Best Buy sells a plug that allows you to control (on/off) the device/appliance from your phone. It also monitors energy usage. I'd be curious to see how much some power of the standard appliances are actually using.

FWIW I checked our last enmax bill and electricity usage was 427 kwh. We have a 3 year old home, 2000 sq feet, 3 bed 2 bath, pretty standard layout with no fancy appliances. We are pretty conscious of turning off lights when not in use but nothing too crazy.
I have family in Surrey BC and they mentioned police monitor energy usage of residential homes as a way of detecting grow ops there (which it sounds like is fairly common). I'm sure they do the same thing here. Of course that doesnt work if the grow op is stealing electricity from another source.
