  The climate change emergency calls for a reduction in energy consumption in
all human activities and production processes. The radio broadcasting industry
is no exception. However, reducing energy requirements by uniformly cutting the
radiated power at every transmitter can potentially impair the quality of
service. A careful evaluation and optimization study are in order. In this
paper, by analyzing the Italian frequency modulation analog broadcasting
service, we show that it is indeed possible to significantly reduce the energy
consumption of the broadcasters without sacrificing the quality of the service,
rather, even getting improvements.
