Sorry to awaken an old thread.
If you turn it off to transport it you would be better off just turning it off when you finish using it and then running the scripts manually!
Got a tip for us?

Wrong!
He will use the same energy for sleep but will save on the energy wasted charging the battery that doesn't need to be on charge as the machine is asleep!
There's something I don't understand -- if the computer is 'asleep', will it wake up on its own accord to perform the various maintenance scripts during the night?
Exactly, there shouldn't have been any argument about environmental issues here. Do you unplug your TV, stereo, microwave, alarm clock when those are not actually being used?
I do, the only thing that stays plugged in is my macbook, and cable modem. And i'm not sure how that is going to save the world but oh well... If you are so into "environmental science" and "global warming" you should realize that it will happen with or without human involvement. There have already been 5 mass extinctions in Earth's history, we are coming up on the 6th. Search for it.
But that wasn't the topic.
Bump.
Question 1: If the computer is sleeping during the night, will bittorent clients like Transmission still run and download throughout the night?
Question 2: Should I leave the MagSafe charger connected to my MBP while its sleeping? A friend told me its better to charge only when the battery is almost empty, although I've currently had it plugged in everytime I've used the computer.
Thanks in advance for your help.

Put it to sleep, it's what it was designed to do. If you use your machine more than about once every two days then merely put it to sleep rather than shut it down. If you're not going to use your machine for more than two days then shut it down. That's a pretty good rule of thumb I find.
The advantage of sleeping it is that it'll wake up quickly and when it does wake up, it'll run the system's maintenance tasks that should have been run at 3:00AM when, no doubt, your Mac wasn't awake. If you shut the Mac down, it won't catch up on these tasks automatically.
During sleep, the only components getting power are the RAM and parts of the logic board (and the sleep light obviously). Therefore, it has no advantage over shutting down in terms of preserving the moving components of your Mac.
I have seen the similar thread on this topic, and a guy there said "more energy is consumed in startup than an entire month of sleep."

Is that possible?

Most probably not. Although he could be right. A computer sleeping uses very little power, whereas a booting computer uses a lot.
However, waking a sleeping computer uses almost as much energy as booting it. So what he said would only be true if you never actually used the computer, but let it sleep all the time.
I guess it'd depend on the type of computer, the battery health and even the startup/login items applied to the computer as to how much power is actually consumed at startup, however, I see that claim as pretty ridiculous.
If you want to test it, sleep your Mac overnight and measure the percentage loss in battery charge. Then, shut down plus boot up the machine and see how much it has gone down again. Don't use the restart option since that probably won't consume quite as much power and therefore won't be as accurately indicative.

Just a comment on "wasting" energy.
Waste energy from sleeping a mac results in heat. Any time you are not heating your home this is a waste. (although such a small amount, I would not worry about it. but I'm not a tree hugger)
However, in the winter time, this "waste" is actually contributing to heating your house. A small amount, but guess what, whatever the sleeping mac contributes is energy that a furnace/boiler does not have to put into your house.
So in the end, sleeping a mac during heating season leaves NO footprint and "wastes" no power.
Still a Mac novice, but kindof a Physics geek.

Good point. However apart from some notable exceptions, I'd argue it's more efficient to heat a house with an actual heater than a Mac (Power Mac G5 notwithstanding), so therefore using more energy to achieve effectively the same goal is still wasting power.
Why do you want the RAM cleared though? The whole purpose of RAM is to prevent the computer accessing the relatively much slower hard drive. Wouldn't you want stuff in the RAM?

I guess, although because I run my computer 24/7, I've turned the radiator in my room off (it's been off for about 8 years now), and my room is effectively heated by the computer as there's no other source of heat in the room. Point is that my room is one less room the central heating has to burn oil to heat, and I get computing done with the computer, so the 'waste' heat from the computer is 100% useful to me. Only problem is that it can get a little TOO warm during the summer months
