I think your numbers are off. It will take 0.6% of the US land to power ALL the US:

Here's the estimate to power the WORLD:

Total Surface Area Required to Fuel the World With Solar | bLAGI

191,817 square miles - to power all humans on earth. Just from solar.

Wind turbines are now often 8MW each - and they are more efficient the bigger they are.

Nobody is proposing to make hydrogen - that takes at least 3X as much energy.
