As people around the world become more concerned about the global energy supply and how to satisfy a growing need for power, many have promoted a greater reliance on coal, and proposed that coal can be made "cleaner" through new technology. However, half of America's electrical supply is currently created through burning coal, and scientists have cited it as the largest current source of greenhouse pollutants. Is "clean coal" a practical possibility? Are the claims of the coal industry always accurate? What are the alternatives in the future of energy? And what about the land-use issues of mining coal and disposing of its waste? Filmmaker Peter Bull collaborated with journalist Jeff Goodell to create Dirty Business: "Clean Coal" and the Battle for our Energy Future, a documentary that examines the issues behind coal and confronts the controversies concerning its impact on the environment. Dirty Business was an official selection at the 2010 Full Frame Documentary Film Festival. ~ Mark Deming, Rovi
