A coal-fired power plant uses 2000 Mg of coal per day. (Note: 1 Mg is 1000 kg, commonly called a metric ton or simply a tonne.) The energy value of the coal is 28000 kJ/kg. The plant produces 2.8 x10^6 kWh of electricity each day. What is the efficiency of the power plant? How much energy is wasted?
