bill for wind power — reducing carbon dioxide emissions equivalent to taking a car off the road for a year — represents an important act of faith.
