If the OP is still around, I'd seriously consider investing in a whole home power monitor. These have an inside display where you can monitor your energy use "live" and also will datalog your energy use with either custom software or Google Powermeter. As you use devices, you can see how much power is being consumed.
There is a complete list on Google Powermeter's site:

The Powerhouse Dynamics one would be the ultimate as you can monitor every breaker independently, but you'd need an electrician to install it, and it's expensive. There are some devices, e.g. Blueline, that only require you install a small optical sensor contraption on the outside of your power meter (no electrical work required) but they are less sophisticated. The TED-5000 is probably the most popular one, it can be installed by someone with basic electrical experience (e.g. can competently install a breaker), and can monitor up to 4 circuits or panels.
TED-5000 is available from a Calgary company, FYI: (Optimum Energy)

You can also monitor individual appliances using a kill-a-watt type device.
