Carbon Capture & Sequestration: How Hopeful Should We Be?
The burning of fossil fuels provides about 85% of the energy consumed in the United States. One societal cost of this source of energy is the release of carbon dioxide; a potent greenhouse gas. The dream of capturing carbon before it is released into the atmosphere is capturing the imagination of policy makers. The Energy Policy Act of 2005 includes $1.8B for “clean coal” of which carbon capture & sequestration is a component. Yet the questions remain: Can it work? Is it cost effective? Are there more effective alternatives?

Panorama of the East Coast
This Jan. 29 panorama of much of the East Coast, photographed by one of the Expedition 30 crew members aboard the International Space Station, provides a look generally northeastward: Philadelphia-New York City-Boston corridor (bottom-center); western Lake Ontario shoreline with Toronto (left edge); Montreal (near center). An optical illusion in the photo makes the atmospheric limb and light activity from Aurora Borealis appear "intertwined." Image Credit: NASA
