Sleep and its power consuming

Because of the time-consuming booting procedure,I usually use Sleep button to turn off computer.However, this utility still consumes electricity so I fear of my energy bill.So anyone know exact how much electricity that sleep state uses.And if the power was shut suddenly,how can I protect my work and data from losing.?Thanks.

Set up S3 sleep state in Vista for significant power savings

And as far as losing your work if there is a power outage, it depends upon whether you use normal sleep or Vista's new "hybrid sleep":

are off. Only the RAM remains powered on and sometimes the keyboard or
mouse if its setup like that.

Typically a computer in S3 state will only draw 2 or 3 watts. Easily less
than 1 percent the power draw of a machine when its on. In the UK we get
charged about 12p p/kWh. So to run a machine in S3 for the whole year 24/7
would cost about £2, about $4.
If hybrid sleep is enabled then it will also save the RAM to disk (called
hibernate) when when it goes to sleep. So that if the machine does lose
power it will reload it all from the hard disk when the machine starts,
it'll take a bit longer to boot this way, but the all the data should be
intact.

You can check to make sure hybrid sleep is enabled by going into Power
Options -> Edit plan settings, and then Change advanced power settings.
Then under sleep there should be an option called 'Allow hybrid sleep' as
long as that is set to yes, all the data will be saved to the disk as well
as being left in RAM.

Here's a bunch on Ebay:

I've measured mine and it's 6W.

Interestingly, it's also 6W when it's switched off, so there is no advantage
in switching off for me, and I always use Vista's sleep mode.

Remember, modern PCs have a "soft off" which keeps the PSU and the odd bit
of the mobo powered.

On mine the only way to get it down to zero is to switch it off at the wall.

Where do you get < 1 percent? Your computer actually uses like 200-300 Watts?
