Well what are you going to do about it once you learn that something is using a lot of electricity?
With some things, you can't do anything because you need that thing.
With others, you can turn it off when not in use or reduce your use of that thing.
So instead of monitoring your electric usage and spending money on this, why not spend that money on energy saving appliances, compact fluorescent bulbs, and power strips (to switch stuff off) instead?
Basically cut back everywhere you can.
Around here we had a 13% electric rate increase last spring. People have not noticed this until the last few months.
Things you can do...
Basically there is no one thing which will greatly reduce your electric bill. These are many little things which add up. So first learn arithmetic...
25 cents + 25 cents + 25 cents + 25 cents = $1. One dollar a day times 30 days in a month = $30!
So look for those things which will save you 25 cents. There are lots of them!
A couple of times I've seen compact fluorescent bulbs on sale and subsidized by the local electric company for $1 each. I bought two bags full! Every bulb I can replace is CFL now.
Don't use the dishwasher, wash dishes by hand.
An electric water heater can be 30% of an electric bill. Get a water heater timer and run it only 3 days a week in the mornings. Take showers only 3 days a week - weekdays. Then it will be off the rest of the day and you will have warm residual water instead of hot. (These have a button on them to bypass the timer if you need an extra shower.) Install a valve on the shower head. Turn off the water when you are soaping up. Then back on to rinse.
Get an Energy Star front loading washing machine. Wash with cold water.
Get a new Energy Star refrigerator and window air conditioners if your existing are older units.
Turn the heating down and wear sweaters. Heat just the bedrooms at night (baseboard electric) and turn the house heating way down.
Install Energy Star double pane gas filled windows - use heavy curtains.
Install as much additional insulation as you can, especially in attic.
Close off unused rooms.
Seal all air leaks. Check around doors. Install weather stripping and new bottom threshold if needed.
Then basically anything electrical these days is "always on" and always using electricity. EVERYTHING! Get a bunch of power strips (which do not have a light in the switch) and plug these things in. Turn them off when not in use. This includes microwave, TV, stereo, coffee maker, computer equipment, garage door opener, etc.
Phones will work when not plugged in (except cordless). I only have my answering machine phone plugged in. All the others are unplugged and still work fine. Dial numbers instead of using speed dial.
Place all chargers for cell phones, etc. in one area on a power strip. Turn off when not needed.
For entertainment system, get about 4 power strips (or more) and place them side by side up high where you can reach them. Use one for playstation, one for DVD, one for stereo, and one as the main and for TV. Then turn on only what you need at the time. If just TV and cable box, then just those on. (Might want to leave cable box on all the time as it takes time to download all the info.)
Leave the stuff plugged in and on like the cable box if needed, just turn off with a power strip everything which is not needed.
Same with computer. Place printer on power strip and have off when not in use. Have a main power strip which turns off everything when not in use. (Again these things are always "on" and using a little electricity.)
Do you have an outside GFCI outlet on its own circuit? GFCI's always use a little electricity. Turn off the breaker if this will not be used all winter.
