GigE power consumption is typically 1->3 watts per port, at each end of the link.

By comparison, the new 24-port 10/100 switch that we just installed here consumes a mere 3W total with most ports idle, and a max of only 6.5W with all 24 ports active.

But the GigE one is ten times faster, so spends 1/10 as much time transmitting or receiving. That makes GigE at 1-3W/port not much different from 100Mbit at 0.25W/port, if you look at power used per bit.

That would be true, if the switches and interfaces were all powered off between packets.

Dream on.

Meanwhile, that's 26kWH per GigE port per year.
