A typical coal from the Montana coalfields might contain 70% carbon and 1.5% sulfur. For each pound burned in a fossil-fuel electric power plant, this coal produces 10,000 Btu of heat, 0.03 pound of sulfur oxides, and 1.2 pounds of ash. Assuming the plant boiler, turbine, and electric generator have energy conversion efficiencies of 88%, 47%, and 99%, respectively, what is the electric energy output (in kWh) for every 1000 pounds of coal burned.
