Excellent post, I look forward to studying the spreadsheet and other links that you posted.

I've always configured my monitors to turn off after X minutes, usually my screen saver kicks in at 10 minutes of inactivity and the monitor powers off 10 minutes after that. I normally leave my work PC powered up 24/7 except for holidays and vacations, but I just finished reconfiguring it to stand by and hibernate, we'll see how that works out. I just have too much stuff running that I need to go through shut down and power up every day.
