Short answer: solar produces ~10 watts per square meter, all factors considered. Wind, even less. USA consumes 3.8T kWh/yr electricity, needing 44,000 square kilometers (20% of Utah) of solar panels & buffer batteries to supply.

Conceivable, but a massive undertaking at a scale having inevitable significant problems ($66T price tag for starters).

($66T = 1m^2 panel + 1kWh battery from https://www.goalzero.com/shop/kits/goal-zero-yeti-1000x-powe... times 44,000km^2. That’s 3 years of the USA‘s entire GDP.)
