A large number of recent FM conversions (sports/talkers) are
extinguishing the stereo lamp. No need for stereo on these stations, and
it does save a small amount on energy bills and increases the SNR on the
fringes.


How would it save energy? FM just turns carrier into sidebands; the
current never changes.

All equipment draws power, that includes the stereo multiplex generator. If
they can switch that off, they save a few dollars a month on electricity.
