Usage monitoring

To monitor the usage, I needed to purchase an item which would help me learn about how much devices consume.



I've chosen the Efergy Wireless energy meter (it was a final choice between that one and the Owl), which I've bought off eBay today. It should arrive in a few days, just before I take a week holiday.

I'm looking at consumption, not price or CO2 emissions here, but this device supports them all. One reason for getting it now is to measure how much electricity consumed when no one is at home - the only usage should be background stuff. I wonder, how much does the house cost before we do anything?

I saw this unit demonstrated by a friend of mine a couple of months back. I think their usage will be a lot less than mine, but this is a good way of finding out!
