British business magazine The Economist on Tuesday launched an online debate on the costs and benefits of hydraulic fracturing. It includes a statement of position from a supporter -- Amy Myers Jaffe, executive director for energy and sustainability at the University of California at Davis -- and a critic -- Sierra Club executive director Michael Brune. There's a poll and plenty of space for reader comments. It's sponsored by Statoil, the Norwegian energy company. A link to the site is here.
