A recent test of the emergency alert system found only 1 percent got it via AM.

Something to do with Soros buying radio stations ;-) ?

AM radio is a century-old technology. It makes more sense to push
microwatts of light over a fiber, or a few watts from a gen6 cell
node, than to spray tens or hundreds of kilowatts of RF out into the
universe.

Heh. The power needed is not that related to being old technology, but to the frequency used. The lower the frequency, the more power is needed.

I'm pretty sure that the power consumed by modern telecoms
infrastructure exceeds that of broadcast radio manyfold.

  An AM or LW transmitter can be a megawat.
  Google:
 Long Wave Radio These wavelengths travel very long distances and generally use much higher power than medium wave, or FM and DAB. Typical power levels are 500 kilowatts, though some stations transmit with up to 2 megawatts (two million watts).

   A 5ESSS exchange we were setting up took only a few KW, 2 or 5, measured when we tested the batteries. Long distance only, just a dozen local lines.
 

Every cell tower consumes kilowatts and you need lots of them to
reach the same number as a single AM MW or LW station.
