Daniel Yergen and another energy 'expert' were on the University of Texas at Austin's NPR program, Energy Switch a few days ago.
They were reluctant to 'predict' beyond a decade or so, but did say that, by 2040, USA wind production would increase by 3X. Grid-scale solar by 4X. Along with widespread efficiency increases across all phases of energy use.

Infinitum Electric, of Round Rock,Texas recently showed their new axial-flux, 'Aircore' electric motor at the Consumer Electronics Show.
* 66% less copper
* 50% weight reduction
* 50% size reduction
* 50% less shipping carbon footprint
* 10% higher efficiency
* 30% lower emissions
* switchable, variable-phase ( 3-phase-to-18-phase) operation
* 76-US Patent applications
* 33-US Patents issued so far
* By reducing non-traction electric motor loads by 10%, along with 10% for the traction motor, overall BEV efficiency is increased by over 10%.
* The motors are completely rebuildable, serviceable.
* These efficiency improvements would constitute 'negawatts' added to USA generating capacity, expanding capacity at zero expense to providers, via load reduction. Just like aerodynamic drag reduction or lower rolling resistance in cars, or higher R-Factor in homes and businesses.
