Apowerplantcurrentlyusescoaltoproduceelectricityatacapacityof1million watts and an efficiency of 40% (that is, for 100 MJ of energy from primary fuel, 40 MJ is converted into electricity). By switching the fuel source from coal to natural gas, how much CO2 emission will it reduce in one day? (10 pts). Hint: This is similar to the problem above.
