140 In 2012, the United States produced percent of its electricity in the amount of x 102 kWh from coalfired power plants. Taking the average thermal efficiency to be 34 percent, determine the amount of coal consumed by these power plants. Take the heating value of coal to be 25,000 kJ/kg.

The power plant's net efficiency is simply the heat content of electricity (3600 kJ/kWh) divided by the heat rate (kJ/kWh) (see Equation 2). (2) The power plant's heat rate depends on the fuel type used and the specific power plant design. All the heat put into the plant that is not converted into electricity has to be dissipated somehow to the
