iMac sleep mode, how high is the electricity charges rate?

Power usage in sleep mode is low. This may not belong to your computer, but here's the report for the Mid 2011 21'5-inch iMac > http://images.apple.com/environment/reports/docs/imac_21.5inch_per_may2011.pdf

FWIW, I never sleep desktops, just their displays and run 24/7. Most electromechanical failures occur when they're powered on, so I wouldn't advise turning it off on a routine basis.

"FWIW": For What It's Worth.

You can open your Applications folder>System Preferences>Energy Saver>set the slider shown for "Display sleep:" to the interval you want the computer to wait after the last keyboard entry for the Display only to go to sleep. Then you can set the "Computer sleep" interval with the other slider.
