The US used ~4000 terawatt hours in 2021, about 900 of that (~20%) renewable.

Barring the discovery and miraculously quick deployment of a resource-effective & cheap energy storage technology, we are still gonna need a quick spooling backup of some sort.

Unless you have a plan to cut energy use by 80%
