coworker brought this into work today:

we are going around testing everything. the electric tea kettle is drawing about 1100 watts and 10 amps. the coffee pot is at about 700 watts and 7 amps. the interesting thing is that the coffee pot is at 1 watt just while it is plugged in but in the off mode. so i calculated how much this is going to cost over a 1 year period:
i hope i'm doing my math right here: it will take 1000 hours for the coffee pot to draw 1 kWh. a kWh costs me about 8.65 cents. so therefore, it costs me about 75 cents per year just to keep the coffee maker plugged in.
we are still testing things but here are some other results:
dell monitor in standby - 0 watts
dell monitor on - 28 watts
dell optiplex 745 computer - 70 watts
dell optiplex 745 computer turned off - 0 watts
dell optiplex 745 in hibernate mode - 0 watts
here is some good reading to help you with understanding kWh:

So each cent will add up over time. They say it makes a huge difference.
The Kill-a-Watt does have a feature on it that calculates the cost for you for the hour, day, week, month, and year. You can even program it for the cost per kwh that your utility charges you. I have one also and have plugged just about everything in my house into it. I have some of my results here http://nlange41.blogspot.com/2009/02/vampire-power.html if you care to read it.
