As long as the machine is in S3 mode, that is all the fans and everything
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.
