Having recently gotten into the whole power saving thing, I was wondering if there are UPS's that can record how much power is being drawn out of them? And say, outputting them to a log file the power draw for the past minute/second. I know some UPS's can be connected by USB to tell the computer that they need to shutdown after the power goes off. But logging exactly how much power is being drawn would be rather handy.

I've also jumped on the power usage bandwagon, but to "save the wallet" rather than "save the world". I use an induction device connected inside of the meter box which sends a wireless signal to a digital readout device in my house that shows power usage. My computer uses about 50 watt-hours of energy which costs me about 1 cent per hour, with the 20" LCD screen turned on. It can also download data to my computer and show graphs of power usage over time.

Dick Smith may sell these kinds of devices. Mine is branded as "Efergy".

Hmm, yeah I know about those devices, but I was looking for more a single device for a single appliance rather than a fully fledged house power monitor. I don't want to go down that path just yet, it seems they still need a few more years to fully mature. While there are some really cool ones (I like the currentcost one at the moment), I can't quite afford to fork out for it right now.

Hmmm, I got an Elto power meter, measured power consumption at the wall, the entered the numbers into LightsOut (WHS), so it calculates that all for me :). I think I was originally looking for an at the wall, based solution, but this kinda works.
