1. A 1 GWe (gigawatt of electrical output) power plant in a developing country burns high-sulfur coal (4% sulfur by weight) without flue-gas desulfurization. Assume that the plant runs at a capacity factor (ratio of actual electricity generated to the amount generated if the plant ran at full capacity for 1 year) of 75%, that the efficiency of energy conversion from heat to electricity is 0.33, and that the heat content of the coal is 30 GJ/t.
