Those figures are about maximum dispatchable power usually for a time of more than 1 hour (2 to 4 seems typical). So 16 GW battery allow you to power the US si

  Somewhere between 4 and 8 minutes worth of storage deployed over the span of a whole year is not even remotely close to feasible. Even diurnal storage to even out solar production will require 8-12 hours worth of storage. Seasonal intermittency will require days or even weeks. Since 2020, battery prices have gone flat. Moore's law works because computers get faster as transistors get smaller. That's not the case for batteries, or most other goods. A new car cost a million dollars in 1900, $100k in 1910, and $10K in 1920. Would it have been reasonable to assume that a new car would cost $10 by 1950? Of course not, the steel and rubber in the car is worth much more than $10. A car cannot cost less than the input materials used to build it. Input materials account for 75% of the cost of a battery already (https://www.visualcapitalist.com/breaking-down-the-cost-of-an-ev-battery-cell/ https://www.visualcapitalist.com/breaking-down-the-cost-of-a...) The room for further price reductions become ever more slim.
