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.
