A coal fired plant generates 600MW of electric power. The plant uses 4.8 x 10^6 kg of coal a day. The heat of combustion of coal is 3.3 x 10^7 J/kg. The steam that drives the turbines is at a temperature of 573K, and the exhaust water is 310K.
What is the overall efficiency of the plant for generating electric power?
How much thermal energy was wasted?
*Help, I'm SO lost!*
