This chapter reviews Georgia Power's transition from a coal-fired power plant to wood as an energy source. The plant, with a capacity of 155 megawatts, has converted to produce 96 megawatts from wood, aiming to replace 10% of coal-fired electricity with wood. This approach could potentially increase U.S. wood consumption by 2.5 times. However, the energy density of wood is less than half that of coal, raising concerns about power density and resource sustainability, as producing 1 megawatt of electricity requires 10,000 tons of wood annually.
