In this Nov. 13, 2012 photograph, cone sections of the gasifier coal feed system Cyclonic Baghouses, left, await final placement at Mississippi Power's Kemper County energy facility near DeKalb, Miss. On the right are the cylinder sections of the lignite coal storage silos. The plant, still under construction, is designed to use a soft form of coal called lignite in a gasification process to generate power. The project has come under legal challenge by the Mississippi Sierra Club. The environmental organization says the gasification technology is expensive and unproven. (AP Photo/Rogelio V. Solis)
