Here’s a bit of fun: energy environmentalists versus endangered species environmentalists.

From The Washington Post:

Workers atop mountain ridges are putting together 389-foot windmills with massive blades that will turn Appalachian breezes into energy. Retiree David Cowan is fighting to stop them.

Because of the bats.

Cowan, 72, a longtime caving fanatic who grew to love bats as he slithered through tunnels from Maine to Maui, is asking a federal judge in Maryland to halt construction of the Beech Ridge wind farm. The lawsuit pits Chicago-based Invenergy, a company that produces “green” energy, against environmentalists who say the cost to nature is too great.

The rare green vs. green case went to trial Wednesday in U.S. District Court in Greenbelt.

It is the first court challenge to wind power under the Endangered Species Act …

At the heart of the Beech Ridge case is the Indiana bat, a brownish-gray creature that weighs about as much as three pennies and, wings outstretched, measures about eight inches. …

The case probably will come down to a battle of bat experts.There is no question turbines in other locations have killed tens of thousands of bats. Some strike blades. Others die from a condition known as barotrauma, similar to the bends that afflict divers. It occurs when the swirl of the blades creates low-pressure zones that cause the bats’ tiny lungs to hemorrhage. …

‘Wee, sleekit, cowrin, tim’rous beastie, O, what a panic’s in thy breastie!’  – not the bat, but the environmentalist, torn between one moral imperative and another incompatible one.
