[kwlug-disc] [OT] linux server power

You can do some things to reduce power consumption without purchasing. You 
could turn off or remove the extra xeon processor. That could save $84/year. 
Memory is surprisingly power hungry too so removing the extra ram, if any, 
would increase efficiency. Using cpu scaling will turn down the MHz on the 
remaining processor to again reduce power consumption.

Please note that 100W v 7W and $7.00 / month was for one of the servers,
the VoIP server.
The other server(s) is(are) another matter and another set of
assumptions, calculations, and considerations.

And, so far, I have avoided the "carbon footprint" in my contributions.
John Van O mentioned:

It takes energy to forge silicon and metal and oil to make plastics and 
transport products. The carbon footprint of a new computer may be larger 
than that of your electrical bill.

I will add, the manufacture of  semiconductors i.e. CPUs, bus-bridges,
video accelerators, etc. has a surprisingly large carbon footprint.
This is part of the "dark side" of the high-tech industry which likes to
promote itself as 'clean' and 'green'.

But then, I studied vacuum tubes and I shudder when I imagine the carbon
footprint of typical home w/o semiconductors.
