I may be missing something but I had 2 homebrew amps running 813s, another
one running 4-572B's by Dentron and recently since 1997 had a Ameritron
AL80B till 2004. I sold all amps because I am satisfied with 100 watts from
the Icom 706 and my QRP rigs. BUT, my point is I never noticed any increase
in my utility bills!
I sent the following in response to the original mention of power costs,
but forgot to forward it to the list:

Let's say you have a 1.5KW amplifier. Overall efficiency might be 50%,
so it draws 3KW key down. Now let's say you operate 2 hours a day, 5
days a week. During that time, you QSO 50% of the time. During a QSO,
you transmit 50% of the time and listen 50% of the time. You use CW, so
your duty cycle is 50%. This will cost you 3KW * 10h * 0.5 * 0.5 * 0.5
= 3.75KWH, or, at the specified rate, about 48 cents a week, or $25 a
year if you always use the amplifier and don't take a vacation. SSB will
be cheaper.
