I am focusing on the pulsed klystrons in the NEXRAD weather and TDWR stations

ERP is not the same thing as raw wattage 'into the waveguide'.  It involves 
antenna gain and the transmitter output can be much smaller.

Many TV stations saw huge reductions in energy use after the digital 
transition.  With analog, you needed a really strong signal to look good. With 
digital, you either get a perfect picture or no picture at all.

Cell transmitters can be relatively small for this reason ( compared to an 
analog transmission).  I wouldn't worry about RF generally except to the extent 
that people have a transmitter (cell phone) on their person.
