The Drake equation assumes that the ETs will be blasting out

that only in around 1920 or so and already we are doing less

directed sources and no indiscriminate electromagnetic radiation
at all.

I'd look for industrial emissions, such as signals from the cross-
country electric power grid.  But maybe we will quickly improve our
efficiency and reduce energy losses, or switch to a 100% hydrogen
economy.

I'm told that the United Kingdom is unique in having power demand
surges in the evening at particular times each day.  This is
because certain television programmes have large numbers of
viewers, and when the programme breaks or ends, tea is brewed, by
using electric kettles.  With digital choices, catch-up, and
services such as YouTube, this may soon change.  (And anyway, I
recently heard about it once more from the people who broadcast
the television programmes for which claims are made.)

Especially at the end of the soap "East Enders".  Last week a
documentary about Britain included the National Grid controller who
keeps a TV on in the control room, so he knows when the program
ends, and he is able to bring up the various hydroelectric pumped
storage dynamos on time until the 50-Hz average frequency is
stabilized again.

I thought it was the commercial break in /Coronation Street/ that was
the main offender?

Half time in international football games, according to a friend who
works with "serious" electricity.

C'mon .... one drinks beer during footie, not tea, surely. Although 
people have told me that quite a lot of women watch it these days. I 
dunno what the game's coming to.
