Georgia: Coal and Carbon

Coal generates carbon dioxide when combusted, which is causing the world to warm. In Georgia, a state that gets over 60 percent of its electricity from coal, some coastal residents are connecting the dots between coal and changes in the local ecology and economy attributed to global warming. Recognizing the need to reduce carbon dioxide emissions, engineers are exploring "clean coal" technology. What is this technology? Will it work?
