You misread. That’s the energy it used.
It produced energy greater than all the energy used on the earth at one time.
Much different.
Ok, basic science here. It can’t have put out more energy than was put in. The capacitors / batteries used to store the energy we charged for an extended period of time. The total energy put out for an infinitesimal period of time was a percentage of the sum of the energy put in.
Even as I write this, I think I see an answer to my question. It was a certain amount of TOTAL energy, stored over time to charge the capacitors, all discharged in that one tiny moment.
The microwave oven is a false flag comparison.
Zap anything in it’s way.
