1.5TeraWatts of continuous average power must be replaced just for the USA which already inludes the efficiency advantages of electric over ICE. With capacity factors as stated (25% for solar and 33% for wind?) The hardware requirements are as previously stated.

And this doesn't even get into the hardware that needs to be built on the consume end of the transition, which is likewise impossible to build that many batteries. Just for the USA. Now envision the whole world making the same transition. Along with underdeveloped countries raising their standard of living so that they no longer have to cook using sticks or poop outside in the yard.

It doesn't add up.

The future will be much smaller and simpler.

The sooner we accept this and quit relying on a false hope of rebuildables replacing 17 TW, the sooner we can make plans on how to get there as humanely as possible.
That 1.5-Terrawatts is not set in cement.I posted elsewhere at this thread that with energy efficiency we can cut your number by 43%.By getting off fossil fuel we can cut that number down another 41%, due to the inherent entropy of internal combustion.
Now we're into Gigawatt territory.
Renewable energy is already in the gigawatt realm.
Just keep adding to it each year and at some point you supplant the existing infrastructure.
