Consider two coal-fired power plants that generate 5.0x10^12J of electricity daily. Plant A has an overall net efficiency of 38%. Plant B, would operate at with an overall net efficiency of 46%. The grade of coal releases 30kJ of heat per gram. Coal is pure carbon, if 1000 kg of coal costs $30, what is the difference in daily fuel costs for the two plants?

How many fewer grams of CO2 are emitted daily by Plant B, assuming complete combustion?
