When questions of energy use come up, I find it critical to get some actul numbers on what is going on and there are lots of pretty cheap items to tell us what we are using and very easy.
I suggest doing a search for "kill-a-watt meter" to get a full range of prices, etc. and then plug one in to test for how much you are using. It's also a handy gadget to use around the house to find house much energy we waste when we leave things like power supplies plugged in full time.
About ten dollars and up?
