What are you opinions on this?
Do you leave you're computer on 24/7 or do you turn in off?
Does it use more energy booting it up everyday or to leave it on 24/7?

Turning it on and off every day doesn't nearly take as much energy as leaving it on. You computer even uses more energy in sleep mode than being off, because the RAM is still active. The only advantage I see to leaving a computer on all night is if it's a server, and scores of people need to access data whenever they need to, or if you're rendering something like video, and it is a really long and high quality project.
I personally have my iMac set to turn on at a certain time, and then my alarm clock goes off, so that my computer is ready as soon as I wake up.

Based on my own tests, at least in my case, turning off my PC overnight has resulted in a power saving. I used to leave two PC's (both with 750W PSU's) running overnight doing background tasks, housekeeping etc. But after getting doing some testing with a household power meter, over a period of a week with the machine running 24/7 compared to switching off overnight, it saved me a few pennies (I can't remember the exact figures as it was about a year ago). In my case, both computers were not sat idle over night, they would have been busy backing up to two or three NAS units, so there would also have been a switch, a router, 3 Buffalo NAS. Both LCD Monitors would have been on, but in Power Save mode.
I had basically set up both PC's to do all their daily AV/AM/AS scans over night, daily backups/sync, defrags / registry cleanups etc etc. Another reason for not doing that now is that it's all pretty much done in real-time during the day on my current set-up.
I will try and dig up the actual values that it calculated I saved... We are talking a few UKP's a year, but not mega bucks...

The Computer will use less power when it it turned off, but turning it on and off 4 or 5 times a day "may" cause your computer to not last as long, as a computer that is just left on during the day. If you have a SSD you will not have that much problems as a Optical drive with moving parts! Well I Hope This Helps You Out! :D

turning off the comp everyday is still very hard on hdd's. as for using less power i would say since the average person is only going to turn it on once during the day less power is used than when it is left on 24/7. now if you are in the habit of turning it off every time you leave the room(say 4 times during the day) you are going to use more power than you would leaving it on 24/7.
