I usually shut my PC down when I'm done using it to save electricity. Does sleep mode use much power, or is the difference pretty small?
Does putting a PC to sleep use much electricity compared with shutting it down?

Sleep does use electricity, but usually a small amount compared with leaving the PC fully on. It keeps enough of the system powered to resume quickly, including memory in traditional sleep mode.
Shutdown generally uses less, though a plugged-in PC can still draw a little standby power. The actual difference depends on the computer and its settings.

If you want a number for your setup, a plug-in power meter is the easiest check. Measure the PC in sleep and after shutdown, then compare the readings.
For a rough cost, multiply the difference in watts by the hours it spends in that state, divide by 1,000 to get kilowatt-hours, and multiply by your electricity rate. Small wattage differences add up slowly, but the rate and hours matter.

Hibernate is another option. It saves the current session to the drive and powers down rather than keeping the session in memory. Resuming can take longer than waking from sleep, but you can get back to your open work.

A hibernating PC can still use some standby power while plugged in, just like one that's shut down.

For a short break, sleep is handy because it wakes quickly. If you're finished for the night and don't mind starting fresh, shutdown is a simple choice. Neither setting is the same as leaving the PC on to run background tasks or access it remotely.

Monitors, speakers, and other peripherals can draw standby power too, so the PC alone might not be the whole total.
