Don't forget the photovoltaic systems which are becoming very popular now 
because of financial benefits (at least in Germany). Nice rural areas with a 
very low level of noise will be more and more very noisy.

Obviously the Yanks aren't listening to BBC quite as much, but if it matters, 
my closest neighbors, about 1/4 mile (or 400m) away would make 30M unusable 
when their plasma TV was turned on.  I have empirical data... My RF 
environmental noise is something to boast about until the plasma TV's come on.
