"Grok 5 might end up being nearly perfect on the Humanity's Last Exam and probably point out errors in the question.

"The best way to actually increase the energy output per year of the United States or any country is batteries.
The peak power output of the US is around 1.1 terawatts, but the average power usage is only half a terawatt. So if you just buffer the energy, charge up the batteries at night, discharge during the day, without building new power plants, you can double the energy throughput of the US."
