' Saint'. Nikola Tesla proved he could *transmit* electrical power w/o wires.

Not if you want modulated broadcast radio.  Or telephone systems with overhead wires.  Or fences with wire orthogonal to one of the directed beams.

Be careful with that 'electromagnetic waves hitting the Earth'; I think you're much more likely to get interesting effects from understanding what is behind 'telluric currents' with respect to Tesla broadcast-power experiments.  You might want to read up on what experiments like HAARP are intended to do with electromagnetic 'coupling' with the Earth and its magnetic field, but this is much less 'generating' power than producing very high synergistic effects from a comparatively small injection of charge carriers, much of which involves the rotational inertia more than than any incident radiation.

Now, Tesla's influence on Westinghouse qualifies him for inclusion in the actual electricity Fair Folk, as does the basic use of AC to carry useful power in the space charge around conductors than in skin effect or conduction subject to severe ohmic heating.  It took a very long time, and some decidedly better materials science, to get HVDC (as a necessary part of Edison's 'horse' in the War of the Currents) up to the same level of economy.  And a whole world's worth of spinoff tech to make HVDC-to-LVDC transversion for commercial-power purposes a household-cost-effective technology.

There will still be a market for metallurgical coal and some coking coal. Little Steam coal will be needed in North America.
