The thin clients themselves won't go into power-saving mode, but on my 
LTSP setup, the monitors do.  A lot of the juice to run a thin client 
(say, a Pentium-166) would normally go toward spinning the hard disk and 
keeping the monitor lit up.  Since we unplug the HD's, that power is 
never used in the first place.  :-)  Pentium-166 and even 233 CPU's 
don't really use up that much juice...not like a Pentium-III, Athlon, or 
especially Pentium 4!

So, yes, you do get your "environmentalist" power savings with thin 
clients.  Plus, if you use "old" Pentiums and such, you're keeping them 
out of the landfill for much longer than you would otherwise.
