There's no real need to post like this. For a far less antagonistic way of making your point, try this, instead:
"I like the idea of running maintenance scripts overnight, which lessens the impact on users during their workday. Turning off computers every night can impede that."
However, I have a rebuttal: it's possible to use a Wake on LAN trigger, so the maintenance scripts will still be completed overnight. (My own company uses this, waking computers at 4 am to run maintenance scripts, so that they're ready to go by the time users start arriving at 6, and minimizing the time computers idly chew through the electric bill.)
Granted, for various reasons, not all computers respond correctly to that trigger, but still, for many companies, the electricity savings found by turning off several hundred (or even tens of) computers every night can be a big boost to their bottom line. Especially for large companies, the extra cost of making an occasional deskside visit to manually maintain those few computers that don't awaken is cheaper than leaving all of them on every night and weekend.
