Natural gas power plants work by burning natural gas and using the resulting heat to produce steam. This steam is then used to spin a turbine and output electrical energy to the grid. Each natural gas plant outputs energy to the electrical grid at a certain rate Pout (output power) and has a certain operating efficiency e. We consider three natural gas plants I, II, and III that have different values of the output power and efficiency:
| Plant | Output Power | Operating Efficiency |
| 1 | 421 MW | 0.57 |
| 2 | 703 x 103 kW | 0.63 |
| 3 | 0.678 GW | 0.60 |
Over the course of running for a week, which plant produces the largest amount of waste heat?
