Here is another article that does actually mention the other energy requirements

Energy gain in this context only compares the energy generated to the energy in the lasers, not to the total amount of energy pulled off the grid to power the system, which is much higher. Scientists estimate that commercial fusion will require reactions that generate between 30 and 100 times the energy in the lasers.
